Types of grinding attachments for engravers. Budget consumables for an engraver

Allows you to perform an impressive range of material processing operations various kinds. However, it is impossible to fully realize the potential of such a tool without the availability of appropriate equipment. However, understanding the variety of attachments for drills will not be difficult.

The entire range of accessories for hand drills can be divided into three categories:

The main one is intended to work for the intended purpose of the tool.
Additional - expanding the capabilities of the drill.
Other, allowing to increase the convenience of work, ensure repeatability and manufacturability of processing.

Each type of equipment has its own characteristics of choice and use, so we will consider them separately.

Basic equipment

The direct purpose of drills is to remove material from small areas of a part according to a complex profile and shape. It can be done different ways, having previously determined suitable processing modes. In total, two groups of modes can be distinguished: cutting (milling) and grinding.

Milling attachments

The first and most extensive class of equipment for drills is burrs. various types. All their diversity can be classified according to a number of characteristics, of which the size and shape of the working part are of the most important practical importance. The bur tip can be needle-shaped, spherical, disk shape, and also have a flame tongue profile, a cylinder with a straight and rounded end, a straight and reverse cone.

According to their design, burrs can be divided into solid carbide, steel (including those with a carbide tip), and diamond:

Solid carbide burs made of tungsten carbide are designed primarily for large material removals, their main working surface is the side. These cutters are usually quite large in size and are designed to maintain cutting properties for a long time. Big size The bur allows a wide variety of side surface profiles, which contributes to high-quality shaped processing of grooves and grooves. For solid carbide, the cut pattern of the cutting edges, their size, shape and sharpness are extremely important. There are straight, cross and spiral cuts, which contribute to maximum effective removal chips, depending on which part of the cutter is used as a working part and what material is processed. A separate type of burr - spear-shaped, serving as a kind of analogue of gravers and single-flute cutters, as well as studded ones. These are extremely productive tips for roughing deep grooves and cutting edges.

Brazed steel burs have a common drawback - poor resistance to lateral loads, which often results in the working head breaking off. The main working surface of such burrs is the end surface; they are designed to form deep grooves and grooves complex shape. There may be no soldering, which makes such a burr unsuitable for working with dense and hard materials. The main advantage of steel burs is their relatively low cost with high durability; this tool is most often used in the manufacture of parts made of plastic and soft wood.

Diamond burs- most universal tool. Thanks to the powder coating, all surfaces of such a nozzle can be equally effectively used as working surfaces. The disadvantage of diamond burs is their low performance at low speeds, as well as their relative fragility when processing viscous and consumable materials. The area of application of diamond burs is the processing of natural and artificial stone, bones and hard steel alloys. The durability of diamond burs is determined by the number of layers of diamond coating (1, 1.5, 2), as well as the degree of coverage of the cutting particles with a binder (35-60%).

Most varieties of cutting equipment are of dental origin, and the notation system was borrowed from there. Burs are distinguished by a colored band on the clamping part, depending on the fineness of processing. Carbide burs and green-banded tips are designed for quick removal of large amounts of material. Burs without a color designation, as well as with a yellow and white belt, have 8, 16 and 30 cutting edges, respectively. Color coding also used for diamond burrs: black, green and unmarked tips have correspondingly increasing grain sizes for roughing, and red, yellow and white have the smallest diamond grain size for fine finishing.

Sanding and polishing

The second type of processing that drills specialize in is abrasive grinding. In part, diamond burrs could also be classified as grinding equipment, but in reality, during grinding, active wear of the working part occurs, while the powder of the diamond tool practically does not crumble.

Grinding using drills is used at the final stages of processing and is not intended for removing significant portions of material. The characteristics by which grinding equipment is distinguished are the same as those of milling cutters: the size and shape of the working part, as well as the cleanliness of the processing.

Grinding stones are the most common type of attachment for rough processing of simple surfaces. Disc stones are used for grinding external surfaces, cylindrical cutters for internal ones. The color of a stone determines its grain size, but general classification in this matter no, each manufacturer arbitrarily determines the labeling. Grinding attachments are also completely varied and differ in a number of ways:

The design is one-piece or on a holding rod. The fundamental difference is small: replacement stones are simply more profitable for large volumes of work, but at the same time, serious problems with alignment may occur. It is recommended to use rods and nozzles of the same series, since the landing diameters are almost always different.
By type of abrasive. There are abrasive natural stones, electrocorundum and polymer-bonded silicon carbide, as well as fine-grained rubber-bonded abrasives. Each type of abrasive and binder is used exclusively for a limited range of materials specified by the manufacturer.
In terms of size and shape, the situation is almost the same as with burrs. In this regard, the choice depends solely on the dimensions and type of the part being processed. By the way, most stones can be easily edited to give the desired profile.
By the presence of plasticity. Grinding stones can be either absolutely hard or slightly elastic. The latter property makes it possible to process surfaces with a fine texture, but microscopic particles of the binder can become heavily packed into the pores of the material being processed.

Also included in this category of equipment are polishing attachments. These are discs, balls and cylinders made of felt, felt or muslin. Typically, polishing attachments are replaceable and are used in conjunction with a landing rod. It is possible to mount with a screw or on a cone thread - there is no fundamental difference. Such attachments are designed to work with abrasive pastes: dry polishing is also possible, but for materials such as wood this often results in burns.

Additional equipment

Other types of processing tools can also be mounted on holder rods. This type of equipment is mainly used for rough and preparatory work. We have specially placed this type of attachments in a separate category: they are completely short-lived and rather belong to the category of consumables.

Cutting and grinding wheels

On a standard rod with a tightening screw, cutting and grinding wheels. The latter are often made by hand using round cuttings from ordinary abrasive paper. Cutting wheels are designed on the same principle as discs for angle grinders, but most of them do not have a reinforcing cord, which is why they quickly fray and crumble under strong pressure. Diamond cutting discs are the most durable type of additional equipment; they are mainly used for cutting stone and other hard, infusible materials.

Flap type cylindrical grinding heads are widely used, as well as cylindrical clamps for abrasive belts. There are also flap sanding discs used for cleaning complex textured surfaces. Metal and polymer-abrasive brushes are especially popular. Disc accessories of this type can also be mounted on rods with a screw clamp.

Features of choosing collets and flexible shaft

All described types of equipment have standard shank diameters of 1.6, 2.35, 3 and 6 mm. Some manufacturers, such as Dreamel and Proxxon, may use individual shank sizes for certain types of nozzles. The problem of incompatibility is solved by selecting collets of the appropriate diameter or adapters. Particularly popular are extended adapters for dental cutting heads. Adapters must be selected for each individual drill, taking into account the diameter mounting hole in the spindle.

For greater ease of operation, flexible shafts can be used to provide access for the working body to hard to reach places. Almost all flexible shafts on the market have the same range of characteristics, only the length and diameters of the connections differ. Thus, the flexible shaft can simultaneously serve as an adapter for a different shank diameter. Flexible shafts are designed mainly to work with grinding and auxiliary equipment: working with cutters requires a rigid connection to the spindle, while the shaft core has significant radial elasticity.

Other devices

To conclude our review, we will mention some devices whose task is to make work easier and further expand the range of capabilities of the tool. First of all, this concerns vertical feed stands, which allow you to turn the drill into a small drilling machine.

One of the most popular accessories for drills is the milling support platform. This element must be selected individually for your drill model, because quite often the tool and the equipment do not have the same thread pitch and density. At milling sites, the list of housing attachments is not limited: there are also dust collectors, limiters, various kinds of stops and jigs, but their acquisition or manufacture is usually associated with the need to perform some complex processing operation.

There are simply a huge number of different tools on sale that can be used for machining details. An example would be an engraver. In many ways, this tool is similar in its operating principle to a drill or grinder, but is designed for working with small-sized workpieces. By purchasing and installing various attachments for the engraver, you can carry out grinding, milling or engraving, as well as drilling. It is important to choose the most suitable options execution of nozzles, since they are characterized by different performance qualities and scope.

Features of nozzles

Attachments for wood drills can be classified according to a fairly large number various signs. There is a wide variety on the market. Almost all equipment for an engraver is characterized by the presence of two structural elements:

The shank is a part of the engraver attachment, due to which it is mounted in the chuck of the equipment used.
The working part is responsible for directly removing the metal layer at the time of processing.

Metal engraving paste is used to significantly increase the efficiency of the processing, especially if the engraving tool is intended for surface grinding. Descriptions of attachments may be provided by manufacturers, since the cutting edge of some versions may have complex geometry.

Equipment for an engraver can have simply a huge amount distinctive features. Drill burs and other types of equipment can be classified according to the following criteria:

Type of material being processed.
Purpose of the drill and the engraver attachment used.
Areas of use.

An example is diamond cutters for engravers, which can be used to process the end surface and obtain a surface of complex shape.

The use of hard spraying can significantly extend the service life of the cutting edge, as well as provide higher cutting conditions. A mini drill bit for a drill is used to obtain blind or through holes with a minimum diameter. The main classification can be called the purpose for which technological task the engraver attachment is purchased. By providing diversity in this indicator, the scope of application of the engraver is significantly expanded.

By type of material processed

When choosing the most suitable set, attention is paid to what materials it is intended to work with. The classification of tools in this case is as follows:

Most of the options are designed for working with wood. As an example, the wood engraving cutter has become widespread. It can be used to obtain various patterns. If necessary, ensures high processing accuracy.
An engraver with appropriate attachments for working with metal is used. In this case, when making a cutting edge, more wear-resistant and hard alloys are tried on. When choosing tooling, it is important to pay attention to what kind of alloy will be processed. An example is the ratio of the hardness of aluminum and hardened steel.
Glass equipment is purchased quite often. This type of material is difficult to process. That is why the cutting part is often made of wear-resistant alloys or diamond chips.
There are attachments for engravers that are designed for working with stone. The diamond cutter for stone has become quite widespread. The high hardness of the processed surface determines that special requirements are placed on the cutting edge.

The purpose of the type of material being processed largely determines the cost of the equipment. The most affordable offer is considered to be wood cutters, which have become very widespread. There are also often versions designed for working with metals.

By purpose

A tool for engraving on metal or wood can be intended for a variety of operations. Based on this feature, the following execution options are distinguished:

For engraving work. Very often it is necessary to apply some kind of drawing or inscription on the surface. If the work is carried out in a home workshop, then an engraver can be considered a more suitable tool. There is an engraving cutter for metal or wood, artificial or natural stone, glass and other materials. Diamond burs (cutters) are often sold as a set, since to obtain complex drawings and inscriptions may require attachments with different cutting edge geometries.
Tools whose attachments are represented by a combination of solid metal rod and an abrasive tip. In some cases, it is necessary to improve the quality of the roughness of recesses or other complex surfaces. In such cases, this type of equipment is used. Its purpose is to rough and finish the surface, it all depends on the grain size of the abrasive material used.
For grinding and polishing work. On sale you can find a huge range of engraver grinding attachments. Various materials can be used in their manufacture. An example is classic abrasive or felt.

When choosing, it is worth considering that there are a variety of pastes for engraving and other engraver attachments intended for grinding surfaces. Their use can significantly increase the efficiency of the operation. The selection of paste is carried out in accordance with the specific tool used for processing and what material the part was made from. Before using any paste, you should pay attention to the instructions for use.

When considering the classification, we will also pay attention to the fact that there are working attachments for professional engravers. They are intended to be a multi-functional tool that can be used to perform a wide variety of operations. The most common set of such equipment is represented by the following combination:

Cutters that have different shapes and sizes.
Cones made of abrasive, felt or diamond coating.
Drills that can be used to transform a conventional engraving machine into an efficient drill for precise drilling work.
Wire nozzles, which can be used to clean the surface.
Cutting discs designed to remove part of a product.

If desired, the set can be assembled by purchasing all the attachments separately. However, some versions are extremely rare on sale, which makes it difficult to purchase them separately. Let's take cutting discs as an example.

A set of attachments for the engraver is produced under various brands. As previously noted, when frequently processing workpieces with the tool in question, a fairly large set of attachments is required. The following factors may influence your choice:

What specific technological tasks will have to be performed. As previously noted, a drill can be used to carry out simply a huge number of technological tasks: engraving, surface grinding, cutting, drilling and others. The choice is made in accordance with what kind of work will be carried out. There are universal sets available for sale, represented by a combination of nozzles of various types.
Characteristics, geometric features workpieces and type of material used in manufacturing.
Estimated dimensions of workpieces. A tool that is too small is not convenient for processing larger workpieces. However, achieving your goals may take much longer.

The set of cutters and other attachments can be minimal or include several dozen units. In this case, the choice depends on the budget allocated for the purchase of equipment and how often the work will be carried out.

When choosing, attention is also paid to the classification according to the purpose of the sets:

Professional level. The high cost of such an offer is primarily due to long term service and exceptional performance. In addition, the cutting part retains its shape over a long period, which ensures precision processing. It is advisable to choose such equipment only when the relevant work is carried out frequently.
Budget proposals. This group can be divided into simply a huge number of categories. The most affordable tool will be an offer from Chinese manufacturers, but it will not last long and often does not meet the stated characteristics. Some famous manufacturers also produce instruments of this class, but at the same time they withstand quite high level quality. That is why, when work is carried out infrequently, attention should be paid to such a proposal.

When purchasing a tool, you can inspect it. There should be no obvious mechanical defects on the surface. In addition, a lot of attention is paid to symmetry, which is quite difficult to check without special equipment.

Making your own nozzles

For some surfaces, it is difficult to find a more suitable nozzle on sale. That is why many are considering the possibility of making them themselves. An example is Dremel cutters for wood, which have also become quite widespread today.

You can make a cutting disc or grinding head in your home workshop. A primitive cutter is represented by a grooved cylinder from a conventional lighter. The sanding attachment is made of a wooden drum to which sandpaper with the required grit value is attached.

Do-it-yourself engraver attachments are made because they can replace completely purchased versions. However, it is very difficult to make wood carving attachments with your own hands. This is due to the fact that the working part of such a tool has a complex geometry, which can only be replicated by a true professional using special equipment.

At self-production equipment, attention should be paid to the fastening features. The corresponding element from a broken tool can be used as a shank.

In terms of functionality, using an engraver is in many ways similar to working grinder or drills. But there is one important distinguishing feature- it is used for processing miniature parts.

Thanks to the use of this device in combination with a set of attachments for the engraver, it is possible to perform such technological operations as grinding, milling, drilling, engraving, etc.

Main features of nozzles

The tool is designed for finishing a fairly large number of various materials. It can be used to process ceramics, wood, glass and plastic products, hard steel.

To work with each of them, different nozzles with different design specifics are used.

Today specialized enterprises offer a wide range of various attachments necessary for performing operations with this instrument. Their design contains two main components:

the working part that performs the main function when interacting with the product being processed;
a shank that secures this element in the equipment socket.

When choosing this device, pay attention to certain points: the technological goal that needs to be achieved, and the material being processed, or more precisely, its characteristics.

In addition, take note of the equipment of some engraver models collet chucks. Only certain brands of attachments are suitable for them. To use such equipment you must additionally acquire universal collets.

Among the most popular types of attachments included in professional kits are diamond burs. The basis of such equipment is made of tool steel.

At the same time, the working part coated with diamond powder. Thanks to the latter, the device is capable of quite successfully processing steel, glass, ceramics, natural and artificial stones.

The use of diamond burs is most advisable if there is a need to refine a shaped hole. They are most often sold immediately in sets of ten to twenty pieces, varying in shape and size.

The operation of burs must be carried out in compliance with certain rules , helping to prevent damage to the diamond coating. Standard models are equipped with a shank with a diameter of three millimeters.

Abrasive attachments

Inexpensive options for this equipment include parts consisting of rubber and abrasive material. They are used to work with metal products and stainless steel items.

Sets of abrasive attachments usually include five or six instruments with a different shape of the working part. The shank of such equipment is 2.3 mm.

Some companies are engaged in the production of abrasive attachments different colors , thanks to which the user can quickly understand a specific category of tool. For example, red abrasive powders are used to work with metal. They are made from aluminum oxide.

But the tools, painted green, are intended for manipulating glass, ceramics and stone. They are sprayed from silicon carbide. To ensure the convenience of various technological processes, the working part of the abrasive nozzles manufactured in several types of shapes.

Abrasive devices allow you to perform the following operations:

Sanding the surface of the part.
Boring holes.
Engraving, etc.

They are used to process necessary materials at home. Wherein professional craftsmen Usually such tools are not used because they do not have sufficient functional potential.

Polishing and grinding attachments

As already noted, engravers are used to polish objects made from different materials.

Typically used for this type of work felt nozzle, which is pre-coated with a special polishing paste that acts as an abrasive component.

Polishing discs can be used for both rough and final finishing. They are also often used when the need arises surface finishing having an irregular shape.

To choose the most suitable paste, you must first determine the properties of the material of the product that needs to be sanded. For processing hard metal surface, for example, it is advisable to use pastes based on polishing powder and paraffin.

And for finishing wood, mixtures made from from diamond dust with different fractions of grains. They can very effectively get rid of scratches on glass and wooden surfaces and bring them to a perfectly smooth state. In this case, the most recommended powders are those containing diamond fractions 5/3 and 3/2.

Felt attachments for grinding can be used both when processing wood, metal, glass, and to equip drills in dental clinics or simple hand-held devices.

Work kits for professionals

The professional series equipment is represented by a separate category of attachments.

Good craftsmen usually have at their disposal sets of tools that differ design, materials of manufacture, shape of the working part.

In most cases, such kits consist of the following components:

Various cutters for engraver.
Abrasive, diamond and felt nozzles.
Drill, thanks to which the installation can be used as a drill.
Cutting discs.
Wire nozzles used to clean the surface from dirt and corrosion.

All these kit components allow the specialist to produce neat and high-quality work even very small parts. To do this, of course, quite often it is necessary to change the tools used to select a more suitable equipment option for a particular situation.

But the end result is worth it. The presence of a large set of masters is often evidence of his professionalism and experience.

Most popular brands

On modern markets There is a wide range of attachments for engravers. Thanks to this, you can choose exactly those tools that will correspond to your financial capabilities and the needs necessary in a particular case.

If we talk about equipment professional level, some of the most popular and sought-after brands include “ Dexter and Dremel" The products of these companies can be effectively used for processing metal, wood, glass and other materials.

Although these devices are different high cost, however they are quite reliable and durable in use. One nozzle of these brands can last ten times longer than its Chinese counterpart. In addition, these tools have high processing accuracy.

As a budget brand it is worth pay attention to the company "Zubr"”, offering to buy a set for a relatively small amount, including up to 180 units of various attachments with different shapes, sizes and design features. Such kits are equipped with tools for drilling holes, milling, diamond and abrasive attachments, and cutting discs.

As for equipment from Chinese manufacturers, there is a very mixed opinion about them. Although they cost several times less than high-quality instruments, such instruments cannot boast of their reliability.

Moreover, Chinese kits contain significantly fewer components than branded versions. However, professionals in their field will, in principle, be able to cope with such equipment. True, you will have to change tools often.

Making your own nozzles

To carry out simple engraving work at home, necessary tools can be made from scrap materials.

For example, the simplest milling cutter is made made from a corrugated wheel from a lighter or a dowel on which working teeth are pre-cut.

To make a sanding attachment, it will be enough to use a wooden drum equipped with a shank with sandpaper glued to its side surface.

Most hand-made attachments cope well with the tasks assigned to them. At the same time, their costs are minimal.

Which equipment option to choose depends entirely on from the requirements and capabilities of the master, be it a Chinese-made instrument, a homemade one, or a professional one.

A drill is a device designed for creativity and handicrafts related to carving and grinding. This device is necessary for drilling holes, carving plexiglass, wood, metal, grinding various surfaces, making engravings. Most often, all kinds of accessories for a drill are included with the device: drills, cutting wheels, polishing discs, felt, brushes, cutters. However, it is better to choose attachments for beginners yourself to make using them as comfortable as possible.

A drill is a device designed for creativity and handicrafts.

A drill can have several other names: miniature drill, engraver. Most often, such devices are multifunctional, as they are complemented by a huge number of different attachments.

When purchasing a wood carving machine, you need to pay attention to the following characteristics:

The shaft lock button and the trigger element should be located close to each other. This arrangement will allow the artist to quickly change his occupation without being distracted from his work.
The average power of the device should be 180 watts.
Torque should be averaged between 5000-35000 rpm. Many models offer the technician a choice of speed. A device with a low-torque function will be appropriate for making engravings.
The weight of the device should not be too large, otherwise it will be difficult to use for a long time. The optimal weight is considered to be 400-600 grams.
If you want to work in a place far from an outlet, you need to select a model with a battery.

An indication of the battery charge level brings a certain degree of convenience to the device. This function allows you to charge the device on time and not miss work deadlines. Therefore, in order to answer the question: which drill to choose, you need to evaluate the direction of your creativity and its requirements. Based on these indicators, the device that is optimal in its functionality is selected.

How to make an engraver for small jobs with your own hands?

If a master does not want to purchase an expensive device, he can make an engraver for small jobs on his own.

Necessary components and their characteristics:

A flexible shaft, as well as a working attachment, which will allow you to fix the device in its clamping mechanism. A cable can be used as a flexible shaft to activate the car's speedometer. Working attachment made from a textolite block: ground to the required dimensions, equipped with a stepped hole on the inside. The diameter of the hole is selected based on the dimensions of the fixed area of the cable: it must be securely fixed in it. The front nozzle area is equipped with a tube, inside of which a freely rotating chuck, made of 2 halves, fixed to each other with a screw. A tool having a 2-5 mm shank diameter can be inserted into a balanced chuck.
Tools for processing.
Drive motor - any motor that operates at a voltage of 220 volts: from a tape recorder, washing machine, electric toothbrush. The best option The motor is considered to be from a sewing machine, since it is equipped with a rheostat that allows you to regulate the speed characteristics of the shaft.

During the work you will also need electric drill, grinder, a set of locksmith tools. Do-it-yourself assembly of the device is carried out on the basis of the following drawings.

Assembling a drill

After preparing all the structural elements, you can begin assembling the device.

A homemade device is made according to the following instructions:

The first step is to make a simple base frame. This base will allow you to securely fix all the elements of the device. In the manufacturing process of this element, a textolite or thick plywood sheet can be used. A piece of the required size is cut out of the material.
According to the arrangement of elements, an electric motor and a bracket equipped with a clamp are attached to the base. The latter will serve as the basis for fixing the rear tip of the flexible shaft.
Pulleys taken from unnecessary household appliances are fixed to the electric motor shaft, the movable core of the flexible shaft. To perform fixation, holes are made in the flange area of the pulleys, as well as on the shafts, necessary for placing the pins. You can make connections more reliable using epoxy resin.
Then the future drill is equipped with a rubber belt. This element is installed on the pulleys of the flexible shaft and electric motor.
TO electrical supply the motor is connected.
The working nozzle is fixed on the front end of the flexible shaft.

To ensure safe operation of the tool, a plywood casing is required for the electric motor and belt feed. Before starting work, it is necessary to test the serviceability of the manufactured device.

Principle, features of work

A self-made engraver resembles a drill or a grinding machine. However, its main purpose is considered to be the processing of small parts. A homemade hand engraver allows you to perform the following actions:

drill;
mill;
polish;
engrave.

Soft woods, hard steel, ceramics, glass with a high level of fragility, plastic, and bone can be selected for processing. During the processing process, it is necessary to use various attachments that are selected for each specific material.

A machine made according to the instructions described above will work according to the following principle:

With the help of pulleys and a rubber belt, electric motor rotation is transmitted to the flexible shaft area.
It is sent via a flexible shaft to the working attachment.
The working nozzle processes the fixed element.

This tool can be made using a different scheme. It requires connecting a flexible shaft to an electric motor using an adapter coupling. Fixation occurs according to the following scheme: one tip of the coupling is placed on the electric motor shaft and secured with a pin, the movable tip of the flexible shaft is fixed in square hole located at the other end of the coupling.

Cones, attachments, cutters: which ones are suitable for a beginner?

Working accessories used to work with an engraver are characterized by their wide variety. To do right choice When selecting nozzles, several factors must be taken into account:

features of the processed material;
technological tasks.

Engravers who work with the device constantly recommend purchasing a set of attachments at once, which includes items of various sizes, types and purposes. At the first stage, a novice engraver will need a small set of tools, including a couple of dozen elements of various types.

Diamond and abrasive burs

Most often, engraving machines are equipped with diamond burs. Main feature This tool is that the main part of the body is made of tool steel, and its working surface is covered with a layer of diamond powder. Another name for this tool is a cutter. Diamond burs are necessary for processing hard surfaces.

Most often, engraving machines are equipped with diamond burs

Most often they are used when working with the following materials:

glass;
steel;
ceramics;
stones.

Most often, cutters are used for finishing shaped holes. Basically, these elements are sold in sets that include 10-20 tools.

More budget option are rollers with work surface made of rubber and abrasive material. They are used for metal work. You need to use abrasive cutters for boring holes and grinding. The capabilities of these tools are optimal only for beginners.

Other attachments

Milling cutters for beginners should be selected in small sizes. With their help, the engraving will have a neater appearance. Most often, for beginners, sets of cutters are offered, consisting of 4-6 elements of various shapes: cylindrical, end, worm, conical, end. Large kits should only be purchased by experienced craftsmen.

You will also need a drill during the work process. This tool is necessary for cutting through the design. Most often it is used to make the outline of a picture and the main elements of the background.

If you need to make holes, you need to purchase a set of drills. This accessory will turn your drill into a drill. If an artist needs to regularly clean the surfaces being treated from corrosion and other dirt, he needs to purchase wire attachments.

How to make a drill with your own hands in 10 minutes (video)

A home engraving machine will allow you to make interesting engravings, as well as wood carvings. It is worth considering that the descriptions presented are suitable for assembling a machine for beginners. For professionals, it is necessary to choose more powerful designs that allow you to adjust the torque speed. Also, professional creativity requires an expanded set of tools, each element of which will perform its own function.

An engraver, otherwise called a mini-drill, dremel, straight grinder or drill, is multifunctional tool. With its help, not only engraving is applied, but also drilling, grinding and performing other operations for processing various materials, for example, wood, metal, glass, stone. The device is widely used both in everyday life and in various industries, in jewelry, and in the creation of advertising and souvenir products. All variety functionality equipment is due to the fact that there are different attachments for the engraver.

Attachments for frequently performed types of work are supplied complete with the tool. Milling cutters for more specific operations must be purchased separately. In order to work correctly and productively with a Dremel, while achieving high quality processing of parts, you need to know the existing types of equipment, as well as for what work each type is used.

Exists a large number of varieties of equipment for working with a mini-drill. The wide range on the market allows you to select attachments for wood and many other materials that engraving equipment can work with. Also, individual craftsmen make them themselves.

Structurally, the attachments (burs) consist of two parts;

tail, clamped in the tool chuck (diameter from 0.8 to 8 mm);
worker who processes materials.

Equipment is classified according to two main criteria:

by the type of material from which they are made;
by area of use (purpose).

By type of material processed

Based on the material, engraver cutters are of the following types.

There are also combination burs that have a steel shank and a carbide working part. Their area of application corresponds to the material of the head.

Carbide equipment is of high quality, durable and is one of the most expensive consumables for Dremels. The shape of the tips determines the features of its application. With the help of such peak burs, it is good to process bone, plastic, and make tracing (indicate the contours of the picture). Diamond bits They are also distinguished by their quality, even if the kit they are included in is classified as cheap consumables.

On the market you can find a set of burrs, all the elements of which marked with any color– it indicates the level of sharpening. Those marked black are the most productive burs, while the sharpness of green or blue ones is worse. Labeled yellow nozzles are optimal choice by doing finishing blanks

By purpose

You can use an engraver with attachments not only for engraving, but also for performing other work operations. The breakdown of consumables used in the operation of straight grinders is presented in the table below.

Work performed	Nozzles used
engraving	the varieties discussed above are suitable
drilling	performed using steel or carbide drills
polishing	circles made of felt, cotton, felt, sandpaper, skin, and special devices(holders) that can be wrapped independently (for example, with felt)
grinding	grinding stones (of various shapes and from different materials) and wheels (of sandpaper), diamond rings, rubber cylinders
tongue and groove	burs with a spherical working part
cutting	cutting discs
milling	cutters
cleaning surfaces (for example, from rust, scale)	wire (steel), thread, fabric brushes
finishing of holes or cavities	diamond cutters
creating grooves	cone burs

Consumables from each group can be used during processing various materials. Wherein milling equipment used mainly by professionals.

Dremels, which have a flexible shaft installed, are equipped with any types of consumables that fit the diameter of the tool chuck.

Review of the most popular attachments for working on wood and metal

Wood is one of the most commonly processed materials for engraving, along with glass, metal, and stone. Dremels are often used for carving wood, drilling miniature holes in it, and applying images to surfaces. of this material, grinding, and creating small grooves or tongues. Therefore, popular types of attachments for woodworking are:

wood cutters;
drill;
cutting circles;
polishing, grinding wheels and cylinders;
spherical and cone-shaped burs;
