Mini drills and engravers comparison. The best engravers according to customer reviews

Today one of popular types work in decoration and jewelry production is engraving. If we talk about the tool used, then in most cases an electric engraver is used for engraving, which is also called a dremel, drill or mini-drill. Let's consider what types of electric engravers there are, which one to choose for the home, which one for professional work, where they are used and the criteria by which they are divided.

Engraver design and characteristics

The tool is a modification electric drill, enclosed in a body held with one hand. It is somewhat reminiscent of a large fountain pen, at the end of which the working attachment rotates. Anyone who has seen a drill in a dentist's office already has an idea of how this tool works.

The device body contains the following components: an electric motor, a gearbox, and a spindle. A working tip (nozzle) or a flexible shaft of different lengths is fixed into the spindle (in this case, the nozzle is located at the end of the shaft). To cool the electric motor, a fan impeller is located on the axis, blowing the engine through special air intake holes.

The principle of operation is almost similar to the operation of an ordinary drill. As a rule, electric engravers weigh about a kilogram, which allows you to work with one hand. Any tool has a set of characteristics by which the user selects a specific model. And if the supply voltage of the device corresponds, most often, to the mains voltage, then such properties as rotation speed, the presence and length of a flexible shaft, and weight can differ within a fairly wide range. Serious differences can be in the systems for adjusting the speed of rotation of the working tip, the number of nozzles included in the kit and other options.

Goals and Applications

With an electric engraver you can perform many different operations. In general, the scope of its application covers a lot professional work and hobbies in various fields of activity where the use of conventional power tools (drills, grinders, screwdrivers) is limited due to their rougher action. For example, if you need to drill a hole with a diameter of 0.2–0.4 mm, not everyone can do it accurately with a standard tool. With the help of an electric engraver this work can be done more accurately. The same applies to the operations of grinding, cutting, and milling various materials.

Several areas of use of the tool:

engraving on almost any material (jewelry, design, decoration);
modeling;
watchmaking;
production and improvement of fishing baits;
household use for various operations with small details and objects;
cleaning seams, polishing surfaces in hard-to-reach places.

It is clear that the list of works for which electric engravers are used can be much longer, but there is no point in describing all possible applications.

Intensity of use as one of the selection criteria

During the selection process, the question is often asked: by what main parameter should the tool be divided? For some, the main criterion is price, for others it is the manufacturer. However, for technical characteristics, cost and well-known brand, one point is often forgotten - how often and with what intensity will the device be used? Sometimes the answer to this question determines the choice of a specific model, the required equipment, the need for additional functions. It is clear that a device professionally used for engraving on metal, stone, glass every day for 5-6 hours should be different from what is used for crafts or hobbies maximum 1-2 times a week.

Since there is no shortage today, a tool can be chosen in such a way that it ideally matches the assigned tasks and does not have redundant, unnecessary functions. For amateur and household purposes, a tool with a power of 100–200 W is quite sufficient; for professionals, units from 250 W are more suitable. You should also select the functions inherent the desired model- from the point of view of whether these capabilities are really needed. After all, there are many parameters that electric engravers can be equipped with today; which one to choose is not an easy question. Here you should use common sense. It’s a shame when, from a list of options consisting of three dozen items, 2–3 of the simplest ones are actually used.

Engraver appearance and operating comfort

Not always, but quite often, the appearance and ergonomics of the tool become the determining factor for the choice. Before purchasing, you should definitely hold the engraver in your hand and see how comfortable it is to hold it. If the instrument fits comfortably in your hand, is it too heavy? Is it possible to work with it for several hours, will your hand get tired? It would be useful to look at the quality of materials, neatness of assembly, whether the switch and adjustment controls are conveniently located. Comfort of use depends not only on the tool, but also on the data of the person working with it. Therefore, the device must be selected for a specific user to make it as convenient as possible.

It also makes sense to pay attention to the convenience and speed of changing attachments, the tightness of the flexible shaft, the softness and quietness of operation. If squeaks and knocks are heard from a new instrument, perhaps you should think about whether there is a need to purchase it.

Of two absolutely identical devices, having identical characteristics and even the shape of the body, in most cases a person will choose the one that looks better. Simply because it is more pleasant to work with a beautiful instrument.

Since electric engravers are, as a rule, light in weight and dimensions, the level of noise and vibration is also low. The tool is several times quieter than a standard drill. Accordingly, the comfort of its use is higher.

Manufacturer and cost

Power tools are manufactured by many companies today. Many of them have earned an outstanding reputation for quality, reliability, and careful assembly. These are Defort, Makita, Bosch, Dremel, DWT. Good engravers are made by Skil, Sturm, Einhell. IN Lately have proven themselves well and domestic producers- Zubr, Energomash, Whirlwind.

It is clear that the price of a tool, depending on the class, manufacturer and purpose, can vary quite significantly. Here you need to decide on the necessary properties, compare several models, and then make a choice. If the engraver is used infrequently, then there is no point in overpaying for a professional model. You only need to be wary of very cheap devices from unknown manufacturers, without a guarantee.

In the end, the choice may not be difficult. You need to spend some time on reviews from owners and recommendations from professionals, compare the necessary parameters with those that the models you are interested in have, identify the cost limits - and the number possible options will noticeably decrease. An important role is played by the equipment of the device, as well as the number of attachments supplied with the tool. It’s a good idea if the engraver comes in a case containing special sockets for attachments, a flexible shaft and other additional accessories. It is convenient for transportation and storage, everything is in its place.

From the author: Hello, dear readers! Engraving is an incredibly popular trend in decoration. Convenient portable tools allow you to perform quite complex operations manually. This also applies to mini drills (engravers), which are used to create unique souvenirs and individual gifts for loved ones. Today we will tell you which mini drill is best to choose for professional and home use, what important parameters you should pay attention to, and also consider the best network and battery models of 2019.

Types and purpose of engravers

Hand universal tools are used to process various materials: stone, precious metal, ceramics, glass, wood. With its help, it is possible to perform drilling, milling, grinding, cleaning work, and apply inscriptions and drawings to the surface. The presence of a practical and reliable collet mechanism allows the use of a large number of interchangeable attachments: trimming and polishing wheels, burs, drills, cutters. A mini-drill is used in production or at home - where accurate and high-precision work is needed: in jewelry and watchmaking, decoration, design, grinding in hard-to-reach places, narrow openings, etc.

By appearance the tool resembles a straight grinder, the main elements of which are: motor, gearbox, shaft, housing. Operating principle: pressing the start button starts the electric motor, rotational movements are transmitted through the gearbox to the spindle, which drives the working equipment.

Engravers are:

electric- operate from a fixed network;
battery-powered- lithium-ion batteries are used as a power source;
with flexible shaft- a hose of different lengths with a steel cable inside, which is mounted between the equipment and the spindle. It acts as an extension cord and makes work more comfortable. The tool can be held with one hand, like a regular pencil, and applied to the surface with patterns, inscriptions, and decorative processing;
laser- tabletop, floor electrical machines, which are solid-state (allow you to process metal) and gas (used to work with any materials, including genuine leather, glass).

Main settings

When choosing an engraver Special attention given:

device weight;
liner rotation speed;
number of working equipment included.

Professional craftsmen prefer lightweight drills with an attachment speed of 18 thousand per minute and a large number of additional accessories. At the same time, the weight of the tool does not exceed 1 kg, which allows you to perform a large amount of work without rest.

The variety of attachments affects the functionality of the instrument and the complexity of the operations. The work can be used:

collets, cam-type mechanical clamps, couplings;
nozzles for decorative carving;
cutting and grinding wheels;
drill;
burs.

Below we list the main criteria that you should pay attention to when choosing a mini drill:

Frequency of use

How often do you plan to use the device? When you need to perform large amounts of work every day, you should give preference to a reliable model with a power of at least 250 watts. This will allow you to engrave at low speed due to the high torque.

Type of processed material

You can grind and engrave glass and wood products at a speed of no more than 20 thousand revolutions per minute. For steel and precious stones, it is better to use a tool that develops a torque of up to 30 thousand revolutions and can be adjusted. For precious metals - an engraver with a speed of revolutions per minute from 15 to 18 thousand.

Dimensions and weight

Modern devices are manufactured with compact dimensions and low weight. This is achieved by the absence of an air cooling system. To avoid overheating of the internal mechanisms, you need to take breaks from work for 15–20 minutes.

Power

An important indicator on which productivity, processing quality and price depend. For home use, an engraver with a power of about 210 watts and a working equipment rotation speed of up to 22 thousand per minute is suitable. Pro-class models are available with power starting from 250 watts.

Shank rotation speed

This characteristic determines the quality of the processed material. Grinding and polishing are carried out at low engine speeds - otherwise, microdamages will form on the surface. And sharpening and cutting are done at high speeds. In modern models, the shaft rotation speed ranges from 15 to 35 thousand per minute.

Advice! When purchasing, check for speed control. High-quality products are equipped with this function, and budget models are equipped with a device that reduces the voltage of the electric motor. They are not suitable for high precision tasks.

Snaps

Of no small importance when choosing is the presence of a flexible shaft and the number of working accessories in the set. In some cases, it is more profitable to buy a high-quality mini-drill with a minimum number of attachments and, if necessary, purchase them separately.

There are a large number of equipment:

made of aluminum oxide or alloy steel- they can be spherical, cylindrical, round, they allow processing ferrous and non-ferrous metals;
diamond coated- used for cutting marble, glass, tiles;
silicon carbide- for processing stone, plastic, ceramics;

made of rubber with the addition of abrasive chips- for grinding various surfaces;
felt balls- allow you to polish various materials using a special paste, which can be purchased separately or included in the kit;
from fine sandpaper- used for sanding wood, steel products, etc.

Typically, working attachments are attached to the engraver using keyless chuck. There are models with a collet chuck, which, although it requires more time when changing equipment, clearly centers it in the collet. They are recommended for use when performing high-precision operations. For various kinds When working, it is better to have both types of cartridges on hand.

Auxiliary components

Functionality modern engravers are expanded with the help of various auxiliary devices, including:

corner equipment- allows you to work in hard-to-reach places, can turn a mini-drill into a multifunctional angle grinder;
flexible shaft with a vice or bracket- increases comfort during use;
rack- makes a drilling machine out of a mini-drill.

Noise and vibration

Most modern manufacturers do not include this characteristic in the description of the models. To find out these indicators, just start the device. As a rule, problems with noise are observed in engravers with average productivity; cheap ones do not vibrate due to low power. The optimal noise level for comfortable use should not exceed 80 dB.

Price

Each buyer has individual needs for quality and cost. Some prefer the convenience and productivity of the device, others prefer the popularity of the brand, or, conversely, the low price. By purchasing an engraver from a global manufacturer, you get proper quality, official guarantee and free service maintenance. However, not every master needs multifunction device at a high cost - it all depends on the frequency of use and complexity of the work.

Important! Engraver from famous brand can't be cheap. Otherwise, it is most likely a fake.

Prices for mini drills vary greatly. The most simple model will cost 20 US dollars, and multifunctional tool pro class - 1200 and above. A tool suitable for beginners average cost- 30–120 dollars.

Rating of the best engravers of 2019

When choosing here or another brand of mini drill for home or professional use, first of all, focus on your own needs, brand popularity and customer reviews, which will allow you to purchase high-quality, reliable and useful tool, which will last for many years.

Proper use of the engraver

The process of use includes the following points:

allocation of free space on the countertop;
installation of a powerful lamp to illuminate small parts;
covering the surface with cloth or thick paper, because during the cutting process chips and dust are formed;
preparation of carpenter's tape, felt-tip pen, pencil for transferring the drawing. Sticky paper tape will allow you to attach the sketch to the surface; after removing it, there will be no streaks left.

Important! Before applying the pattern, metal, plastic, glass surface need to be treated with alcohol or solvent. The pattern is applied to the wood with a pencil.

preparation of working equipment - the instructions for the model describe the purpose of each of them and the possibility of processing a particular material;
Installing a suspension allows you to minimize vibration and cutting errors. It should not interfere with the flexible shaft;
Beginners are recommended to choose the minimum number of revolutions - they will be able to get a neat and clear pattern, lines of the same depth;
the drawing is first outlined along the contour, after which small elements are drawn;
At the final stage, the pattern is polished with a soft felt nozzle, which allows you to remove all irregularities from the surface.

Safety regulations:

before connecting to the network network cable checked for integrity;
To protect the eyes from dust and sparks, use special glasses;
If the nozzle gets jammed, pull it out until the device is disconnected from electrical network or disconnecting the battery is prohibited;
If the plastic case is very hot, the device should be allowed to rest for some time. Due to lack air system Cooling needs to be done frequently. This will prevent overheating of the motor and failure of the engraver. The optimal operating and cooling times are indicated in the instructions;
When purchasing additional consumables, you should make sure that they fit the characteristics of the model.

Daily care

For a complete and long work devices need to perform status monitoring working attachment. When an external inspection reveals certain damage, it needs to be replaced. Only in this case the manufacturer guarantees efficient use of the device and a long service life.

Carefully clean the ventilation holes on the housing, as air flows through them to cool the engine. When cutting or grinding PVC or wood products, the holes become littered with particles of debris and dust, which negatively affects the productivity of the engraver and leads to its premature failure. Cleaning should be done with a dry soft cloth. By following these simple rules, you will be able to use the tool long time and get high-quality work results.

Engraving is one of the oldest methods of decoration. People carved designs to decorate their homes and tools, and the work of skilled craftsmen was always in value. Today this craft can become available to everyone thanks to an electric engraver or mini drill. Engravers can be used for applying patterns to various materials, making jewelry, modeling and all kinds of small work: drilling, sanding, polishing. These tools have a wide range of applications due to a large number nozzles

Device

The engraver resembles a drill or grinder, consists of a housing with a motor and a movable shaft with a mount for a working attachment. Please note that the collet (chuck for clamping equipment) can have a different diameter and is only suitable for attachments with a certain shank size. The most common size is 3.2 mm, but collets for engravers with a diameter of 1 to 4 mm are also available. The chuck can be quick-release or screw-type, requiring a key for fastening. The key one is more reliable, can withstand heavy loads, and the quick-clamping one reduces the time for changing attachments.

Exist impact and rotary type engravers, they differ in the mechanism of operation. Impact hammers function like a mini hammer drill and are only suitable for engraving, while rotary hammers are a more versatile tool, allowing you to grind, drill and cut. Engravers are also distinguished by type of power supply; there are mains and battery-powered ones. Like other tools, network models provide more power, and battery-powered mobility. More expensive engraver models are equipped with a shaft rotation speed controller. It can be electronic with fine tuning or simple mechanical, limiting the motor voltage. Impacts allow you to adjust the depth of travel of the nozzle.

Characteristics

Shaft rotation speed. This is the main characteristic of the engraver. It is higher than other power tools and can be from 15 to 35 thousand revolutions per minute. To work with soft materials(wood, plastic, copper) and polishing will not require high speeds, and for dense products made of stone or steel, you should use a tool with at least 30 thousand revolutions per minute. For impact engravers, the corresponding characteristic is the number of strokes per minute, which can reach 6000.
Engine power. Another important parameter that directly affects the performance of the tool. Measured in watts (W), there are devices from 35 to 300 W. Please note that the price depends on the power, so if you do not plan to use it professionally, then it is quite possible to purchase a low-power entry-level engraver. For long-term work, especially with hard materials, you should take an engraver with a power of 200-300 W.

Engraver attachments

Nozzles (cones) are sold individually or in sets, from small ones of five or six pieces to universal sets that include one hundred or more items. The equipment differs in shape (cylindrical, disk, spherical, conical), purpose and material from which it is made. There are a huge variety of attachments for various purposes; they can be roughly divided into two groups:

Carving and grinding. For cutting, milling and grinding hard metal and stone, nozzles coated with industrial diamonds or aluminum oxide are usually used to soft goods Silicon carbide abrasive is used for wood, glass and ceramics.
Polishing and cleaning. For polishing, you can use vulcanite nozzles or rubber ones with an abrasive coating. Felt and felt attachments are used with a special polishing paste, which consists of paraffin and sanding powder of different grain sizes. Various brushes are used for cleaning; for example, a metal brush can remove rust, paint, or create scuffs for an antique effect.

Choice

It is worth deciding in advance what materials you will be working with, why and how often you will use the tool, this will greatly facilitate the choice of model. You shouldn't be limited by what's included; most likely you'll use a limited number of attachments. Therefore it is better to take good tool with the basic set. You will still have to purchase consumables sooner or later, especially if you are constantly using them for specific tasks. When choosing, pay attention to the ergonomics, dimensions and weight of the device. Working with an uncomfortable engraver will make you tired faster. The weight of such devices can be from 500 grams to 2.5 kilograms. Besides, important indicators, especially during prolonged operation, are noise levels and heat generation. Low-power devices do not heat up or make much noise, and professional engravers usually equip them with a cooler. Some devices come with a flexible shaft, a device similar to an extension for rotary engravers, which increases maneuverability and significantly improves convenience. The tip of the flexible shaft is thinner than the tool, which is better for fine and precise work. When using it, the engraver should be mounted, for example, on a special stand. For work you should choose a powerful one professional tool from manufacturers such as Dremel, Proxxon, Foredom, and for hobbies a household model from the brands Bort, Einhell, Hammer, Skil, Sturm and others is suitable. Follow safety precautions and do not neglect protective equipment. Fine dust and chips fly around during operation, so be sure to wear goggles and a mask.

In the decor of the premises, elements with engraving have great importance, create new directions and styles. Regular drill or an electric engraver is suitable for this purpose. Almost anyone can work with it. Of course, without the necessary skills and expensive tools to talk about high quality not worth the work.

Structurally engraver– grinding equipment small size, which is used for small jobs such as grinding, milling, cutting and drilling of products made of different materials. An electric motor is installed in its body, a collet chuck in which the necessary attachments are attached. Some models are equipped with a flexible shaft that transmits rotation to the nozzle. The functionality of the tool is determined by the number of attachments used. In a set their number can exceed 100 units.

These devices are mainly used by precision equipment repairmen, designers and jewelers (they are also used to perform other small jobs). The tool is whimsical, for this reason it must be selected individually for certain work and material.

An engraver will help you make patterns on exclusive gifts, souvenirs and jewelry. Now you can use it to process any material. It is only necessary to take into account the hardness of the material and use suitable nozzles for it.

Types of engravers

The design of an engraver is not much different from a conventional electric drill, only its dimensions are smaller and it has more capabilities. Electric drive The mechanism, in addition to creating the necessary torque, provides the required number of revolutions of the nozzle. Most engravers work using the principle of rotation, but some devices turn electrical energy into kinetic energy of impact. Nozzle made from very durable material, knocks out unnecessary places on the workpiece, forming the desired inscription or drawing.

A quality tool from a well-known brand costs big money. Engravers from the most famous manufacturers and their main characteristics:

Model	Characteristics	Purpose
Sturm GM2317FL	Diameter of nozzles 1.6, 2.4, 3.2 mm, device power 170 W, 8-32 thousand revolutions, weight 700 g, 120 nozzles and additional accessories	DIY Tool

There are also mini drills that can do the job of an engraver.

A small mini-drill differs from impact engravers in that it can be used not only for engraving work. It allows you to polish, deburr, drill and cut material. Before purchasing, you need to find out what is sold complete with the tool, otherwise for some types of work you will have to buy the necessary attachments separately, which will be expensive.

Choosing an engraver - what to look for

The main qualities of engravers that need to be taken into account when choosing:

Tool weight;
Shaft rotation speed;
How many attachments are included in the kit?

Craftsmen often choose a lightweight engraver, with a working part speed of about 20 thousand per minute, with a large number of attachments. The weight of the engraver should not be more than 1 kg, otherwise your hands will get tired when manually processing parts. A lightweight tool will allow you to do more work without stopping to rest.

The variety of attachments affects the range of functions of the tool. For this reason, the quantity depends proportionally on their number possible operations. The accessories included in the kit may include:

Cam clamps, couplings, collets;
Nozzles intended for engraving;
Polishing and cutting wheels;
Small size drills;
Various burs.

Additionally, in addition to attachments, you can connect to the engraver flexible shafts, which, due to their length, allow you to perform work in hard-to-reach or inconvenient places without experiencing inconvenience.

Listed below are the main criteria to consider when purchasing an engraver.

Frequency of use

How often do you use the engraver? If you need to carry out work every day, then you need to buy the most reliable model. And for professional work, it is advisable to provide a power reserve of at least 250 W. This will make it possible to use low speed in work due to high torque.

Processed material

When choosing a tool, you need to consider what material you will be processing. Wood and glass products You can easily engrave or sand with a mini drill at a speed of about 20,000 rpm. Durable steel, high hardness alloys and gems It is better to process with a tool with a speed of 30,000 revolutions and the ability to adjust them. Otherwise, it is better to use an impact engraver.

When you decide for what purpose you will use the engraver, you need to decide on such characteristics as the weight of the tool, speed and power. On last stage Before purchasing, a selection is made based on the cost of the model, workmanship, ergonomics and noise level.

Engraver size and weight

Choose a tool of a size convenient for your purposes. Engravers are manufactured with minimal weight and size. Their small dimensions become possible only in the absence of a cooling system. As a result, the device heats up, and when using them, you must take a break from working after 10-15 minutes. This must be taken into account when purchasing a small device.

Engraver power

Engine power is very important when choosing an engraver. This characteristic affects the cost of using the tool and its price.

For use at home or in a small workshop, you need to purchase an engraver with a power of no more than 200 W and a speed of 20,000 rpm. Professional models produce a power of 250 W.

Shaft rotation speed

Also, when choosing a suitable tool, first consider the maximum and minimum shaft rotation speed. This characteristic is the most important for the quality of material processing. Polishing and grinding are performed at low engine speeds (otherwise the surface of the product may overheat). And cutting and sharpening of the tool is carried out at high speeds. Number of shaft revolutions per modern models within 15000-35000 rpm.

Check the possibility of adjusting the number of revolutions. Inquire about the presence of an engine speed controller. Good products equipped electronic adjustment, and cheap models are made with a device that simply reduces the motor voltage. Such tools cannot be used for high-precision work.

Engraver attachments

Find out how many different attachments are included in the kit, find out if there is a flexible shaft. Sometimes it is more profitable to purchase a high-quality engraver with a minimum of attachments, and, if necessary, acquire them gradually. This mainly depends on your wallet, the brand of the tool and the manufacturer of the device.

There are a huge number of varieties of special attachments. Among them there are devices with diamond coating, cutting wheels, polishing discs, and grinding devices. They process glass, metal alloys, stone, and other hard and soft materials.

Attachments for metal work. There are several varieties of such devices; they are made on the basis of high-speed steel or aluminum oxide. The shape is individual for different types of work, there are cone-shaped nozzles, spherical, round, cylindrical.

Metal bits for engraver

Diamond bits intended for processing hard metals, they are often made with
using diamond sputtering. To work on stone, nozzles made of silicon carbide are used. Dimensions and shape are the same as diamond tools, allow you to work with tiles, marble, glass.

Diamond engraver attachments

Nozzlesfor grinding material made of rubber interspersed with abrasive crumbs. There are felt rollers, they are used for polishing the material using a special paste, which is applied to a felt disc. The paste is sold separately or comes complete with polishing attachments. Attachments made from sandpaper allow you to work with metal products and wood. They sell abrasive grinding stones for processing ceramic, plastic and metal parts.

Sanding attachments

Usually the most popular attachments are included in the engraver kit. Replaceable attachments are secured using a small quick-release chuck (it makes it possible to quickly measure the working tool). The collet chuck requires more time when changing the nozzle, but in it the nozzle is precisely centered in the collet. For this reason collet chucks Optimal for precision operations. For different types For work, it is advisable to have both types of cartridges.

Additional accessories

The capabilities of small engravers have been expanded with the help of various additional components. Here are just some of them:

Angle nozzle necessary to perform work in inconvenient or hard to reach place, it can turn your engraver into an angle grinder;
Flexible shaft with a special bracket or vice makes it possible to work in comfort;
Special rack will turn your engraver into a drilling machine.

Engraver noise and vibration levels

Most device manufacturers do not indicate this characteristic in the model description, but you can turn it on and find out the level of its vibration and noise. Most often, medium-priced instruments have minor problems with noise; cheap and weak devices practically do not vibrate or make noise due to their low power, but in expensive instruments this deficiency is necessarily solved by the manufacturer. Please note that compared to the usual grinding machine and drill, the engraver makes very little noise.

Engraver cost

In most cases, close attention is paid to this point, but each person has his own cost-quality ratio. For one master it is more important to choose a productive and handy tool, while for others, brand awareness or, conversely, low price comes first.

By purchasing a device from a well-known manufacturer, you receive after-sales service (any tool can break) and the opportunity to read customer reviews. Here you need to understand that not everyone needs a multifunctional device at a high price - it depends on the purpose of use and the time of continuous operation. Remember that it is impossible to buy an instrument from well-known manufacturers inexpensively - if you find such an offer, then it is probably a fake (most often made in China).

Today we will introduce you to a small multi-tasking tool - a mini-drill, which goes by many names: engraver, grinder, drill, dremel. It received the latter name thanks to its inventor and founder of the company with his own name, Albert J. Dremel. As the names indicate, the range of work performed by this machine is infinitely large - it can cut pieces of material, make engravings, grind, polish, cut shaped grooves, make holes - and all this with amazing accuracy! For its versatility, accuracy, ease of operation and light weight, the mini-drill is popular among designers, jewelers, furniture makers, restorers, engravers, cosmetologists, as well as among handmakers.

Customer reviews:

Review #1: I am satisfied with the purchase. Works great, already tried it. Delivered directly to your home by courier. I recommend.

Review #2: I ordered it for a friend’s birthday, he had wanted such a device for a long time. The set is more than rich, the box arrived intact, delivery was fast. The Dremel holds speed, the cartridge does not hit, I thought it would be noisier. So far so good, time will tell.

Review #3: Excellent engraver. Works as it should. It gets a little warm at high speeds. The complete set arrived. Packed well, in a box, nothing fell apart. Delivery to St. Petersburg, super-fast in just 2 days. The seller is sociable, he told me everything, answered all my questions. In general, you can write for a long time, but it’s better to order and enjoy. In a word, I recommend it. Some positive emotions.

Review #1: The seller sent quickly! Well done! Well packed. Although the parcel got damaged along the way, it still arrived in order. The drill works - everything is fine! A small, convenient drill is a very useful thing, buy it with confidence and use it! Good luck to all!

Review #2: The machine itself is well made and feels good to hold in your hands. The size is smaller than I even expected. A handy flexible hose also works well. I took a tool for post-processing plastic and wood. I ordered it with a full set of extras so that I had something to start working with.

Review #3: Fast shipping, great packaging! Great respect to the seller! Sociable, friendly and focused on results and clients, THANK YOU! I took the maximum package. The Dremel itself is wonderful, it has enough power, but keep in mind that this is not a 750W drill))). Working with cutters is a little difficult. High minimum speeds, when polishing acrylic or plastic you will have to be especially careful. I RECOMMEND!!!
