Disc for concrete: the choice depends on the diameter and marking. Wheels for dry and wet cutting

The quality of tiling work depends on the tool. The times of a minimalist approach to tools are gone; today it is often impossible to carry out cladding at a decent level without having the appropriate tools. First of all, this aspect is important when cutting ceramics. The qualifications of the tiler and the outcome of tiling events are highly likely to be determined by looking at the tile cutting machine that the master uses. Glass cutters, scribers and even mechanical tile cutters do not guarantee high-quality cuts for many modern materials. Therefore, when striving for the perfect trim, pay attention to a power tool.

Even today, most wall ceramics can be done with a good old-fashioned scriber, while floor tiles can mostly be done with mechanical tile cutters. But what to do on an object that is complex, in terms of materials? The glass cutter does not cut porcelain tiles, and the “mechanics” almost always suffer from play. A professional tiler in modern realities is a specialist who has an electric tile cutter in his arsenal. On the path to professionalism, you need to understand what specialized power tools are available. Manufacturers offer:

• manual electric tile cutters;
• stationary with engine below;
• stationary with the engine at the top;

Manual electric tile cutters

The simplest type cutting tool powered by mains or batteries. The principle of operation is similar to an angle grinder, the differences lie in the “tile” specialization. Yes, it contains:

• comfortable handle;
• support sole;
• adjustment of the disk immersion depth and tilt angle;
• the ability to connect a dust collector or container with water (for wet cutting);

It is possible to work without dust in a horizontal position, so trim the laid wall tiles It won't work out completely. There are also larger variations that run on batteries. They no longer resemble a grinder, but they still don’t reach the title of machine tool. Their peculiarity is their compactness and independence from the network.

Universal manual electric saw MAKITA 4101RH with diamond blade. Power 860 W, rotation speed 12000 rpm. Possibility of wet cutting and tilt angle up to 45 degrees. Approximate cost - 23,000 rubles.

Trimming with a manual electric tile cutter high quality is not different. Their job is to replace the angle grinder and provide comfort and mobility.

Stationary machines with bottom-mounted motors

This one and next type The tool is united by the quality of the cut and the absence of dust - machines with water cooling, which at the same time prevents dirt from being sprayed. In all cases cutting material diamond disc protrudes. Here it is stationary, one part is above the platform on which the slabs are placed, the other is below, in a tank of water.

The “lower” orientation of the engine allows the machines to be made compact. This circumstance has led to widespread of this type. When carrying out renovations in a residential apartment, it is often difficult to find a place for a bulky tool, and transporting a “bottom-drive” tile cutter is much more convenient. But the main advantage of this type is the ability to cut dimensional tiles. There are no limiters on the support platform, which expands the format boundaries. The tiler is limited by skill and physical capabilities.

The disadvantage of such tools is the need to guide the ceramics along the cutting line manually. Certain skills allow you to do this without problems, but as the size of the tile increases, trimming becomes more difficult. The machines are equipped with guide rails that make it easier to fix the tiles, but comfortable cutting of large-format ceramics is limited by the frames of a small table.

Some models allow cutting at an angle of 45 degrees. The engine is stationary in any case, the platform tilts. The disks used in machines of this type are large (180-300 mm). However, the “tip of the iceberg” protrudes above the frame. The rest is left to the hydrocooling system. This circumstance entails a limitation on the cutting depth; usually the range is not impressive.

Let us summarize the advantages and disadvantages of the described type of tile cutters:

• compactness;
• increased slab format;

• narrow cutting depth range;
• insufficient cutting quality due to manual handling of slabs;

To ensure high-precision cuts and comfortable work, arm yourself with heavier weapons.

Stationary machines with overhead engine

This type of electric tile cutter - professional tool. It is not compact, relatively expensive and structurally complex. There are two types of “top-drive” water-cooled machines:

• Pavements. The cutting part is movable and moves along guides.
• Console. The platform is movable, the console is fixed.

We’ll leave it up to you to decide which type you prefer; there are as many opinions as there are people. The cantilever electric tile cutter is, in a sense, reminiscent of the machine from the previous section, the advantages and disadvantages of which you already know. The first type of tool is more common among tilers. Both types are characterized by:

• presence of a pump;
• possibility of cutting at an angle of 45 degrees;
• adjustable cutting height;
• the presence of clamps, guides and tires;

Pay special attention to all design details, the quality of the final work depends on them. More details about the main nodes below.

Chinese electric tile cutter Sturm tc9822u with top motor is suitable for cutting tiles, glass, marble, granite. Power 1.2 kW, rotation speed 2900 rpm. Maximum length cutting 920 mm, depth - 48 mm. The cost of such a device is 17-18 thousand rubles.

Manufacturer of tile cutter Corvette 468 – Russia (ENCOR). The line includes machines with both bottom-mounted and top-mounted motors. The maximum length and depth of cut are for the Corvette 468 tile cutter and are 920 and 60 mm, respectively. There are models with a laser pointer to make precise trimming easier. Russian machines are united by a durable body, stable design of moving parts and efficient electronic and hydraulic systems. approximate price this model - 28,000 rubles.

Characteristics related to the operation of power units

Rotational speed

High spindle speed does not play a significant role here. For cutting to be effective in terms of quality and quantity, a diamond blade needs 2-3 thousand revolutions per minute for Idling.

Engine power

This parameter is more important, and the more larger plate. Tile requires 750-1500 W, while granite and marble require a couple of kilowatts. The diameter of the diamond blade is directly related to the power: in the first case, the cut is provided with a diameter of 230-250 mm, in the second you will need a 350 mm wheel. The size of the machine also depends on the power; if you do not plan to work with stone, do not buy a unit that weighs over a hundred kilograms.

Cutting height

This is one of the most important factors. An electric tile cutter is purchased based on the expected thickness facing material. The mentioned 350 mm is enough to cut slabs up to 135 mm thick. A professional tiler who does not specialize in stone does not need such indicators. Working “on the edge” is not recommended due to possible overheating of the slabs, deterioration in the quality of the cut (chips, etc.) and jamming of the disk.

Typically, the cutting depth ranges from 40-110 mm, and in addition, the height is adjustable.

Electronics

An electric tool must be safe, so protection against current must be high. Especially in water-cooled systems. Despite the presence of RCDs, waterproof casings and high-quality insulation, many tile cutters require grounding.

Mechanical characteristics

bed

Depends on the dimensions of the platform maximum size cut tiles. Machines designed for cutting stone have impressive formats. The tile cutter's passport indicates the possible length of the cut, but in fact it is slightly less. By removing the clamps, you can increase the performance, but in this case, the ease of use decreases and the risks increase. In some models, the table is expanded due to support brackets or folding additional platforms.

Angle cutting capabilities

A professional electric tile cutter can cut at an angle of 45 degrees. However, some machines also offer intermediate angles. That and stability support system- one of the factors determining the quality of the machine.

Water supply

With water supply.

In machines of this type, water is supplied to the cutting area by a pump. Please pay attention to the following points:

• drainage efficiency;
• the amount of water circulation;
• availability of waste collection compartments;
• nozzle adjustment;

It is good to back up general principles with examples.

The conclusion of the review is subjective, but... In our opinion, the most convenient tile cutter is an electric one, with a top-oriented motor and a movable cutting part. Pay attention to all the details:

• comfort of system adjustment;
• ease of transportation;
• the ability to change the diameter of the disk;
• overview of the workspace;
• easy wheel replacement;
• cable quality and length;

The effectiveness of your work depends on the nuances. Practice first on training slabs, the skill of high-quality cutting will come very soon.

Diamond cutting blades have been designed to work with all stone-like materials: concrete, ceramic tiles, brick, natural and artificial stone.

The concrete disc is used as the working part of hand tools: grinders, wall chasers, concrete and asphalt gas cutters, as well as stationary stone-cutting machines. The most popular manufacturers of diamond wheels in the construction market are: Bosh, Cedima, Husqvarna, Dronco, Norton, Luga-Nova, etc.

Production, design features and purpose

This consumable material has the form of a metal disk, onto the edges of which diamond cutters are welded or soldered. These elements are produced from ground industrial diamonds and metal binder using the pressing method. The circle itself is made from a durable type of tool steel.

Note!
The main advantages of this material are its durability and high speed of work.
Diamond blades for cutting concrete are much more effective than their abrasive counterparts.
They remain sharp for a long time and provide the required cutting depth.

Making circles

1. Particles of industrial diamonds are pressed into special shapes into a metal binder (steel, titanium, various alloys). In this case, diamonds with different quality and sizes.
2. By varying the quality characteristics of diamonds, their concentration, binder components and disc shape, it is possible to produce discs of the desired brand.

1. The sectors are fixed to a metal base using laser welding (for dry cutting wheels) or soldering using silver (for wet cutting wheels).
2. Melting of silver is carried out at temperatures of 650/700°. This makes it possible to produce high-quality diamond segments.
3. At this stage cutting part The disk is a blank and cannot cut materials.
4. Next, each cutting wheel is sharpened.
5. Leading disk manufacturers have invented new technology fixation, which is called “HDS” (English – “high density sintred”), i.e. — powder soldering with a high degree of density. This method significantly increased the quality of disk segments. Similar wheels can be used for dry cutting.

This method eliminates the presence of a neutral zone between the body and the cutting sectors of the disk. This makes it possible to use the working part of the circle 100%. Similar products are marked “With - HDS technology”.

1. To ensure effective work, the cutting edges of the wheel are sharpened with ceramic sharpeners. This is done so that the first diamond particles are visible.
2. The product is now ready for use.
3. The direction of the factory opening of the disk determines its position on the tool shaft. Leading manufacturers do the right thing by indicating the direction of movement of the circle with arrows on it.

Product Types

1. Segment wheels for dry cutting. On their body, the incisors are arranged in sectors. There are slits between them. They serve to relieve stress on the incisors, better remove heat and work waste, and linearly expand the disc.

Note!
Technological slots can end in radius with borings.
They more effectively redistribute shock-type loads during operation, relieving overstresses on the wheel body.

1. Solid discs(without segmentation of the working edge) for the wet type of cutting. They may have holes along their radius to evenly distribute the stresses occurring in the cutting part. When using such products, it is necessary to supply water as a coolant.

1. Cutting reinforced concrete with diamond wheels is carried out with special discs. To cut without problems reinforced material, they have an increased body thickness and a higher content of diamond particles in the teeth.

1. Grinding wheels, as their name suggests, are needed for grinding stone-like surfaces. The abrasive diamond layer on them is applied to the annular skirt (“cup”) protruding along the edge of the disk.

Product marking

Disc markings indicate their three characteristics (in millimeters):

• working diameter;
• cutting width;
• diameter of the hole for mounting on the tool.

For example, "Cedima" DC/D 150-22-3 UP.

Here:

• 150 mm – the diameter of the disk itself (it also guides the depth of the cut);
• 22 mm – diameter of the mounting hole;
• cutting width – 3 mm.

As a rule, the designation of the width of the cut is marketing ploy. The manufacturer thereby makes it clear that his disk for cutting reinforced concrete is wider, and therefore stronger. This has nothing to do with the real state of affairs.

Circle sizes

The table shows the range of sizes of segmental cutting discs for concrete, according to State Standard No. 10110-87

Disc diameter in mm	100	125	150	175	200	250	300	350	400	450	500
Width of cutting part min./max., mm	0.451	0.451.2	0.451.5	0.601.5	0.802.2	1.52.2	1.52.2	1.52.2	1.92.2	2.4	2.4

1. There are also circles with a diameter of 50 mm, 75 and 90. However, they are almost never used for cutting concrete.
2. Discs with diameters greater than 600 mm are also produced. However, they are not used in construction, but for the production of building materials, for example, granite and marble slabs.
3. Some manufacturers, both foreign and ours, produce circles with non-standard dimensions, for example, 115 mm and 230. State standard The variety of disk sizes is not strictly regulated. Therefore, the use of such circles and their mention in technical documentation during construction is quite acceptable.

Using disks

1. Circles with a diameter of 125 mm are most in demand for cutting concrete when renovating premises.
2. Analogues with sizes of 150/230 mm are used for processing concrete elements, for example, lintels in openings, slopes. They are always needed in panel buildings.
3. The instructions recommend using diamond wheels with a diameter of 350 mm and 400 for working with large concrete products, foundation blocks. Such discs are usually used in stone-cutting machines or units for chipping stone-like surfaces.

How to choose a drive

To correctly select a disk, you need to know what diameter, shape of segments and brand of wheel are suitable for the tool used and the material to be cut.

Circle diameter

1. The outer size of the wheel affects the cutting depth. Therefore, the deeper the cuts are needed, the larger the disc diameter must be chosen. In this case, you should take into account the range of wheel sizes provided for your tool.

Note!
It is prohibited to use consumables not intended for this unit.
The linear value of the wheel speed will be too low or too high (depending on the material being processed).
Therefore, the disk will wear unevenly or overheat and become stuck.
In addition, there is a risk of overloading the tool and breaking it.

1. The inner diameter of the disk should be selected with your own hands, looking at the shaft of the unit. There shouldn't be a gap. The difference in diameters can be leveled out by accurately selecting washers.

Below are the most common internal disc hole sizes.

1. Dry cutting wheels with a diameter of 115/230 mm are designed for hand-held angle grinders (grinders) and have an internal hole of 22.2 mm.
2. Analogues with dimensions of 150/350 mm are suitable for portable wet cutting stone cutting machines and have an internal diameter of 25.4 and 30 mm.

1. Circles with dimensions of 300/400 mm are suitable for hand-held petrol cutters; they have an internal hole of 25.4 mm. Can be used for dry and wet sawing.
2. Analogues measuring 500 mm or more are intended for large stationary stone-cutting machines. They have inner diameter 60 mm. They perform wet cutting.

What does the label say?

1. When it is necessary to constantly cut various stone-like materials, it is best to choose a universal brand of blade. If the material is the same, and it is known in advance, it is better to choose a specialized wheel.
2. I must say that different manufacturers used for marking various methods, symbols and instructions. Based on this, when choosing a circle, you should be extremely careful. Otherwise, the cutting cost will be unnecessarily high.
3. It is clear that soft materials are easy to process, but hard analogues are difficult to process. Therefore, for lightweight concrete with a soft filler (expanded clay, slag) or a cellular analogue, discs with rigid ligaments should be selected. For materials with hard fillers (gravel, granite crushed stone), wheels with soft bonds are suitable.

Which circle to buy: for dry or wet cutting

1. The laser-welded blade is designed for dry cutting and is also suitable for wet sawing. Provided that the design of the instrument allows such an opportunity. Nothing critical will happen to the circle. However, the speed of operation and service life consumables will go down.
2. Discs designed for wet cutting of concrete, as a rule, have a larger diameter than their counterparts for dry work. They require constant water cooling. The temperature of their body must remain within the permitted values. In addition, you need to periodically remove particles of the processed material from the cut.

Note!
It is strictly prohibited to carry out dry work with circles for wet cutting.
Silver solder melts at a temperature of +650°, so the teeth fixed by it can fall off from the body of the circle.
The disk itself can also heat up, lose its rigidity and begin to wobble.

Before purchasing a disc, please find out the following:

• what type of concrete needs to be cut;
• what will be the cutting depth;
• diamond wheel, what dimensions are suitable for the tool used (its outer and inner diameter, as well as thickness, are important);
• what is the power (in kilowatts) of the cutting unit;
• what cutting method will be used: wet or dry (this depends on the design of the tool).

Provide all this information to the sales consultant, and he will select you best option products.

If you have already purchased a circle, make sure that it is intended for the type of concrete that will be cut.

1. When placing a circle in the tool, determine whether the direction of its rotation, shown on the body by an arrow, coincides with the direction rotational movements shaft
2. The unit speed should be similar to the value indicated on the disk. On the label, manufacturers write the maximum permitted rotation speed (revolutions per minute) and the maximum permissible linear speed (meters per second).
3. If you operate at the wrong speed, you may damage or wear the wheel unevenly. And cutting will be ineffective.
4. Do not tilt the disk to the sides and do not use muscle force (the weight of the tool is quite enough).
5. If the cutting depth is large, make a preliminary cut (1/5 of the entire cutting size). This way you will prevent overloading of the unit, and it will be easier to get an even cut.
   
6. During processing hand tools concrete slabs having a thickness of 2/4 cm, place the limiter on the disk on greatest depth sawing. This way there will be minimal contact with the material. The same preparation is needed if diamond drilling of holes in concrete is performed.

Conclusion

By choosing the right cutting disc for stone-like material, you will ensure high efficiency. In this case, you should take into account both the brand of the circle and the characteristics of the concrete. The video in this article contains a lot of additional information.

In order to save budget when laying tiles in an apartment or private house, many people prefer to carry out all the work themselves, especially since there are more than enough instructions for carrying out such work. If everything is clear with the choice of design and purchasing the material, then difficulties often arise with the installation process, since any room when tiling will require trimming the tiles and adjusting them for an aesthetic appearance. Often used at home for cutting ordinary grinder, but not everyone knows what kind of disc is needed for cutting ceramic tiles or porcelain stoneware.

The market offers a large number of different circles, the price of which varies from 900 to 25,000 rubles. In order not to pay extra money for a certain brand and at the same time not to buy a useless blank, you need to find out what types of products exist, what can be cut with them and in what quantities.

Types of discs for cutting porcelain stoneware and ceramic tiles

Many people go to the store and try to buy a disc for cutting tiles or porcelain tiles, believing that these are two different circles. In fact, the disc is selected not so much based on the type of cutting material, but also taking into account the volume of cutting and the tool itself that will be used for cutting. All available samples can be divided into three main types; then we will consider each of them in detail.

Wet cutting wheels

The photo shows a diamond blade for porcelain tiles for wet cutting, also called solid. These same discs can also be used for cutting tiles in small quantities. The product is intended for wet cutting, that is, in the presence of coolant. Suitable for electric tile cutters and, thanks to the continuous cutting edge, can cut perfectly straight cut almost without chips.

With water cooling, cutting time is virtually unlimited, which is ideal for cutting large porcelain tiles or floor tiles, as well as for working with large volumes.

For your information. Such circles can also be used when working with an angle grinder, but only for small cuts and only on tiles. In this case, the duration of the circle's operation should not exceed 10-15 seconds, after which it needs to idle for 20-30 seconds to cool.

Diamond chips are applied to the cutting surface of the disc using silver solder, which when heated loses its strength and the coating quickly wears out.

Important. Many people often make the mistake of immediately after cutting the tiles with a grinder, they lower the solid disk into a bath of water to cool. Rapid cooling leads to the appearance of microcracks in the coating and the product itself. The result of such actions are chips on the body of the circle, which often fly off during cutting and can damage equipment, tiles and injure a person.

Dry cutting wheels or dry cutters

A disk for dry cutting porcelain stoneware or tiles is called a segmented disk or dry cutter. The product does not require water cooling, since it has structural cutouts from the edge to the center. These cutouts divide the edge of the circle into segments, serve to cool the product during operation and compensate for the expansion of the metal when heated.

Designed to work at low speeds, ideal for an angle grinder or circular saw. It is recommended to use a dry saw for cutting porcelain stoneware or floor tiles large thickness. Suitable for small to medium-sized jobs, but will leave chips on glossy or glazed tile surfaces.

The photo below clearly demonstrates the result. The topmost slab is the result of cutting with a dry segmented disc, the lower slabs are cut solid with a coolant supply. Such chips are acceptable if the joints are hidden, but on a visible area of ​​the floor, such quality of cutting is not acceptable and they can only be hidden with a single-color grout matching the color of the material.

For your information. Like the wet cutting disc, the dry saw also needs cooling. The cutting time is about 1 minute, after which the wheel cools at idle for 20-30 seconds and you can start cutting again.

Important! It is dry cutters that cause injuries when safety precautions are not followed. The disc segments can catch the thread of a knitted glove, so it is recommended to use mittens made of thick fabric. It is necessary to carefully monitor the position of the circle when cutting; its slight displacement leads to damage to the disc and the working surface.

Combined

Combined circles are a combination of a solid disc and a dry cutter. This universal product is perfect choice for domestic use, since it can work both in dry and in coolant mode. The advantage of the product's versatility is also its disadvantage. The disk can't do that. clean cut as a solid analog and cannot work for a long time without cooling like a typical dry cutter.

Advice! For occasional use in an apartment or private house, when laying tiles or porcelain tiles in small rooms with a minimum number of cuts, we recommend choosing a combination disc.

Important! Combined models suffer more than others from the clogging effect, when small grains of tiles become clogged in the grooves and are soldered into the diamond coating. On other types of disks, this problem can be solved by turning the disk over and changing the direction of rotation on the axis. Reverse rotation cleans the coating and restores cutting ability. Combined models usually have a given direction of rotation and it is impossible to turn it over to the other side, it simply will not cut. In this case, use normal sand-lime brick or concrete, make a few cuts and the spray will come off.

What determines the price of a circle?

The cost of discs largely depends on the manufacturer, the size of the circle and its type. Most well-known manufacturers quality discs are brands such as:

• Bosch
• Distar
• DeWALT
• Dronco
• Emar Vollrand
• HILTI
• Norton
• Kronenflex

Among domestic producers It is worth highlighting the following:

• LugaNova
• Interskol
• Practice

It's obvious that foreign manufacturers will cost more than domestic ones due to markup for the cost of the brand and transportation. According to the results of independent testing of well-known manufacturers on the market, it was the ZUBR that showed results that significantly exceed the performance of foreign models.

The technology of spraying diamond abrasive onto the disc also affects the price of the disc. cutting edge. The most common technologies are:

• Soldering. We mentioned these products above, where abrasive shavings are soldered to the edge with silver solder. The technology is cheap and allows you to reduce the cost of models, however, when heated, the solder loses its quality and the diamond coating quickly wears out. Consequently, the service life of the circle is short, but quite suitable for domestic use.
• Geometric closure. In this method, electricity is used to heat the edge as much as possible and diamond sand is firmly soldered into the surface of the wheel. The service life of such products is significantly longer than previous ones, and the price still remains within the range of affordability. Typically, this method is used for combination wheels that are suitable for dry and wet cutting.
• Laser soldering. This is a very expensive technology and is reserved for industrial use models. With this circle you can cut everything from white brick and ending with granite. The price of the product varies from 9,000 to 25,000 rubles.

Important! Today the market is filled with outright fakes. famous brands, so when buying a disc for dry cutting porcelain stoneware or tiles, pay attention to the price. For example, a circle from the manufacturer Bosch or HILTI cannot possibly cost 900-1200 rubles. Make purchases only at specialized retail outlets or brand offices.

How to choose the right disk

Based on the above information, we can already select diamond blades for cutting ceramic tiles and porcelain stoneware based on our needs. The basic selection rules are as follows:

• If you need to cut porcelain stoneware or there is a large amount of work to be done without the ability to supply coolant to the cut, then it is better to give preference to segmented dry cutters with deep slots or holes for air cooling.
• If you need to work normally ceramic tiles(not floor) with a glaze coating, then we choose solid cutters with diamond coating for wet cutting. It is advisable that the thickness of the circle does not exceed 2 mm to reduce the number of chips.

Advice! To make the cut as even as possible, choose a solid disk with a spray strip slightly larger than the thickness of the tile itself. It is advisable to soak the tiles in water before cutting; this is not required for porcelain tiles.

Today I would like to talk about grinder blades, which are best used for sawing both tiles and porcelain stoneware. This video is primarily not intended for professionals; they, in general, have known all this for a long time. And for those people who are planning to decorate a bathroom or toilet on their own, they don’t have any tile cutters or some kind of crowns to drill some holes in ceramics or porcelain tiles, but they do have an angle grinder. And they can buy a disc that will cut porcelain tiles and tiles without chipping.

Also, these discs are very good for doing how not to large holes, and there are also large holes in the tiles without any chips or scuffs. It is very good to use them to cut out both “U-shaped” and “L-shaped” structures in tiles, when all this is cut very close to the edges, where literally 1.5-2-3 centimeters remain to the edge. And if the wrong disc is used, then, as a rule, the tiles and porcelain tiles break in this place.

"Wet cut" and turbo disc

Now I’ll bring the camera closer and show you what disks I currently have in stock. Now I have two disks available. This disc that comes with notches is usually called a turbo disc or a disc for fast cutting.

And here is this disk, which is absolutely smooth and only has diamond coating along the edge. This disc is usually sold in stores and will say "Wet Cut" on it.

There are also discs similar to this “wet cut”, but it will also have slots like this along the entire contour. As a rule, it is written “dry cut”. It is best to cut tiles and porcelain tiles with a disc that says “wet cut.”

On this disk, if you see it like this, it says “wet diamond cutting.”

On this disc there is a turbo inscription. It's already erased here, but you can read it.

It is best to cut tiles with such discs. I haven't used them before. I was confused by the fact that it says “wet cut”. I always thought that you could somehow cut with water or something else. But after trying it once, I realized that even without water it can successfully cut ceramics and porcelain stoneware.

This disk contains such soldering and fastenings.

They begin to hit the enamel and chip the enamel. The same goes for dry cuts where the slots are located. These slits also hit the enamel and cause chips. And if you cut along the very edge. Let's say you need to make some kind of “U-shaped” cutout from this edge.

So, as a rule, this edge here will definitely break off if you use either a turbo disk or a “dry cutting” disk. Since it will hit the tile itself, there will be strong vibrations and the edge will definitely break off, and nothing will work out for you. What does not happen when sawing with a “wet cut” disc.

“Wet cut” what is it intended for? Let's say that in a tile cutter such discs stand crosswise, like this.

And they seem to pass through the entire array of tiles, and there I agree, water is needed. With a grinder you will cut only the very best, with an edge like this. So that this disk somehow heats up or overheats, and it becomes jammed in the tile. Well, this is hardly possible, and is unlikely to happen.

The only disadvantage of a wet cutter when sawing with such discs is that the room is very dusty. That is, if you do all this in an apartment, you will have to go out onto the balcony. And if you do this in a private house, you will have to go out. Do all this marking in the room, and go outside to cut.

Real example of disk operation

Now I will go outside and demonstrate the quality of cutting with a turbo disc, and the quality of cutting with a “wet cut”.

First, I'll try to do all this with a turbo disk.

Now I’ll try to use a “dry cut”.

This is the cut with a turbo disc.

And this is a “wet cut” cut

A “wet cut” will be of better quality. Although it is porcelain tile, it is difficult to saw. Chips, no matter what, scuffs. There are chips, of course. Now I’ll try to do the same on regular tiles.

Here's the usual one tile wall

Now I will cut it with a “wet cut”, then turbo.

Here is the “wet cut”

On this side, turbo-res.

“Wet cut”, as you can see, is of higher quality, almost completely free of chips and burrs.

Of course, someone will say that the difference in cuts is insignificant, there is almost none there. To some extent, when longitudinal cuts are carefully cut and a normal balanced grinder is used, then this is so. “Wet cutting” is also valuable because these holes for the sewer, for the 110 pipe, are very close to the edges.

That is, on this side there are 1-1.5 centimeters, on this side 2.5 remain. This is the hole I cut with a “wet cut”. If I started cutting with a turbo disc, then this or this edge, well, tile (it was porcelain tile on the floors), it would still break. And “wet cutting” does not cause vibration on the tile and therefore the tile is cut normally and does not break. The same applies to cuts if the letter “P” or the letter “G” is somewhere very, very close to the edges.

I hope this video was useful to someone. Buy discs that say “wet cut.” And when cutting tiles and porcelain stoneware, you will always have luck. Especially if you cut out any holes or anything else very close to the edges.

For diamond cutting building structures Two methods are used - “wet” and “dry”. The difference between these types of work is quite simple - wet diamond cutting implies the constant or periodic use of water to cool the working body. Dry diamond cutting does not require the use of liquid in the working process. It would seem that the difference is not great, but in practice it is quite significant. Let's look at it in detail.

Advantages of wet diamond cutting

• increasing the resource intensity of the cutting element due to timely cooling;
• improving the quality of work performed in conditions of high-precision work;
• reduction of dust levels due to the absorption of dust particles by a water jet (scrubber principle);
• the ability to work with concrete at a depth of over 60 mm, with brick at a depth of over 84 mm;
• reducing the duration of work due to the continuity of the work cycle;
• minimizing noise and operating vibrations of the cutting tool, because diamond drilling (drilling) takes place in conjunction with the timely removal of fragments and dust from under the cutting element with a stream of water;
• high efficiency of work due to the high speed of their implementation and the continuity of the technological cycle.

The advantages of the wet cutting method come at the cost of some additional difficulties.

Requirements of Wet Diamond Cutting

• mandatory availability of water in sufficient quantities:
  when working with high loads this can be a water supply system, a large reservoir or a natural reservoir (any source, including a water supply system, must be located at a distance of up to 50 m); for a certain amount of work, a pressure of up to 10 liters per minute is required;
  when performing one-time work with moderate load a small container of water or a tank with a water pump is enough for a diamond element;
• deletion process water and sludge from the workplace using industrial vacuum cleaners;
• control over water leakage into openings and crevices of the building (as appropriate);
• control over the ingress of water onto live elements and power supply devices;
• need to attract additional employee to control the water supply to the diamond disc;

Advantages of dry diamond cutting

• work opportunity portable tool away from a water source;
• ability to work alone;

Disadvantages of dry diamond cutting

• high dust content of the workplace and adjacent premises; The use of vacuum cleaners reduces dust, but does not get rid of it completely
• lower level of accuracy and quality of work compared to wet diamond cutting.
• inability to work with maximum load and productivity due to the rapid heating of the diamond segment, which leads to a decrease in its resource intensity and rapid failure;
• limitation of cutting depth to 60 mm (for concrete) and 85 mm (for brick);
• impossibility quick removal construction waste from under the cutting body, which increases the duration of the cutting process, increases the level of noise and vibration;

Thus, wet cutting is the preferred method, although its use is associated with additional efforts to organize work, namely, you need to take care of the supply and removal of water. However, if we are talking about a sufficient amount of work, then the additional effort to supply water is not so burdensome in comparison with the costs of the dry cutting method. In other words, it is easier to take care of the supply and removal of water than to carry out cutting at the cost of great effort and time.

Generally wet method diamond cutting is more preferable, therefore it is always used where large volumes of work, high depth and precision of diamond cutting are required.

Dry diamond cutting makes practical sense when manual work, which do not require the highest level precision and deep cuts. Or on an exceptional basis: if it is simply impossible to ensure sufficient water supply.
