Diamond tools, by which, as a rule, they mean diamond discs, have wide application in construction. Its popularity is due to a number of advantages unique to it. Work with this tool, unlike perforating and breaking equipment, occurs without much noise and vibration, which preserves the integrity of the structures and does not irritate the ear. The surface of the holes cut with a diamond tool is smooth and even, does not require cleaning and grinding.

Diamond blades are used for cutting materials such as ceramic or clinker tiles, reinforced concrete, brick or cinder block, slate, asbestos cement, asphalt and other similar materials. It is diamond discs that allow you to process stone and concrete quickly, accurately and with the minimum possible wear of the disc itself.

A diamond tool consists of two main elements: a steel body and a segment saturated with diamonds. The method of fastening the latter may have different variants: Segmented edge, solid edge, serrated edge, or solid segment that is integral with the blade body.

A diamond tool, properly matched to the material to be machined, has an optimal balance between diamond performance and bond abrasion; the diamond is held until fracture, then a new crystal is exposed. It is on this balance that the quality and life of the diamond tool depends.

Disc working surface

The working surface of a diamond disc can be either solid or segmented. The segmental surface is necessary to remove small particles of the processed material from the cut, which have an abrasive effect on the working surface of the diamond blade and can significantly reduce its service life.

The body of the disc is a plate made of specially processed and hardened steel of very high quality. Typically, the segments are located on the teeth, between which there are depressions. They are also called slots. They help cool the blade while cutting by allowing water (wet cutting) or air (dry cutting) to pass between the segments. They also allow the blade to flex to a certain extent when cutting. The segments consist of a sintered mixture of diamonds and metal powder.

The segment or segmented edge is slightly wider than the body, so that when the cutting edge penetrates the material, there is practically no wear on the steel.

Surface spraying

It should be noted that if the coating of the working surface of the diamond disc has worn off, it will have to be replaced. It is diamond coating that has a cutting effect on stone or concrete; without it, the steel disk will grind much more than the surface to be treated.

The principle of operation of the diamond disc

1. The diamond tool does not cut, but crushes the material being processed with diamond crystals. The metal bond keeps the crystals from falling out. In the process of work, diamonds are also supported by "comet tails" that appear directly behind the crystals and enhance the holding effect of the bond.

2. Diamonds exposed in this way cut into the material, turning it into fine dust.

3. During cutting, exposed diamonds may crack or break (the faster, the harder and denser the material being cut).

4. At the same time, abrasive wear of the metal bond of the segments begins with the material being processed.

Dry and wet cutting

According to the sawing method, diamond blades are distinguished for dry and wet cutting.

dry cut

When dry cutting, the diamond blade is attached to a tool, such as an angle grinder (or angle grinder) or a gas cutter, just like conventional cutting discs. Wet cutting involves the presence of specialized stationary or portable equipment, which, during the sawing process, supplies water or other liquid to the cutting site. Wet cutting is used, for example, when working with asphalt, similar road equipment fitted with large discs.

Wet cut

Wet cutting with a diamond blade allows you to achieve an accurate and very accurate cut in hard and at the same time fragile materials such as ceramic tiles, marble or glass. In this case, there is no delamination of materials like marble, thanks to high precision cutting with diamond discs.

The choice of sawing method may depend on the preferences of the user or on some specific restrictions associated with the work being done.

When working on concrete, wet cutting is preferred, as it cools the tool, which allows for greater depth of cut and longer tool life. In the case of stone cutters and tile cutters, both wet and dry cutting tools can be used equally well. General purpose cutters on the job site most often use dry cutting tools.

Wet cutting is mainly used to reduce dust and to cool the tool. If runout occurs when dry cutting with powerful hand cutters, try wet cutting. This will cool the cutting disc, which helps to eliminate this problem. Dry cutting tools can be used with or without water supply, depending on the machine used and the material to be cut.

Choosing a diamond blade

For right choice diamond blade, it is necessary to take into account which cutting machine will be used and what material needs to be processed. To carry out diamond cutting to a greater depth, a diamond blade of the appropriate diameter should be selected. In this case, the selected diameter of the diamond blade must be suitable for the cutting machine.

Also, when choosing a diamond blade, one must take into account the size of the inner hole - it must correspond to the diameter of the shaft of the cutting machine. Gaps between the shaft and the inner hole of the disk are not allowed.

Depending on the type of material being processed, the shape of the teeth of the diamond blade is selected. This choice will affect the purity and processing speed. For some soft materials, diamond blades without teeth may be used to prevent damage to such materials.

Even before buying a diamond disc, you need to clarify a few questions for yourself in order to be well versed in choosing a brand of disc. Below are the main points to take into account:

• processed material;
• Specifications and capabilities of the cutting machine used;
• Required cutting depth;
• Type of cutting.

Disc Installation

The diamond blade must be properly installed on the cutting machine. Correct installation implies that the direction of rotation of the machine shaft will coincide with the direction of rotation of the diamond blade, provided by the manufacturer and indicated by an arrow on the body. In some cases, the arrow on the body may be missing, then you need to refer to the documentation before starting diamond cutting. In addition, the rotation speed of the machine shaft must match the allowable rotation speed of the diamond blade. For each brand of diamond blade, the maximum allowable rotation speed may not be the same, and to find out the allowable rotation speed of the disk, one must also refer to the documentation.

Incorrect installation and incorrect use of the diamond blade can not only reduce cutting efficiency, but also cause damage to the cutter over time.

Before purchasing a diamond blade, get comprehensive information about the characteristics of the purchased equipment!

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 involves the constant or periodic use of water to cool the working body. Dry diamond cutting does not require the use of liquid in the workflow. It would seem that the difference is not great, but in practice it is quite significant. Let's analyze it in detail.

Benefits of wet diamond cutting

• increasing the resource intensity of the cutting body due to timely cooling;
• improving the quality of work performed in the conditions of work of a high level of accuracy;
• dust reduction due to the absorption of dust particles by the water jet (scrubber principle);
• the ability to work with concrete at a depth of more than 60 mm, with brick - at a depth of more than 84 mm;
• reduction of the period of work performed due to the continuity of the work cycle;
• minimization of noise and operating vibrations cutting tool, because diamond drilling (drilling) takes place in conjunction with the timely removal of fragments and dust from under the cutting body with a jet of water;
• high cost-effectiveness of work due to the high speed of their implementation and the continuity of the technological cycle.

The benefits of wet cutting come at the cost of some additional complexity.

Wet diamond cutting requirements

• the presence of sufficient water is mandatory:
  when working with a high load it can be a water supply system, a large reservoir or a natural reservoir (any source, including a water supply system, must be at a distance of up to 50 m) with a certain amount of work, a pressure of up to 10 liters per minute is needed;
  when performing one-time work with a moderate load a small container with water or a tank with a water pump is enough for a diamond element;
• removal of industrial water and sludge from the workplace using industrial vacuum cleaners;
• control over water leakage into openings and crevices of the building (according to the situation);
• control over the non-ingress of water on current-carrying elements and on power supply devices;
• the need to attract an additional worker to control the supply of water to the diamond disk;

Benefits of dry diamond cutting

• the ability to work with a portable tool away from a water source;
• the possibility of working 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 completely eliminate it
• lower, compared to wet diamond cutting, the level of accuracy and quality of work.
• the impossibility of working with the maximum degree of load and productivity due to the rapid heating of the diamond segment, which leads to a decrease in its resource intensity and rapid failure;
• limiting the cutting depth to 60 mm (for concrete) and 85 mm (for brick);
• impossibility quick removal construction debris from under the cutting body, which increases the duration of the cutting process, increases the level of noise and vibration;

In this way, 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 it is a sufficient amount of work, then the additional effort to supply water is not as burdensome compared to 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 cut at the cost of great effort and time.

In general, the wet method of diamond cutting is more preferable, therefore it is always used where large amounts of work, high depth and accuracy of the diamond cut are required.

Dry diamond cutting has practical sense at manual work, which do not require the highest level precision and deep cutting. Or according to an exceptional principle: if it is simply impossible to provide sufficient water supply.

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

It is also very good to do these discs as not big holes, that and large holes in the tile, too, without any chips, burrs. It is very good to cut out both “U-shaped” and “L-shaped” structures in a tile with them, when all this is cut very close to the edges, where literally 1.5-2-3 centimeters remain to the edge. And if the disk is not used the one you need, then, as a rule, tiles and porcelain tiles break in this place.

Wet cut and turbo disc

Now I will bring the camera closer and show what discs I currently have available. I currently have two disks. This disc here that comes with notches, it is usually called a turbo disc or a fast cutting disc.

But this disk, which is absolutely smooth and has only a coating on the edge, diamond coating. This disc is usually sold in stores and will be labeled "Wet Cut".

There are also discs similar to this “wet cut”, but it will still have such cuts along the entire contour. As a rule, “dry cut” is written on it. It is best to cut tiles and porcelain stoneware with a disk on which “wet cut” will be written.

Here on this disc, if you see it like this, it just says “wet cut diamond cutting”.

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

It is best to cut tiles with such disks. I didn't use them before. I was confused by the fact that it says "wet cut". I always thought that you can somehow cut with water or something else. But having tried once, I realized that even without water they can successfully cut both ceramics and porcelain stoneware.

On this disk there are such solderings and fastenings.

They begin to hit the enamel and chip the enamel. The same on a dry cut, where the slots are. These cuts also hit the enamel and make chips. And if you cut along the very edge. Let's say you need to make some kind of cutout from this edge "U-shaped".

So, as a rule, this edge will definitely break off if you use either a turbo disc or a “dry cut” disc. Since it will hit the tile itself, there will be strong vibrations and the edge will definitely break off, and you will not succeed. What does not happen when sawing with a “wet cut” blade.

"Wet cut" what is it for? Let's say in a tile cutter such disks stand across, like this.

And they pass, as it were, through the entire array of tiles, and there I agree that water is needed. With a grinder, you will cut only the very best, just such an edge. So that this disk somehow heats up or overheats, and it gets stuck in the tile. Well, that's hardly possible, and unlikely to happen.

The only disadvantage of a wet cutter, when sawing with such discs, is the high dustiness of the room. That is, if you do all this in an apartment, you will have to go out to the balcony. And if you do it in a private house, you will have to go out. Do all this marking in the room, and go out to saw on the street.

A real example of how disks work

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

To begin with, I will try to do all this with a turbo disk.

Now I'll try to put a "dry cut".

This is the cut with a turbo disk.

But this is the cut "wet cut"

"Wet cut" will be of better quality. Although it is porcelain stoneware, it is difficult to cut. Chips, all the same, some-not-what, badass. There are chips, of course. Now I will try to do the same on a regular tile.

Here is a regular wall tile.

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

Here is the "wet cut"

This side is turbo-cut.

“Wet cut”, as you can see, is of better quality, almost completely without chips and scuffs.

Someone, of course, will say that the difference in cuts is insignificant, there is almost none there. To some extent, when longitudinal cuts are neatly cut and a normal balanced grinder, then this is so. The “wet cut” is also valuable because these holes for the sewer, for a 110 pipe, it is very close to the edges.

That is, from this side 1-1.5 centimeters, from this side 2.5 remains. This is the hole I cut with a “wet cut”. If I started cutting with a turbo disc, then this or that edge of, well, tile (it was porcelain stoneware on the floors) it would still break. A “wet cut” does not give vibration to 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 helpful for someone. Buy discs that say "wet cut". And when cutting tiles and porcelain stoneware, you will always be lucky. Especially if you will cut out some holes or something else very close to the edges.

Cutting diamond blades have been developed to work with all stone-like materials: concrete, ceramic tiles, brick, natural and artificial stone.

A disc for concrete is used as a working part of a hand tool: grinders, wall chasers, concrete and asphalt petrol cutters, as well as stationary stone-cutting machines. On the construction market The most popular manufacturers of diamond wheels are Bosch, Cedima, Husqvarna, Dronco, Norton, Luga-Nova, etc.

Production, design features and purpose

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

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

Making circles

1. Particles of industrial diamonds are pressed into special shapes in binder metal (steel, titanium, various alloys). In this case, diamonds are used that have different quality and sizes.
2. By varying the quality characteristics of diamonds, their concentration, the components of the binder and the shape of the disk, it is possible to produce disks of the desired grade.

1. The sectors are fixed on a metal base by laser welding (for dry cutting wheels) or silver soldering (for wet cutting wheels).
2. The melting of silver is carried out at a temperature regime of 650/700 °. This makes it possible to produce high quality diamond segments.
3. At this stage, the cutting part of the disk is a blank, and cannot cut materials.
4. Further, each cutting wheel is sharpened.
5. Leading disc 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 circles 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 by 100%. Such 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. Now the product is ready for use.
3. The direction of the factory opening of the disk determines its position on the tool shaft. Leading manufacturers are doing the right thing by indicating the direction of the circle with arrows on it.

Product types

1. Segment discs for dry cutting. On their body, the incisors are arranged in sectors. There are slits between them. They serve to relieve tension incisors, better heat and waste removal, linear expansion of the disc.

Note!
Technological slots can end with bores along the radius.
They more effectively redistribute impact-type loads during operation, relieving overvoltage of the wheel body.

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

1. Cutting reinforced concrete with diamond wheels is carried out with special discs. In order to cut reinforced material without problems, they have an increased body thickness and more content diamond particles in teeth.

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

Product marking

Disc markings announce three of their characteristics (in millimeters):

• working diameter;
• cutting width;
• tool hole diameter.

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

Here:

• 150 mm - the diameter of the disk itself (it also orients to 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 a marketing ploy. The manufacturer thereby makes it clear that his disc for cutting reinforced concrete is wider, therefore stronger. It has nothing to do with the real state of things.

Circle sizes

The table shows the range of sizes of cutting segment 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 the cutting part min./max., in 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 of more than 600 mm are also produced. However, they are not used in construction, but for the manufacture of building materials, for example, granite slabs, marble.
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 rigidly regulated. Therefore, the use of such circles and their mention in the technical documentation during construction is quite acceptable.

Disk Usage

1. Circles with a diameter of 125 mm are most in demand for cutting concrete in the repair of premises.
2. Analogues with a size of 150/230 mm are used for processing concrete elements, for example, jumpers in openings, slopes. They are always needed in panel buildings.
3. Diamond wheels with a diameter of 350 mm and 400, the instruction recommends using for work with large concrete products, foundation blocks. Such discs are usually used in stone-cutting machines or aggregates for chasing stone-like surfaces.

How to choose a disk

In order to correctly select a disc, you need to know what diameter, shape of the segments and brand of the circle are suitable for the tool used and the material to be cut.

Circle diameter

1. The outer size of the circle affects the depth of cut. Therefore, the deeper the cuts are needed, the larger the diameter of the disc must be selected. In this case, you should take into account what range of circle dimensions is provided for your tool.

Note!
It is forbidden to use a consumable that is 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 disc will wear unevenly or overheat and get 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 by accurately selecting washers.

Below are the most common internal disc bore sizes.

1. Wheels for dry cutting with a diameter of 115/230 mm, designed for manual angle grinders (grinders) and have an inner hole of 22.2 mm.
2. Analogs in sizes 150/350 mm are suitable for wet cutting with portable stone cutting machines and have an internal diameter of 25.4 and 30 mm.

1. Wheels with dimensions of 300/400 mm are suitable for manual power cutters, they have an internal hole of 25.4 mm. Can be used for dry and wet sawing.
2. Analogues with a size of 500 mm or more are designed for large stationary stone-cutting machines. They have an inner diameter of 60 mm. They are 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 blade of a universal grade. If the material is the same, and it is known in advance, it is more correct to choose a specialized circle.
2. It must be said that different manufacturers used for marking various methods, symbols and indications. Based on this, choosing a circle, you should be extremely careful. Otherwise, the cost of cutting will be unnecessarily high.
3. It is clear that soft materials are processed easily, and hard analogues are difficult. Therefore, for lightweight concrete with a soft filler (expanded clay, slag) or a cellular counterpart, you should choose discs that have hard ligaments. For materials on hard fillers (gravel, crushed granite), circles with soft bonds are suitable.

Which wheel to buy: for dry or wet cutting

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

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

Before buying a disc, find out the following:

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

Tell the sales assistant all these data, and he will select you best option products.

If the wheel has already been purchased, make sure that it is designed for the type of concrete being cut.

1. Putting the circle in the tool, determine whether the direction of its rotation, shown on the body by an arrow, coincides with the direction of rotational movements of the shaft.
2. The unit revolutions must be similar to their indicated value on the disk. On the label, manufacturers write the maximum permitted rotation speed (rpm) and the maximum permissible linear speed (meters per second).
3. Working at the wrong speed can damage or wear the wheel unevenly. Yes, and cutting will be ineffective.
4. Do not tilt the disc to the sides and do not use muscle force (the mass of the instrument is sufficient).
5. If the depth of cut is large, make a preliminary cut (1/5 of the total cut). So you stop the overload of the unit, and it will be easier to get an even cut.
   
6. When processing hand tool concrete slabs with a thickness of 2/4 cm, set the stopper on the disc to the greatest cutting depth. So contact with the material will be minimal. The same preparation is needed if diamond drilling is performed in concrete.

Conclusion

Choosing the right cutting disc for stony material will ensure high efficiency work. In this case, it is necessary to take into account the brand of the circle and the features of the characteristics of concrete. The video in this article contains a lot of additional information.

Quality tile works tool dependent. The times of a minimalist approach to tooling are gone, today it is often impossible to perform cladding at a decent level without having the right tools. First of all, this aspect is important when cutting ceramics. The qualifications of a tiler and the outcome of facing events are highly likely to be determined by looking at the tile cutting machine used by the master. Glass cutters, scribers and even mechanical tile cutters do not guarantee a quality cut of many modern materials. Therefore, in your quest for the perfect pruning, look to an electric tool.

Even today most of wall ceramics lends itself to the good old scriber, and floor tiles mainly by the forces of mechanical tile cutters. But what to do on a complex, in terms of materials, object? The glass cutter does not take porcelain stoneware, and the “mechanics” almost always suffer from backlash. A professional tiler in modern realities is a specialist who has in his arsenal electric tile cutter. On the way to professionalism, you need to understand what specialized power tools are. Manufacturers offer:

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

Manual electric tile cutters

The simplest type of cutting tool powered by mains or batteries. The principle of operation is similar to the angle grinder, the differences are in the "tiled" specialization. Yes, it contains:

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

It is possible to work without dust in horizontal position, so trim the stacked wall tiles won't work clean. There are also larger versions that run on batteries. They already look a little like a grinder, but they still do not reach the title of a machine tool. Their feature is 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 angle of inclination up to 45 degrees. The approximate cost is 23,000 rubles.

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

Stationary machines with a lower motor

This and the next type of tool combines the quality of the cut and the absence of dust - water-cooled machines, which in parallel does not allow dirt to be sprayed. In all cases, the cutting material is a diamond disk. Here it is stationary, one part is above the platform on which the plates are placed, the other is lower, in a tank of water.

The "bottom" orientation of the engine allows you to make machines compact. This circumstance led to the wide distribution of this type. When making repairs in a residential apartment, it is often difficult to find a place for a bulky tool, and it is much more convenient to transport a “bottom-driven” tile cutter. But the main advantage of this type is the ability to cut overall tiles. There are no limiters on the support platform, which expands the format frames. The tiler is limited by skill and physical ability.

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

Some models allow cutting at an angle of 45 degrees. In any case, the engine is stationary, the platform tilts. Disks in machines of this type are used large (180-300 mm). However, the “tip of the iceberg” protrudes above the bed. The rest is given to the hydro-cooling system. This circumstance entails limiting the depth of cut, usually the range is not impressive.

We summarize the advantages and disadvantages of the described type of tile cutters:

• compactness;
• enlarged plate format;

• narrow range of cutting depth;
• insufficient quality of trimming due to manual guiding of the slabs;

To guarantee a high-precision cut and comfortable work, arm yourself heavier.

Stationary overhead machines

Electric tile cutter of this type - professional tool. It is non-compact, relatively expensive and structurally complex. There are two types of "top-drive" water-cooled machines:

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

Which type to prefer, let's leave it to you to decide, there are as many opinions here as there are people. The console electric tile cutter resembles in some ways the machine from the previous section, the advantages and disadvantages of which you already know. Among tilers, the first type of tool is more common. Both types are characterized by:

• the presence of a pump;
• the ability to cut at an angle of 45 degrees;
• cutting height adjustment;
• the presence of clamps, guides and tires;

Pay special attention to all the details of the design, the quality of the final work depends on them. More 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 cut 920 mm, depth - 48 mm. The cost of such a device is 17-18 thousand rubles.

The manufacturer of the tile cutter Corvette 468 is Russia (ENKOR). The line includes machines with bottom location motor, and with the top. The maximum length and depth of cut is for the Corvette 468 tile cutter and is 920 and 60 mm, respectively. There are models with a laser pointer that facilitates precise trimming. Russian machines are united by a strong body, a stable design of moving parts and efficient electronic and hydraulic systems. approximate price this model - 28,000 rubles.

Characteristics associated with the operation of power units

Rotational speed

High spindle speed does not play a significant role here. In order for the cut to be effective in terms of quality and quantity, a diamond blade needs 2-3 thousand revolutions per minute at idle.

Engine power

This parameter is more important, and the more, the larger the plate. tile 750-1500 W is enough, 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, a 350 mm circle is needed. The size of the machine also depends on the power, if you do not plan to work with stone, do not buy a unit with a weight of under a hundred kilograms.

cutting height

This is one of the most important factors. Electric tile cutter and purchased based on the estimated thickness facing material. The mentioned 350 mm is enough to cut boards 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 plates, deterioration in the quality of the cut (chips, etc.) and jamming of the disc.

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

Electronics

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

Mechanical characteristics
