What wheel to saw tiles with an angle grinder. Little tricks

How to cut tiles with an angle grinder without chipping

Often, when tiling the premises with ceramic or glazed tiles it is necessary to trim the material in a certain way. For sawing there is a special tool. a tile cutter. But to buy it to perform a small amount of work is not reasonable. In this case, you can use an angle grinder, although it will take longer to saw. Before starting the process, you need to know how to cut ceramic tiles with an angle grinder, because such cutting has some specific features.

If the main purpose of the tile cutter is to perform a straight cut, then the angle grinder can make cuts of different shapes. Another advantage of using an angle grinder is the ability to cut material of any thickness and hardness. You can trim with it when it is already glued, it is not possible to do it with other tools. No repair can do without an angle grinder, there is no need to have an additional tool to prepare facing or floor tiles.

The angle grinder is good for cutting tiles of different thicknesses

It is best to cut with a small angle grinder, which can adjust the speed. The small weight will allow you to perform more accurate operations. When cutting does not need a lot of power, enough up to 1 kW. A powerful and heavy model strains the muscles, reduces accuracy and precision.

What disk to cut ceramic tiles with an angle grinder

There are many kinds of angle grinder discs that are suitable for cutting ceramic tiles. However, it is necessary to refuse to buy cheap tools, because their lifetime is short and their application can be dangerous.

Important! The right disc will determine how smooth and splinter-free the cut will be.

Stone discs

The most budget option, but in terms of reliability is inferior to all other types. When using it, the thickness of the cut will be much thicker, and a lot of dust is generated during work.

During use, it is necessary to monitor the condition of the stone wheel. And as soon as it is chipped, it must be replaced.

Steel rims

It is the most reliable and robust type of accessory for angle grinders. Steel discs have a diamond coating on the edge. And their service life depends on how hard they are used.

Using a steel tile disc for an angle grinder, you can perform straight and curved cuts without much difficulty.

Segmented dry cutters

This type of tool is distinguished by a surface divided into identical segments. And the cutting edge is diamond-powdered.

Slots in the disc allow it to cool partially during use. This increases the duration of continuous operation to 1.5 minutes. Afterwards, you should let it cool down by holding it idle for 30 seconds.

Solid dry cutters

It is a solid disc with a diamond-coated edge. Useful for edging tiles. Maximum straightness of material edges after using a solid tile disc for angle grinders.

For cooling, periodic wetting of the tile is recommended, as well as spraying it with a spray gun.

Combination disc models

This kind of tooling is suitable for dry and wet cutting. But in contrast to the segmented, it loses in terms of cooling, and from solid. does not give that quality cut.

Important! The disadvantage of combined types of tooling is that they quickly become clogged with fine dust particles, and only concrete, sand-lime brick can be used for cleaning.

Diamond wheel

For more demanding applications, we recommend this kind of tooling. Its peculiarity lies in a special sputtering, which consists of small particles of technical diamonds, applied over a metal base. This allows the disc to withstand high loads.

How to get rid of dust when cutting tiles

Work with angle grinder is always accompanied by a lot of dust and small debris. When working on porcelain stoneware the waste is stone chips. The smallest shards can enter the eye, hair, or scrape exposed body parts. To protect the master is recommended to use goggles, a cap and tight clothing that hides the skin as much as possible.

A protective cover, often provided with the tool, helps to minimize the negative effects of dust. A construction vacuum cleaner should be connected to the spigot.

Another option is to moisten the tiles, the material will become more pliable, and the cut lines will be smooth. The optimal way to minimize dust buildup is to pump water continuously over the cutting element.

Tools and consumables

Nevertheless, there is a solution. for example, angle grinder with diamond disc for stone and concrete. But do not rush to take up the work, because there are certain specifics both in processing technique and in the choice of appropriate equipment.

Let’s start with understanding what kind of angle grinder is better to use. Variants for 230 mm discs are rejected at once: the tool is too heavy and bulky, it is difficult to control during work. 180 mm angle grinder can be used, but only when cutting porcelain stoneware with a sufficiently thick disc extension.

The optimal variant is the angle grinder with a 125 mm disc, which can be held with one hand while working. If even an effective cutting depth of 40mm does not cover the thickness of porcelain stoneware, that’s alright. Practice shows that if you make a cut more than half the thickness, the material splits off perfectly along the line of the cut, after which you only have to trim the edges a little.

Now for the diamond discs. Do not use segment grinding wheels for dry cutting on porcelain tile. Blades of solid type with stepped notches on the edges are ideal, but you need to make sure that the allowable rotation speed of the diamond wheel meets the parameters of the tool.

In addition to an angle grinder with a diamond wheel, you will need some more tools. First of all a plastic bottle with a pierced cap and a piece of thin silicone tubing inserted. Always apply a small amount of water to cut porcelain tiles. otherwise the coating on the disc will not last long. You will also need a pair of quick-action clamps and a piece of steel bar with a 25 mm shelf, the length of which is 15-20 cm longer than the cutting line.

Curved and fillet cuts

Let’s cover such issues as making curved cuts, chamfering and filletting to bring the tiles to the corners without the use of a joint profile. With beveling it’s quite simple, you need a hard diamond cup with large segments. Put the tile with its back side up, and trim parallel to the edge with an indentation equal to the tile thickness.

After that, using the cup gradually cut the corner, ensuring that the line for the marking trimmer connected to the front edge of one straight edge. Periodically moisten the sanding area with water.

Chamfering the front side is a more laborious job. Here it is necessary to use AGSHK, in common parlance. turtles. Manufacturers do not recommend using them for chamfering, but you can do it with care, but it is important not to apply too much pressure on the tool. Hard cups are not good for that: they have big gaps between the segments, which leads to chips and scratches on the surface. And here is a turtle, with due diligence can remove the bevel, almost indistinguishable from the factory, you should only reduce the grain size in the final processing.

To be able to cut curves, as much of the cut material as possible must first be removed with a normal diamond disc. With convex edges it’s easy enough, to cut concave ones you have to divide the clippings into sectors and then remove in fragments. The edge of the porcelain stoneware is then smoothed using a hard diamond cup.

How to cut ceramic with a grinderOne of the tools used for cutting ceramic tiles, is the Grinder. angle grinder (angle grinder), commonly referred to as an angle grinder.

The price range of the various models of the grinder makes it available not so much professionals, while home masters-hamper, so using the angle grinder is necessary to know not only the capabilities of this power tool, but also the additional rules of treatment with his help to avoid injury.

it is better to use an angle grinder with adjustable speed, a small grinder designed for work with disc diameters of 100-125 mm does not perform many operations. You are equipped with a speed regulator.

Speed of the electric motor

The second important thing that determines the quality of cut of hard materials. is the rotational speed of the disc. The higher the speed, the harder the impact, the easier the edge engages in the ceramic.

A quality cut can also be achieved with an angle grinder

During the rapid passage of the tile does not have time to glow, which also reduces the number of chips, so the angle grinder needs a powerful, but compact, so it was possible to manage it quickly.

Safety technology

In order not to get an injury at work with porcelain tiles and cutting tools the rules of safety prescribed by technology should be observed:

  • Wear protective equipment before starting work. Wear long-sleeved suit, closed shoes, gloves, hat, goggles or face shield and a respirator when dry cutting.
  • The cord length of the angle grinder must be at least two meters.
  • Do not make a cut by placing the tile on the edge and holding the angle grinder in an upright position.
  • Hold the tool firmly in your hands and do not apply too much pressure during work to avoid breaking the tile or ripping the cutting disc.
  • Carefully observe cutter’s RPM, optimum cutting speed is 3000-3500 RPM.
  • Carry out the cut by moving away from you.
  • Do not lower the angle grinder into the water.

Make sure the room is well ventilated when dry-cutting.

Gourmets of quality and refinement

It is not a secret that there is a special category of customers that can be called gourmands of quality. They are willing to pay big money to get the job done to perfection. Most likely, it is difficult to convince such a customer that it is possible to cut porcelain stoneware qualitatively enough by hand. The water cut or water-jet cutting of porcelain stoneware can help to solve this problem. This is the modern technology, which allows cutting ceramic tiles with high quality. This operation is not performed at home, as it requires special equipment. The main disadvantage is the high cost of this work, which is unlikely to be affordable to the average customer.

The thickness in waterjet cutting can reach several centimeters, and the product does not need additional grinding. The great advantage of this method is the possibility of high complexity of cut, which is impossible using manual methods. over, the complexity is not only in terms of the pattern of the cut line, but also in terms of the width of the parts to be cut. Waterjet cutting of granite can cut sharp angled pieces to the edge of the tile, cut thin elements, cut holes and other complex cuts. Thanks to this it is possible to create drawings, mosaics, panels and other images from porcelain stoneware of different colors. Since the cut is controlled by a computer, the mating parts can be adjusted to a perfect fit. For real gourmets, they get the result they want.
