What to cut and how to avoid chipping on porcelain tiles at home
The need to cut porcelain tiles occurs in situations where tiles need to be trimmed to the right size when laying floors, walls, stairs and various surfaces indoors. Since this material is very hard, it is not easy to work with it. Different tools and appliances are used for this.
Ceramic granite tiles are relatively new on the construction materials market, but they have already gained popularity due to their high performance qualities, which combine the properties of natural stone and ceramic. This tile material is obtained by dry pressing of a homogeneous mixture of quartz sand, illite clay, kaolin, feldspar and mineral colorants. Ceramic granite tiles get their final appearance after firing in special furnaces at high temperature (1200 1300°C).
The material has the following characteristics:
- High hardness. 7-8 units. Mohs scale (corresponds to corundum);
- Wear resistance and durability;
- Hygienic and easy care;
- low water absorption;
- resistance to corrosive environments;
- environmental friendliness;
- frost resistance;
- fire resistance.
Because of the almost complete absence of pores, the extremely high strength and other features of the material is difficult to handle. We recommend the use of specialized tools for cutting porcelain tiles, which allows you to get an even quality cut.
Perfect cutting of porcelain stoneware HOWEVER.
Hello, everyone! This is the situation I have now:
I lay porcelain tile 1200×600 on the floor and on the walls. thickness 8 mm. and 11 mm. respectively. Need to make a perfect 45 degree cut (no chips). Question. as.
Bought yesterday an electric tile cutter (40k paid). Saws with small chips. Today I bought a Boshevsky disk (5,000 K paid). Saws better, but there are small chips.
Any advice?? I’m oooo very slow to make cuts and circles change. Is it realistic to make a perfectly clean cut or as close as possible to such a cut?
There’s like a standard disc goes 300 mm in diameter, without the segment. No vibration/shaking. The water supply is fine. There are small chips, though.
at 2.4 per meter (142 meters in total).square))) The customer kind of agrees and on the corners instead of “under 45”, but here I myself would like to have a splinter-free cut. Why wouldn’t I agree with you?? By the way, many of those who were in front of me. On the fact. The tiles are of very good quality, the EPS is there, the floor is flat.
There, by the way, the customer is looking for a performer to tile the fireplace. If I’m not mistaken, the tiles are 2000x3000x4 One tile costs 60k. We need to cut holes for the furnace and other openings in it (with an even cut).д.
And you can’t get away with stainless profiles? Otherwise, in Heil, they’ll be chipping with pokers in a jiffy. Yeah, and outside corners that sharp are dangerous too. You will bump into it accidentally. Thank you for the offer. While I’m busy. For an indefinite period of time. If I was free, I would take it. 50 т.р. do not roll on the road. Understanding how and what to do, there is. Yesterday, too, I had to give up laying 1.50.75 in the bathroom for the same reason. I don’t know where to look for workers. Only people have learned how to make clay tiles under 45, and here it is already required to make them out of flint. But if you get the hang of it, you don’t need a machine like yours. You can do it this way, too. Just hand sanding. Most of the work here, it takes a lot of patience.
))) в “zeros” I must be mistaken, how big can a fireplace be if you want to tile it with a 2 x 3 meter tile??))). for cave trolls or something.
there’s no such tiles, there’s no point in googling))) laminam. is that? emdaef panel. made of paper, glue and other chemicals well. It’s not ceramic tiles. ))))))))

😀 LaminM and laminT are somehow different things.I first came across her 12 years ago, but the customer could not meet the price :'( Here’s romann, tiled something similar, with a different name and a more democratic price, perhaps we have established production.
For large-format tiles, you need to make special rails with suction cups. (10,000 to 12,000). 4mm thickness is most likely not ceramic, but poured like liquid stone. And most importantly, it’s an assistant without tremor:)))) the cost of the work is almost the cost of the tiles.
on the cost-customer understands everything. On all the necessary hemlines. He is ready to buy everything he needs at his own expense, except for an assistant without a tremor!)))
I had the experience of mounting 2500×1500 with a 45 kerf, it was not worth it. Too much responsibility. I wrote about the helper for a reason. He got nervous and nearly dropped the panel. Should have poured 100-150 grams:)))) Panel helicopter, a perfect fit is almost impossible, then had to fit the entire tile to this misunderstanding.
I am not a builder/finisher, so I will ask. Do they use a crane to lift the tiles and jack them up?? Or maybe you’re trolling us? 🙂
Yes, now producing these tiles, by weight alone count pack of porcelain tiles which may be 60 by 60 Chinese weighs 20-25 kg there are three tiles.Ie the weight of 2 tiles is comparable to the weight of 120 x 60. Another question is why you need such a tile and how easy it is to work with it? I believe that since domestic manufacturers were the first to get excited about large sizes estima and they have their own production svp, probably in order to save svp? 🙂
20 to 60, 30 to 60 I can still understand but 120 to 60 or 120 to 300 to me so overkill and work with such plates is not convenient
In a large disk runout is more by definition, do not believe take the angle grinder with 110-125diskom yes try, the cut will be cleaner but t.к. hands crooked)

there are 5 tubes in the minimum (mains, but I’m a stingy one. I want a battery-operated and adjustable! and it is a spot vaschanha) worth, will be in the family if you buy. the fifth angle grinder (including a large brick capable of cutting a hollow brick in one pass, not counting the three drills). TOAD. 🙂 and Latre (you do realize that THERE IS NO REOSTAT. and the scheme of regulation on the thyristors is only controlled by a variable resistor, in common people called a rheostat) is also tried, as well as at 36 volts with step spetstrans. it solves the problem of boring and grinding (eg, metal to perfection). but the adjustment of at least a household Bosch. much better, it’s a shame. but it’s a pity. here I am looking at the old voltage regulator. I want to build a speed regulator on it quickly. but with a reserve of power for 10 grinders?
I once rented an electric tile cutter with a water pump, it saw without chips, it certainly depends on the tile, but maybe the model also matters, RPM, the amount of water fed to the drive.
Got used to it already. Adjusted the machine, made the cut, filed with turtles of different grit and all came out. Drove that it is necessary to cut only the edge of the disk with a dusting (lower if. There are chips on the left side of the tiles).
Theme can be closed. The tile is laid. It is true, there is more volume there. the same (the mantel is about 8 meters high and the apron is 3m x 5m. Thank you all for the advice!
Small chips are unlikely to be avoided, you need a high speed and disk thickness is thinner, and the drive 300 mm., It’s at least 2.8mm thick. It might be worth trying not to finish sawing a little and break towards the cut and glue the tape to the glaze where it crumbles.
What determines the price of the wheel
Among domestic manufacturers it is necessary to allocate such as:
Obviously foreign manufacturers will cost more than domestic ones because of the markup for the cost of brand and shipping. According to the results of independent testing of well-known manufacturers on the market, it was Zubr showed results that significantly exceed those of foreign models.
Technology of diamond abrasive spraying on a cutting edge also affects the disk price. The most common technologies are:
- Brazing. We mentioned these products above where the abrasive shavings are soldered to the edge with silver solder. The technology is cheap and reduces the cost of models, but when heated, the solder loses its qualities and the diamond sputtering quickly wears out. Consequently, the life of the wheel 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 the diamond sand is firmly soldered into the surface of the wheel. The lifetime of such products is considerably longer than previous ones, the price is still affordable. This method is usually used for combination wheels, which are suitable for dry and wet cutting.
- Laser brazing. This is a very expensive technology and is used for industrial models. Such a circle can cut everything, from white brick and ending with granite.
Important! Today’s market is filled with blatant imitations of well-known brands, so when buying a disc for dry cutting ceramic granite or tiles, pay attention to the price. For example, a wheel from a Bosch or HILTI manufacturer can’t possibly cost 900-1200. Purchase only at specialized retail outlets or branded outlets.
This tool is suitable for straight cutting ceramic tiles, if the volume of tiling is small. In large-scale finishing works use more advanced devices. Tile tongs is an improved roller glass cutter, additionally equipped with a double-sided blade that breaks the cut tile (as in a hand held tile cutter). Otherwise, this device can be called a primitive handheld tile cutter, which lacks a frame. Use pliers to cut off the excess in this sequence:
- We drew on the “face” of the tile approximate line for the trimmer;
- We match the marked segment with a construction ruler;
- along the ruler with an even pressure to conduct a roller, which is equipped with pliers;
- put a tile with a cut glazed layer between the working arms of the tool so that the groove on the tile was between the legs of the tongs, forcefully, but smoothly, close the handles
Tip. To obtain an even edge when breaking the tile with the tongs, place the cut-off groove exactly in the middle of the tongs and perpendicular to the tongs.
How to stay safe while cutting
Safety rules when working with tools for cutting as simple as possible, their observance is obligatory, because your health and even life depends on it. When using non-electric tools, the basic set of protective equipment are gloves and goggles. Gloves will help to avoid cuts from sharp edges of the material and glasses will prevent splinters and dust from getting into the eyes.
When working with an electric tool, angle grinder or tile cutter, special attention must be paid to safety:
- Never change or clean the cutting disk while the machine or angle grinder is plugged in. The equipment must be completely de-energized.
- The cutting wheel must not be inserted into the porcelain tile by more than one-third when cutting with an angle grinder. When working with the tile cutter, the depth of the wheel must not exceed one half.
- The angle grinder must have a safety guard and the tile must be cut in the direction away from yourself.
- Wear protective clothing made of thick material and do not leave exposed body areas. When the cutting wheel is heated, spray particles can bounce off and leave burns on the body.
- It is important to use gloves of thick fabric. Experience has shown that knitted gloves are unsuitable and could cause injury. Often, if the tool is mishandled, the disc or locknut will catch the glove threads and can twist.
- There must not be any loose straps or clasps on clothing, and if you have long hair, you must hide it in a headdress.
Since power tools create noise and often a lot of dust, goggles, headphones and a respirator are mandatory protective equipment.
How to secure an angle grinder?
The quality of the work depends to a large extent on the correct positioning of the tool. Fasten the angle grinder to the leg of the workbench is better to disk upwards. Pay attention that the disc doesn’t reach the surface of the table for a few millimeters. Next, you need to attach a sheet of metal to the table, on which the tiles will be placed.
If you place the tool horizontally, then the disk will be outside the table. And then you have to cut by weight. It is a more complex variant that is not worth choosing only for a person who is just mastering the finer points of handling an angle grinder.
In addition to protection against dust, it is also worth thinking about ensuring that there are no injuries. Besides the obvious danger from the rotating surface, there is the risk of not being able to hold the tool. If the tile suddenly flies out from under the rotating wheel, the tool can inertia drive further, deforming the tile.
To avoid this, it is necessary to hold the tool firmly, in addition, you can use a special workbench, to which the tool is attached, and the tiles themselves will be transferred. This is reasonable if a large amount of work is required.
Subtleties of operation
The first, most important thing for a beginner to use an angle grinder is to understand that you don’t have to cut through the tile. It’s enough to run a deep line for the trimmer, and afterwards you can easily break into several pieces.
Of course, it is worth understanding that it will not do without dust. But you can minimize debris by using a tool guard. You can also use wet cutting tips. If you pre-soak the tiles in cold water, they will be more pliable. This method guarantees smooth lines without sharp cracks. the angle grinder ensures a good quality of cut and no chips.
The next important question is on which side of the tile to make the cuts. If you cut from the front, you will definitely have fewer chips. This can be important when installing outlets, for example. Then the body will definitely fit into the hole.
If you cut from the back side, the appearance of chips on the front part is possible. It is better to choose this option if these tiles are not in view.
Cutting ceramic tiles with an angle grinder
Cutting ceramic tiles at home is performed by means of an angle grinder. If you don’t have a specialized tool for ceramics, an angle grinder is always handy. In addition, there are cases in which you need to make a fine adjustment, cutting off just a thin strip of 0.5-2 cm. A tile cutter in this case will not help because of its widely spaced supporting legs.
How to cut ceramic tiles at home with an angle grinder? It is enough to take a pencil or marker, make a line for the trimmer on the ceramic tile, and then make the cut. During the process, you should monitor the heat. It is not necessary to saw it in one approach. Otherwise the product can crack. For the desired result, the movement of the angle grinder is made smoothly, without pressing.
Tip! Pass the angle grinder on the drawn line should not be in the center, and along the line, from the side of the trim part. By cutting the ceramic along the strictly marked line, the fragment will become a couple of millimeters smaller.
How to properly cut the angle grinder ceramic tile? There are a few tips for this:
- It is better to perform the process on the weight, in this case, the vibration from the tool will be compensated by your hands.
- After trimming, the edges can be sloppy. So at the point of the first cut, a neat re-pass is made.
- To smooth out the irregularities will help sandpaper.
- The angle grinder is a very dangerous tool. To protect yourself, you should wear gloves, wide goggles or a screen before cutting. You need tight clothes and leather shoes.
Types of discs for cutting porcelain tiles and ceramic tiles
Many people go to the store and try to buy a disc for cutting tile or porcelain tile, thinking that these are two different circles. As a matter of fact, a disc should be chosen not only according to the type of material, but also for its capacity, and for the tool that is used for cutting. All available samples can be divided into three basic types, then we will consider each of them in detail.
The circles for wet cutting
In the photo a diamond disk for wet cutting of porcelain tiles is shown, it is also called a solid disk. The same discs can also be used to cut tiles in small quantities. Designed for wet cutting, i.e. with coolant. It can be used with electric tile cutters and thanks to its solid cutting edge it makes a perfectly smooth cut with almost no splinters.
With water cooling, the cutting time is practically unlimited, which is ideal for cutting large tiles of porcelain tile or floor tile, and for working with large volumes.
For your information. These wheels can also be used with an angle grinder, but only for small cuts and only on tile. In this case the cutting wheel should not work longer than 10-15 seconds, after which it must work at idle speed for 20-30 seconds to cool down.
Diamond chips are applied to the cutting surface of the disc with a silver solder, which loses its strength when heated and the sputtering quickly wears out.
Ceramic tile laying technology on the floor
Important. Many people often make the mistake when immediately after cutting tiles with an angle grinder, they lower a solid disc into a tub with water to cool it. Rapid cooling causes microcracks in the sputtering and in 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 people.
Dry cutting discs or dry cutters
A disc for dry cutting of porcelain tiles or tiles is called a segmented disc or a dry cutter. The product does not need water cooling because it is designed with notches from the edge to the center. These cutouts divide the edge of the circle into segments, are used to cool the product during operation and compensate for the expansion of the metal when heated.
Gourmet quality and refinement
It is no secret that there is a special category of customers who can be called quality gourmets. They’re willing to pay a lot of money to get the job done to perfection. Most likely it will be difficult to convince such a client that it is possible to make a rather good cut of porcelain stoneware manually. The water cut or waterjet cutting of porcelain stoneware can help to solve this problem. This is the modern technology, which allows cutting ceramic tiles with the highest quality. At home this operation is not performed, 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 of the waterjet cutting can be up to several centimeters, and the product does not need any additional grinding. A great advantage of this method is the possibility of high complexity of the cut, which is not possible with manual methods. over, the complexity refers not only to the pattern of the cut line, but also to the width of the cut parts. Waterjet cutting of keamogranite allows you to cut parts at an acute angle to the edge of the tile, cut thin elements, cut holes and other complex cuts. This makes it possible to create drawings, mosaics, panels and other images from porcelain stoneware in different colors. Since the cut is controlled by computer, it is possible to fit the mating parts with perfect accuracy. Really, gourmands will get the desired result.
