How To Properly Cut Porcelain Stoneware Angle Grinder
How and with what to cut porcelain stoneware? At the moment, there are two directions in cutting porcelain stoneware: straight and curved cutting. In connection with this classification, cutting technologies are divided, and, consequently, the means of its implementation.
This tool specializes in rounded holes in porcelain stoneware. The main advantage of the ballerina is that the characteristics of the planned hole can be different, since the parameters of the cutters are adjusted manually. But a ballerina cut usually comes out uneven and curved, so it is not often used when processing tiles, although special nozzles for porcelain stoneware are sold on the market. In addition, the alignment of the device is quite difficult, which can deteriorate both the ballerina and the tiles.
If you need to cut porcelain stoneware into straight mowing lines, then the choice is quite wide, and with curly cuts it is a little more difficult. The scope of use of the hole saw equipped with a carbide tip extends to porcelain stoneware. It is also used for creating rounded holes in hard materials such as cement tiles and stone. The hole saw can cut any quality of porcelain, whether soft or hard, but cutting glazed tiles is slow.
In general, not the most popular tool for processing porcelain stoneware, however with small amounts of work you can limit yourself to them. The tool is easy to use and cuts the tiles exactly where the hand will lead. Its use is justified in cases where it makes no sense to purchase a tile cutter for the sake of processing a small number of tiles.
Like all other tools, the angle grinder is divided into classes, professional and household tools, as well as by their design features.
This is perhaps the most widely used tool outside of the drill. Many people work with an angle grinder, but not everyone is wondering about the correctness of the manipulations performed, from the point of view of personal safety and quality of work. In this article, we want to devote you to the basic subtleties of working with this tool and consider in detail the following questions:
Let’s go in order.
How TO CUT CORRECTLY AN angle grinder?
Before you get started, you need to prepare your angle grinder. We mean the choice of rig (disc). The following points should be considered here:
- Disc diameter. Remember, the smaller the disc diameter, the more revolutions (higher rotational speed) it can handle, and vice versa.
- The choice of a disc depends primarily on the material with which you plan to work and the design features of your instrument.
- Pay close attention to the legend and markings on the disc. Having carefully studied them, you will understand whether the selected equipment is suitable for the proposed work.
Also, always follow safety precautions and wear special equipment such as gloves, goggles, long sleeved robes and closed shoes.
First of all, clear the workplace of unnecessary items. Securely fix the workpiece to be processed, having previously marked it on it, if necessary. Let’s get to work.
Always hold the tool firmly and confidently with both hands. Take a steady body position. You need to stand so that sparks do not fly on clothes and, even more so, in the face during work.
Always remember about such a thing as kickback. This is the most dangerous thing that can happen when working with a grinder. It can occur if the disc is strongly jammed in the workpiece. In such a situation, the angle grinder will be thrown back sharply. Monitor the process to avoid this.
Also remember that the power cord of the angle grinder must be insulated from sparks during operation. If you need to move the instrument to a different work surface, be sure to turn it off first, then unplug the power cord. The same should be done in the event of a power outage. As soon as the power goes out, turn off the instrument and then unplug it from the mains. If this is not done, then when the power is restored, the angle grinder will start to work in a chaotic mode again and can cause irreparable harm to your health, those around you or damage objects around.
The most frequently asked question that arises among novice craftsmen is the following: How to cut an angle grinder correctly: for yourself or away from yourself? Many do not give this special significance, but in vain.
Bulgarian manufacturers advise their consumers the following: The tool should be used in such a way that the course (direction) of the cut coincides with the direction of rotation of the disc.
Experienced craftsmen have a clear answer to this question: You need to make a cut from yourself. This is for your safety. In case the angle grinder is pulled out of your hands, the tool will be thrown in the opposite direction from you. If you cut towards yourself, when the above situation occurs, the tool will fly to your feet. We will not describe the consequences. You can imagine them yourself.
If you are cutting parts or workpieces that have thick metal, cut them in an extremely straight line.
When working on a part such as a corner or when cutting a profile or profile tube, which is usually quite long, cut the overhanging edge. Otherwise, if you make a cut in the place between the supports, such an outcome as a jamming of the blade due to the deflection of the workpiece is possible.
If you are cutting a profiled sheet (sheet metal sheeting), metal siding (metal siding) or metal tiles, take care of the presence of special anti-corrosion substances that need to be lubricated in order to avoid sudden corrosion.
In case you are cutting paving slabs or paving stones, get a special diamond cut disc.
Reinforced concrete, concrete and other similar materials must be processed with special discs for stone.
If you need to cut a gas or oxygen cylinder, be very careful as it may explode due to the remaining trace of gas or condensation. It is better not to carry out such work at home.
If you need to cut glass or, for example, a mirror. The most trivial ceramic disc will suit you.
When working with material such as wave slate, be careful to avoid chipping and unevenness.
It is possible to process rubber with an angle grinder, but not necessary. If you understand what we mean.
Grooves, springs, rebar or channel can also be cut with an angle grinder.
Need to cut drywall or polycarbonate? Do this very carefully to avoid chipping and breaking the material. You will need neatness if you need to cut glass mosaics. For example, if you are cutting off excess parts from a pasted arch, cover the cut and the part to be cut off with masking tape or construction tape. This minimizes the possibility of cracks and prevents debris from scattering on the floor after cutting.
How TO CUT A TILES WITHOUT CHIPS ANGLE GRINDER?
As we said above, the range of applications for the angle grinder is incredibly wide. She also acts as an excellent assistant when cutting material such as tiles or tiles. But, a logical question arises regarding the equipment: How is it better to work on tiles? To carry out this type of work, you need to get a grinding diamond wheel and a tile holder. It is hardly possible to work without dust with this material, so take care of a protective mask in advance.
Let’s take a closer look at the process itself and how to cut tiles or tiles without chips.
- The easiest way is to cut straight. Fix the tile well so that its edge remains suspended along the mowing line of the cut and get to work.
- The next method to be noted is cutting at a 45 angle. This method is more complicated than the first one. First, we cut the ceramic tile with a straight cut. Then, when cutting the disc, the angle grinder is guided at an angle and remove the unnecessary part. Next, we grind the cut with sandpaper.
How TO CUT CORRECTLY THE METAL angle grinder?
First, let’s talk about the dangers that lie in wait for the master when cutting metal with an angle grinder, namely:
- Fragments of the disc, in the event of a break;
- Powerful stream of sparks and small abrasive particles;
- In some cases, the inability to hold the instrument in the hands.
Now, here are some tips for working with metal.
If you have no experience in this type of work, then, for a start, it is worth practicing on unnecessary details. If in the course of work, you decide to change the cutting plane when the disc is inside the workpiece, this will immediately lead to its breakage.
To increase the life of discs, especially expensive ones, they need to be cooled. This is done with water. It is necessary to water the cutting area. It is advisable that you work with a partner who will carry out all these additional manipulations.
Also, breaks of 5-7 minutes every 20-30 minutes of work will help to increase the service life of the equipment, and the tool itself. This rule is especially important when working with household angle grinders. This way you will keep your instrument from overheating.
It should also be remembered that you should not put pressure on the angle grinder during operation, otherwise it may fail due to overheating, or the disc will jam. If you feel that performance is too slow, try changing the drive.
Can the angle grinder CUT WOOD?
Many experienced craftsmen claim that cutting wood with an angle grinder is to be. Our opinion: it is really possible to cut wood with an angle grinder, but it is extremely unsafe, inconvenient, slow and of poor quality. And that’s why.
Firstly, during operation, the disc of an angle grinder gets very hot and becomes incredibly fragile. The slightest misalignment can result in a ruptured disc. You can find out about the consequences of this situation from the pictures on the Internet.
Secondly, when working with a disc equipped with victorious solders, these solders can easily get under the skin. And this is a direct way to the hospital, because you cannot remove them on your own, plus all this is fraught with infection.
Thirdly, when using a disc on wood, the teeth can grab more wood than you expect, and this, in turn, will lead to that. That the angle grinder will simply rip out of your hands. It is very dangerous!
We hope we have explained in an accessible way why you cannot use an angle grinder when working on wood and you will not even try.
But, as practice shows, many craftsmen at home resort to using an angle grinder in the process of processing materials such as chipboard, chipboard, laminate, OSB board or plywood. This should be cut as carefully and in compliance with all safety measures. Otherwise, you can not only spoil the material, but also be injured.
How TO EXACTLY CUT an angle grinder?
In order not to spoil the workpiece and make a high-quality smooth cut of the angle grinder, you will need to perform a number of preparatory measures, which we will discuss in this part of the article.
- Markup. All ingenious is simple. First we mark, then we cut. Take pipe cutting as an example. First, use a chalk or marker to apply the size, then use paper or duct tape. The main thing is that the edge is even. We take the selected auxiliary material and carefully wrap it around the pipe. Its border will be a clear and accurate marking of the cut. When performing work, it is important to remember that under no circumstances should you change the position of the tool stroke. Otherwise, the disc may jam or break. So, do not put additional pressure on the tool, as this will immediately be reflected in the curvature of the cut and spoil your workpiece.
- It is very important to choose the right thickness of the circle. There is a simple axiom at work: the thicker the material you work with, the thicker the disc should be. When choosing a tool, consult an expert in the field and pay attention to the marking of the grinding wheel applied to his shirt.
How TO SAFELY CUT AN Angle Grinder?
The work of an angle grinder is a matter that requires constant attention and control, because the consequences of accidents are irreversible. Therefore, before starting work, take care of the following:
- Take care of the protection of all parts of the body: face, hands, eyes.
- Clean the work area from excess, especially the place where the sparks fly out, remove all combustible materials away.
- The workpiece to be machined must always be securely fixed.
- Be sure to install the protective cover.
- Hold the tool firmly while working.
- At the end of the work, wait until the disc rotation has stopped completely, place the angle grinder with the disc facing up so as not to damage it, unplug the tool from the mains and check that there is no smoke or signs of fire.
What CANNOT BE CUT with an angle grinder? Basic ERRORS
The list below shows the materials that the angle grinder can work with. It is prohibited to work with materials that are not on the list.
- The angle grinder is perfect for cutting materials such as cast iron, metal, steel, copper, aluminum, iron, titanium. You can cut stainless steel or galvanized.
- With the appropriate attachments, you can also work with plastic, ceramics, glass, plexiglass and porcelain.
- Stone, granite, marble, asphalt, concrete or a wall made of it, brick, porcelain stoneware can also be processed by an angle grinder.
An angle grinder comes in handy when you need to cut off water pipes or old heating.
One of the main factors that guarantee the quality of work is the right tooling. If you have any questions or want to purchase discs, please contact our managers at the specified phones. They will recommend suitable discs and advise you on all issues of interest.
Cutting porcelain stoneware by hand
If you decide to put porcelain stoneware in a small hallway, it is impractical to purchase a professional tool. The strength of this material depends on the specific manufacturer, some varieties lend themselves to hand tools.
The simplest, most versatile and inexpensive tool used to cut ceramic tiles is a hand-held glass cutter. It can be roller or diamond. The latter cuts more accurately and better, but wears out faster.
To work, you need a ruler or flat rail. Lay it along the cutter line and press firmly against the tile. The ruler will prevent the cutter from sliding to the side. During the cut, the tool must be pressed against the surface as hard as possible in order to scratch the top layer of the tile deeper. Try to do this in one go, otherwise porcelain stoneware may crack unevenly.
Now the tiles need to be broken. To do this, place it on the edge of the table so that the break line protrudes slightly beyond its plane. Press firmly and firmly on the edge of the tile. If the furrow was deep enough, the porcelain stoneware should break along the intended mowing line.
Another option is to use a manual tile cutter. This tool resembles a glass cutter in principle. It also uses a roller or diamond to scratch the top surface of the tile. But the tile cutter is more convenient and efficient. Its working plane is covered with a material that prevents the tiles from sliding, and a lever moving along the guides helps to create a sufficiently large force.
Cutting porcelain stoneware with a tile cutter is easy. Draw a line of cut with a marker and lay the tile on the work surface so that the cutter wheel runs exactly along the line. Pressing down on the handle of the tool, make a cut and break the tile using a special stop on the working part of the tool.

How To Correctly Cut A Highly Raised Angle Grinder
Most beginners and DIYers prefer to cut porcelain stoneware with a tool with a very large angle of inclination relative to the plane of the tile. The angle can be 45-60 degrees.
The tool can only be lifted high if there is a supporting surface on the cover
In this case, the angle grinder must be held with both hands and at the same time perform small oscillatory movements with the cutting disc. It is as if the porcelain stoneware had to be cut with a hand saw. This is not very convenient, but the method really improves the quality of the cut and prevents the formation of chips.
On the one hand, with such a movement, the angle grinder is easier to control the cutting line, on the other hand, the tool is in an unstable position relative to the markings, which negatively affects the quality of the straightness of the seam.
Cutting porcelain stoneware with an angle grinder: how to saw off without chips
Everyone who has had a chance to cut faience, ceramics, porcelain stoneware with a cutting disc knows perfectly well that the problem is not how to cut. Such an operation is not particularly difficult. The problem is learning how to cut a porcelain stoneware angle grinder without chipping. At the same time, control the process at any stage, otherwise the expensive material will go to scrap.
It is best to cut porcelain stoneware using a guide bar as a support for the angle grinder case
What disc to cut porcelain stoneware angle grinder
Sawing of porcelain stoneware tiles can be performed in two ways, it all depends on the thickness of the material and on how complex the seam is to be cut. Since porcelain stoneware is still not granite, but just an artificial imitation of it, two types of discs can be used for cutting:
- Vulcanite discs based on synthetic superhard ceramics. With such a circle, you can cut thin grooves, corners, trim the edges. In order to cut the expanded clay, an angle grinder over a length of more than 10 cm, they are not suitable, but they are quite suitable for small jobs;
- Diamond cutting wheels. With this tool, you can cut seams of unlimited length. The only drawback of a diamond is the rapid grinding of the cutting edge, which will need to be repaired and cleaned periodically.
The optimum wheel diameter for an angle grinder is 115 mm, in which case the tool is easier to control by holding the body with both hands. A larger diameter blade will require a more powerful tool, such as a circular saw.
Diamond cutting wheels in themselves are quite an expensive and capricious tool, therefore they try to do most of the work with vulcanite discs, only the most delicate operations, such as trimming and adjusting the plane, are performed with diamond powder.
In addition, the angle grinder should have a solid edge without a notch or turtle profile for cutting porcelain stoneware. Such a tool cuts well natural granite, rubble stone, but at the slightest attempt to saw the ceramic granite tiles along the cutting line, a huge number of enamel chips appear on the front surface.
If there is no specific preference for a well-known brand of cutting disc manufacturer, then it is best to buy discs from leading hand tool manufacturers. Simply put. You bought an angle grinder made by Makita, buy cutting discs with attachments manufactured by the same company.
