Ceramic tile consumption in the U.S. grew to 3.11 billion square feet (a 9.9% growth from the previous year) in 2021. These figures show that tiles are a popular choice for home flooring in the country. Most homeowners choose them for their durability, low maintenance, hygienic properties and versatility. If you are considering DIYing a tile installation in your home, you should know how to cut tiles with a grinder. You need to use the right type of blade (a diamond blade specifically) for the job. Also, wear safety glasses and a dust mask since dust can be harmful.

The time it takes to cut tiles with a grinder depends on the size, type of tile, and the skill of the person cutting it. All you need is a little guidance and practice. With these tips, you can cut tiles with a grinder quickly and easily.
When cutting tiles with a grinder, you’ll need an angle grinder, diamond blade, clamps and a marking tool. An angle grinder is a power tool that uses a rotating disc to cut, grind, or polish materials. On the other hand, a diamond blade is a type of blade used to cut tiles.
Diamond blades are very hard and can cut through tile without chipping or damaging it. And clamps help hold the tile in place while you are cutting it. You’ll need a marking tool to mark the cutting line on the tile.
Other materials include a dust mask (to protect your lungs from debris and dust) and safety glasses (to protect your eyes). You also need to find a work surface that can offer a stable surface to cut the tile. Avail water at the site to cool the blade and prevent it from overheating.
Cutting tiles with a tile grinder can be a great way to get accurate and precise cuts. But it’s important to follow safety precautions and use the right tools. Stick to the following steps to cut tiles with a grinder safely and easily.
Ensure the grinder is in good working order before you start. Check the power cord for any damage and don’t use it if it has any visible signs of damage. If the grinder isn’t in good working order, it could malfunction and cause an accident.
The grinder could make inaccurate cuts if you fail to prepare it properly. So, you should only use it if the blade is sharp. A dull blade won’t cut through the tile cleanly and could cause the tile to chip or crack.
Test the tile cutter on a scrap tile to ensure it’s cutting properly and that the blade is sharp. Watch how it cuts through the scrap tile. Doing this can also help you anticipate the time it will take to cut a single tile.
Clamping the tile to a work surface will help to prevent it from moving while cutting it. If the tile moves while cutting it, it could cause the grinder to slip. The grinder could result in an accident or break down entirely.
If you don’t clamp the tile in place, it could move as you cut it, resulting in an inaccurate cut. The grinder can also create a lot of dust and debris when cutting tiles. Clamping will help to protect the tiles from damage.
When clamping the tile, use a sturdy work surface. Ensure the work surface is stable enough to support the weight of the tile and the grinder without tipping over. Also, the clamp should be tight enough to hold the tile in place but not so tight that they damage the tile.
Mark the cutting line with a pencil or marker will help you to cut the tile accurately. Do this to ensure that the cut is accurate. If you don’t mark the cutting line, it can be difficult to see where you’re cutting, and you could make an inaccurate cut.
You should mark the cutting line to prevent the grinder from slipping. Do this to ensure the grinder passes around the cutting line and reduces damage. A sharp pencil or marker is the most ideal for this task.
Dull pencils or markers won’t make a clear mark and could make it difficult to see where you’re cutting. You don’t need to make the mark too dark, as you will cut through it. A light mark will do the trick.
Use a ruler or straightedge to help you make a straight mark. Then mark the cutting line on both sides of the tile to ensure that the cut is accurate.
Before starting the grinder, put on your safety glasses and dust mask. These safety devices will protect your eyes and lungs from the dust and debris created when using a grinder. You should also plug the grinder into a properly grounded outlet to prevent electrical shock.
Turn on the grinder using the switch on the side. Once the tile cutter is on, adjust the speed setting. Start on a low-speed setting and then increase the speed as needed.
You should slowly cut along the marked line of a tile when using a grinder to keep it in place. If you try to cut it too quickly, the grinder could slip. It could result in an inaccurate cut or the grinder blade chipping or damaging the tile.
Following the marked line perfectly is difficult if you cut too fast. The blade could also overheat and could result in an accident. Fast cuts also make the grinder vibrate and could affect the overall accuracy.
Use a slow-speed setting and apply light pressure when cutting a tile with a grinder. Do this to prevent the grinder from overheating. It also prevents the blade from chipping or damaging the tile.
On a grinder, a slow speed setting is a setting that allows the blade to rotate at a slower speed. You can adjust the speed control knob on the grinder to a slow speed setting for this effect. Observe safety precautions when doing this to prevent accidents or injuries.
Applying less pressure can make it easy to follow the marked line perfectly. The tile cutter won’t vibrate during the entire tile cutting process. Refer to the manual for the various speed settings that the grinder supports.
The blade will get hot while cutting, so it is important to cool it frequently. You can do this by spraying it with water or using a wet sponge. Cool the grinder blade frequently when cutting a tile to prevent the blade from overheating.
If the blade overheats, it could break, resulting in an accident. The blade may also chip or damage the tile under intense heat. Cooling helps prolong its life and make it more efficient.
When the blade is hot, it can create very fine dust that can be harmful to breathe. Cool it to reduce the amount of fine dust produced.
Once you have cut through the tile, remove it from the work surface. Doing this can prevent the blade from accidentally coming into contact with someone or something. If you leave the blade on the work surface, there’s a risk that someone or something could accidentally come into contact with it, which could result in an injury.
Leaving the blade unattended could expose it to elements that can damage it. Broken or damaged blades can’t give accurate cuts. They also have a shorter lifespan.
To keep your grinder blade in good condition, store it safely, clean it after each use, sharpen it regularly, and replace it when necessary. Don’t use the blade for materials that are too hard. You should also follow the manufacturer’s instructions on maintenance and storage.
Always use a diamond blade for the best results. If you’re cutting a curved line, use a diamond blade with a curve on it. Use a tile nipper or tile saw when cutting a small tile.
You may need a wet saw to prevent the tile from cracking when dealing with larger tiles. Check if the tile is chipping or cracking. It’s a sign that you’re applying too much pressure or using a blade that isn’t sharp enough.
Use a lower speed setting once the blade starts to get hot. A dust mask or respirator can help you deal with tile dust if it’s getting in the way of your work.
With proper safety precautions and the right tools, you can know how to cut tiles with a grinder.
Clamp the tile to a work surface to prevent it from moving while cutting it. Mark the cutting line with a pencil or marker before you start cutting, and use a diamond blade for the work to avoid chipping or damaging the tile.

A diamond blade has diamond grit embedded in the steel rim to grind away hard materials.
Stone, porcelain and glass tiles offer beautiful options for bath and kitchen tiling projects. But cutting these hard materials presents a unique challenge. Straight cuts are easy to make with a diamond wet saw. But cutting curves and holes requires special techniques.
In this article, we’ll show you how to use an inexpensive angle grinder with a diamond blade to cut perfect circles and squares in even the toughest tile. You can buy a 4-in. or 4-1/2-in. grinder for as little as $50 and a dry-cut diamond blade to fit it starting at $20. In general, more expensive blades will last longer. When you’re choosing a diamond blade, look for one with a continuous, rather than segmented rim for the smoothest cut.
Be aware, though, that cutting with a dry-cut diamond blade creates a lot of dust and noise. So make sure you cut in a well-ventilated area (or better yet, outside!) and wear hearing protection, a good-quality two-strap dust mask and safety glasses.
Score the front of the tile along the circle guideline with the diamond blade. Tilt the grinder about 30 degrees and cut about 1/16 in. deep.
Move the blade 1/8 in. to the inside of the line and make a deeper cut. Continue moving the blade away from the line and cutting deeper until you cut completely through.
Grind off rough edges and trim back to the line for a perfect curve.
Many tile jobs require you to cut one or more large round holes for floor drains or shower valves. Photos 1 – 3 show how to cut a hole for a shower valve. We’re showing how to cut a hole that’s entirely within a single tile, one of the most difficult cuts. In the next section we’ll show you an easier method to use for cutting curves in the edge of a tile.
Even with this method, try to avoid a tile layout that places the edge of the circular cutout less than 1/2 in. from the edge of a tile. It’s better to shift the entire layout instead. Otherwise, chances are good that you’ll break the tile at the narrow point while cutting.
The method shown for cutting a circle with a grinder and diamond blade requires you to cut around the circle a number of times, making a deeper cut with each revolution. The key is to maintain the same angle and shave off progressive layers, moving the cut closer to the center of the circle (Photo 2).
Make accurate, near perfect circle cuts for shower valves and plumbing pipes with this technique.
Score the profile with the saw, then cut in from the edge of the tile to remove as much waste as possible.
Make a series of closely spaced cuts up to the scored line. Break off the waste. Then grind the edges smooth.
The process for cutting semicircles from the edge of tiles is similar to the technique shown for full circles. You start by marking the cut and scoring the face of the tile on the line. Then, rather than deepen the scoring cut, simply remove the excess tile with straight cuts (Photo 1).
Before you remove the excess tile (Photo 1), be sure to make short cuts on both sides of the semicircle (1 and 2). Then connect the cuts as shown (3). Rather than make this connecting cut in one pass, make a series of progressively deeper shallow cuts until you’re through the tile.
Now complete the semicircle with a series of radial cuts—like the spokes of a wheel (Photo 2). Finish by cleaning up the rough edges with the diamond blade. Or remove the “tabs” with a tile nipper (a pliers-like biting tool). Then grind the edges smooth.
Take a two step approach to cutting smooth semicircular shapes.
Center the cut on the hole and plunge slowly from the back. Stop when the slot through the face of the tile lines up with the edges of the desired cutout.
Draw another larger circle to guide the depth of the remaining cuts. Make repeated plunge cuts until the circle is complete.
Most plumbing pipe holes are covered by a decorative escutcheon or hidden by a fixture base, so a precise round hole isn’t necessary. Use the technique shown here to make rough, round holes.
Start by marking the circular cutout on the back of the tile. Then plunge the diamond blade down through the tile, keeping it centered on the hole so that the slot made by the blade extends equally on both sides of the circle marks (Photo 1). Check often to see when the slot through the front of the tile reaches the edges of the desired cutout. Then use the length of that plunge cut to gauge the diameter of a second, larger circle. Draw that larger circle on the back of the tile (Photo 2). Use this circle as a guide for making the rest of the plunge cuts. Rotate the grinder about a blade’s width and make another plunge cut, stopping at the outer circle. Continue this process until you finish the hole.
Cut small holes from the backside with plunge cuts.
Mark the cutout on the front and back of the tile precisely. Then score the front of the tile about 1/16 in. deep along the line.
Flip the tile over and plunge the cut from the back. Stop and check often. Stop when the cut lines up with the corners of the marked square on the front. Plunge-cut the remaining three sides.
Cutting rectangular or square holes for electrical outlets is simple with this method. The key is to avoid cutting beyond the corners of the square where the cut might be visible. Plunge-cut slowly from the back and check often to avoid going too far.
Make rectangular cutouts with plunge cuts from the back side.
