How to Cut Tiles With a Grinder
To cut tiles with a grinder, you will need an angle grinder, clamps, a dust mask, hearing protection, safety glasses, and a diamond blade for the grinder.
Start by choosing the right diamond blade with a continuous rim for a smoother cut.
Make sure to work in a well-ventilated area and wear protective gear due to the dust and noise.
For straight cuts, use a wet saw, but for curves and holes, use the grinder with a diamond blade.
To cut a circle, tilt the grinder at 30 degrees, cut 1/16 inch deep along the circle guideline, move 1/8 inch inside the line and make a deeper cut, repeat until completely through, then smooth the edges.
For rectangular cutouts, mark both sides of the tile, score the front and cut from the back.
For semicircular cuts, mark the cut, score the face, remove excess with straight cuts, then make spoke-like cuts.
Remember to plan your cuts, use light pressure, and adjust as needed.

Instructions For Cutting Perfect Circles And Squares In Tough Tiles
Cutting perfect circles and squares in tough tiles may seem like a daunting task, but with the right technique, it can be achieved.
To cut a circle, start by tilting the grinder at about 30 degrees and making a shallow cut along the circle guideline. Then, move the blade slightly to the inside of the line and make a deeper cut. Repeat this process, gradually increasing the depth of the cut, until the circle is completely cut through. Finally, grind off any rough edges and trim back to the line for a perfect curve.
When cutting larger round holes for floor drains or shower valves, it’s important to avoid placing the edge of the circular cutout less than 1/2 inch from the edge of a tile to prevent breaking. If necessary, shift the entire layout to accommodate the cutout.
Techniques For Cutting Semicircles And Rectangular Cutouts With A Grinder
Cutting semicircles with a grinder requires a two-step approach.
-
Start by making a dish-shaped cutout for small holes, plunging the diamond blade from the back of the tile. Stop when the slot through the face of the tile aligns with the edges of the desired cutout.
-
Repeat this process with a larger circle for the remaining cuts.
For rough, round holes:
-
Mark the circular cutout on the back of the tile and plunge the blade centered on the hole.
-
Check the slot made by the blade to see when it reaches the edges of the desired cutout.
-
Then, draw a second, larger circle on the back of the tile and rotate the grinder to make plunge cuts until the hole is finished.
To make rectangular cutouts:
-
Precisely mark the front and back of the tile and score the front about 1/16 inch deep along the line.
-
Flip the tile over and make the cut from the back, stopping and checking often until the cut lines up with the corners of the marked square on the front.
In all cutting techniques, it’s important to take the necessary safety precautions.
- Wear protective gear, work in a well-ventilated area, and follow the manufacturer’s instructions for your specific grinder and diamond blade.
With practice and attention to detail, you can achieve clean and precise cuts on even the toughest tiles.
