3 Ways to Cut Tile Every DIYer Can Master

Manual snap cutter

The manual snap cutter is the most user-friendly tool, though it is not meant for every tile type. Manual snap cutters work best on ceramic, porcelain tiles up to a 1/2-inch thick, and sometimes glass or mosaic. While it excels at straight cuts and shapes like triangles or rectangles, curves and circles are out of the picture. Using a snap cutter is about finesse, not brute force. “Muscling” it leads to jagged edges and wasted tile.

• Using a square, mark your tile to size. Wear safety glasses—tile fragments can fly when snapping. Pull the lever to the bottom of the rail and place the tile tightly against the fence, aligning your mark with the center mark on the fence.
• Line up the blade at the bottom of your mark. Apply firm pressure—enough to hear a scratching sound and see a visible score line—and score the tile from bottom to top. Two passes are usually enough; do not exceed three, or the tile may chip. Check that you have a continuous score line across the entire tile before proceeding to the next step.
• Place the “foot” of the lever (the padded fork) slightly below the top of the tile. Push down with just enough pressure to break the tile from the top, moving down the tile until it is completely broken. If the tile doesn’t break cleanly, rescore the line with one additional pass and try breaking again.
• Take your cut piece and smooth out the edges with a rubbing stone before installation.

Angle Grinder with Diamond Blade

When you need cuts beyond straight lines, the angle grinder is the tool for the job. While it can cut straight lines, it is ideal for curves and complex shapes such as around plumbing valves or toilet flanges. Always equip it with a diamond blade specifically made for tile to ensure cleaner cuts and minimize chipping. Before starting, always wear safety glasses, hearing protection, and a respirator. Clamp a piece of plywood or other suitable substrate to your workbench to protect it from accidental cuts.

• Mark your cut line and mark an X on the waste side. Clamp your tile onto the substrate.
• Grip the grinder with both hands, one on the main handle of the grinder near the trigger and one on the secondary handle for maximum control.
• Use a spray bottle with water to spritz on the tile and the blade. This helps keep the dust down.
• Turn the angle grinder on, and slowly, steadily make your first pass along your cut line. Move the grinder at a walking pace—too fast causes chipping, too slow can overheat the blade. Turn off the angle grinder and rewet your tile and blade for the second and final pass. Finish your cut.
• Turn off the angle grinder, wait until the blade stops, then set it down and take your cut tile. Smooth with a rubbing stone before installing.

Wet Tile Saw

The wet tile saw is your powerhouse for dense materials like marble, thick porcelain or stone. It uses a water-cooled system to prevent the diamond blade from overheating, enabling smoother cuts and reducing airborne dust. While it may be the best tool for precision cuts, you will get wet. Wearing a garbage bag or a plastic poncho is best to avoid getting soaked. Safety glasses and hearing protection are required; a face shield is optional but highly recommended, as you may get water sprayed back at your face depending on the amount of water in the reservoir. Keep electrical connections dry and away from water spray during operation.

• Mark your cut line with a speed square and note the waste.
• Fill the water reservoir to the fill line marked on the saw. If there’s no marked line, fill until the water is just above the bottom of the blade. This ensures the blade stays wet during cutting, preventing dust and overheating.
• Place your tile on the saw’s table, lining up your cut line with the blade. Bring in the rip fence to align your tile for a straight pass. Lock the fence.
• Turn on the wet tile saw to make sure it works properly. If all works, begin tile cutting.
• With steady, consistent pressure, slide the tile into the blade at a moderate pace (about 1-2 inches per second), allowing the blade to do the work until the cut is complete. Don’t force the tile into the blade—doing so can cause it to kick back, resulting in chipping and potential blade damage.
• Turn off the saw, wait until the blade stops and remove your cut tile. Smooth out the edge with a rubbing stone before installation.

Tip: Always clean and dry the wet tile saw after each use to prevent rusting and clogging. Replace the blade when cuts become slower or rougher

FAQ

How do you cut peel-and-stick tile?

Peel-and-stick tiles are easy to cut with a sharp razor blade and a straight edge, such as a speed square or a ruler. Use a speed square to mark where you will be cutting, and, with a sharp utility knife, score along the edge of the speed square, marking your line with a few passes. Set the tile at the edge of a table and apply a bit of downward force to snap the tile at the scored line.

How to cut a hole in tile?

You can cut a hole in a tile with a diamond hole saw attachment, an angle grinder, or a Dremel tool. When using an angle grinder, cut a hole by cutting in a circular motion or by cutting straight lines inside the hole and breaking it through the center. Touch up inside the hole with a Dremel tool or grind off the broken pieces by going in a circular motion or tile snippers. Make sure to use water when cutting to cool the blade and prevent dust.

How do you cut tile that is already installed?

To cut tile that is already installed, apply painter’s tape where you will be cutting. Mark your cut line on the tape. Using an angle grinder with a continuous or turbo rim diamond blade, score the tile along your marked line with multiple passes until the tile is fully cut. Apply some water to the blade and tile to prevent overheating and dust accumulation. Using a small chisel, remove the tile section and clean the area.
