Cutting tile cleanly requires the right tool for the material and the cut. Using the wrong tool results in chipped edges, cracked tiles, and a job that looks sloppy at every edge. Here is when to use each one.
Wet Saw
A wet saw is the most versatile and precise tile cutting tool. It uses a water-cooled diamond blade to make straight cuts, angle cuts, notches, and L-cuts. For porcelain, natural stone, and any rectified large-format tile, a wet saw is the right tool.
Use a continuous-rim blade for porcelain and a segmented blade for most stone. Keep the water flowing, support the tile through the cut, and move slowly enough that the blade is cutting rather than forcing.
For mitered corners, most wet saws have a table that adjusts to 45 degrees. Take the cut slowly and support the tile close to the blade.
Snap Cutter (Manual Tile Cutter)
A snap cutter scores the surface of the tile with a carbide wheel and then snaps it along the score line. It works well on ceramic tile and softer porcelain in smaller formats. It is fast for straight cuts on field tile when you are making many repetitive cuts of the same length.
Limitations: no notches, no L-cuts, no angled cuts. It does not work well on large-format porcelain or dense rectified tile. For those, use a wet saw.
Angle Grinder with Diamond Blade
An angle grinder is best for curved cuts, notches around pipes, and cuts that cannot be made on a saw table because of the tile's position in the installation. It is noisier, creates more dust, and produces a rougher edge than a wet saw.
Wear a respirator. Tile dust, especially from porcelain and silica-containing stone, is a respiratory hazard.
Tile Nipper
Tile nippers are used for irregular curved cuts and small nibble cuts around fixtures. They are not a precision tool. Use them for cuts where a slightly rough edge will be hidden by a flange or fixture plate.
Practical Notes
Always cut a tile slightly long and test-fit before committing to the final cut. A 1/16-inch error at an edge can mean a gap that the trim or caulk will not cover cleanly. For cuts that will be visible, a wet saw with a sharp blade and a slow feed rate gives you the cleanest edge.
Support long tiles close to the cut point on both sides. A tile that deflects under its own weight will crack at the cut instead of at the blade line.
