Almost all ceramic and porcelain tiles can be straight cut very precisely and quickly with a manual tile cutter that scores the surface and then splits it. A wet-saw or handheld grinder can be used to do L-shaped cuts and such. Many glass tiles and mosaics can also be cut with a manual score-and-snap tile cutter. Stone tiles need to be cut with a wet-saw or high speed grinder. Ceramic wall tiles are the easiest to cut and drill into. Today’s dense porcelain tiles require more expensive blades and bits to efficiently cut and drill them. Visible cuts in an installation benefit from being sanded with a wet diamond hand pad to soften and smooth the edge.
