Cutting and Shaping of Tiles
This domain covers straight cuts, curves, notches and holes - and the edge quality that separates a professional finish from a chipped one.
Methods and when to use them
- Score and snap: one firm pass with the cutter wheel on the glazed face, then snap. Fast and chip-free on standard ceramic.
- Wet saw: controlled, cooled cut for porcelain, large format and stone; feed slowly and let the blade cut.
- Angle grinder: straight cuts, L-cuts and notches; support the tile fully and keep the blade wet or use extraction.
- Nippers: small curves and waste removal around fittings, working from the edge inward.
- Diamond hole saw or core bit: pipes and tap holes; drill from the glazed face at low speed with water, backing the exit with a scrap board.
- Files, rubbing stones and polishing pads: dress cut edges, especially on stone and visible external corners.
Worked example
A 32 mm pipe must pass through a wall tile. Measure the pipe centre from two fixed references, not from the tile edge you are about to cut. Use a 40 mm hole saw - 4 mm clearance all round, filled later with flexible sealant - drilling from the glazed side at low speed with water. Reasoning: a tight hole leaves no room for movement, and a dry high-speed cut chips the glaze. Finish with an escutcheon so the sealant joint is neat and hidden.
Traps that cost marks
- Scoring the back instead of the glazed face on a snap cut.
- Hammer mode on porcelain - instant cracking.
- Dry-cutting indoors without extraction or a respirator.
- Cutting a hole exactly 32 mm, leaving no allowance for sealant or movement.
- Forgetting the perimeter gap when cutting edge tiles.
