Tile Drill Bits & Diamond Hole Saws

Drilling tile is not like drilling wood. Porcelain, ceramic, glass and stone are hard and brittle, so the right bit depends on the size of the hole and the surface you are drilling. Each product page lists sizes in millimeters with inch equivalents.

Which tile bit do you need?

  • Anchor and screw holes (3–16mm): a triangle-tip carbide bit for glazed ceramic tile and glass; a vacuum brazed or diamond coated core bit for porcelain, marble and granite.
  • Pipe, faucet and valve holes (20–65mm): a diamond hole saw in your drill, or an M14-thread diamond core bit on an angle grinder.
  • Large openings (60–200mm): electroplated diamond hole saws for drains, recessed lights, vents and sink cutouts.
  • Through tile into the wall behind it: multi-material bits with an eccentric tip drill tile, brick and wood without a bit change.
  • Clean, beveled edges: a diamond chamfer bit deburrs and widens a hole after drilling.

Tips for chip-free holes

Turn off hammer mode, start at low speed and let the diamond grit cut instead of pushing hard. A piece of masking tape over your mark keeps the bit from skating on glazed tile. Keep the bit from overheating: short passes for dry bits, and water only where the product page says it is suitable.
