When you’re drilling tile, the right bit is the difference between a clean pass-through and a cracked tile. This collection focuses on diamond core drill bits (often called tile hole saws) and the jobsite accessories that help you drill straighter, cooler, and with less edge damage—especially on dense porcelain and finish-sensitive surfaces.

What’s in this collection

  • Dry diamond core bits (wax-filled): Great when water isn’t practical. Wax-filled designs help manage heat during dry drilling and are a go-to for quick holes in finished spaces.
  • Wet / wet-dry diamond core bits: Electroplated or vacuum-brazed styles that can run cooler and often last longer—use water when possible for best performance and cleaner edges.
  • Accessories & helpers: Items like cooling wax, drill guides, and other add-ons that reduce walking, improve control, and keep your tooling cutting consistently.

How to choose (pro checklist)

  • Pick the diameter by application: Match the hole size to anchors, valves, pipe sleeves, or mounting hardware—measure twice before you core.
  • Match the bit to your setup: Confirm shank/arbor compatibility (common options include 5/8"-11, M14, and hex) for your drill or grinder adapter.
  • Control the start: For glossy tile, use a suction-cup drill guide (or similar guide) to prevent walking; start at a slight angle, then square up once it bites.
  • Run it like a tile pro: Low RPM, no hammer mode, steady feed, and “pulse + cool” on dense porcelain helps reduce heat and micro-chipping. Keep glass supported and wet for best results.
