The DiStar Rocket is a high-speed dry-drilling core bit built to outlast and outpace ordinary bits on dense, modern tile. Sintered diamond segments laser-welded to the body bite into hard porcelain fast, start clean, stay centered, and resist overheating — so every hole comes out predictable and chip-free.

Built for dry drilling — no water needed — at speeds up to 3,000 RPM on any angle grinder with an M14 or 5/8" shank.

DiStar Rocket Diamond Core Bit — Fast, Clean Holes Without Water

Modern porcelain is dense and hard, and standard dry bits give up fast — often after about 50 holes. The Rocket is built to keep going: its laser-welded sintered segments stay aggressive and stable, delivering 300+ clean holes in 10 mm porcelain stoneware and powering through porcelain up to 20 mm and granite up to 50 mm thick.

It's made for the jobsite, where water isn't always convenient. The bit starts clean and stays centered for smooth entry, so you get accurate, chip-free holes for anchors, plumbing penetrations, cabinet hardware, and accessories — cut after cut, at up to 3,000 RPM. For a cleaner, safer setup, pair it with a drilling dust shroud and your shop vac.

Why Tile Pros Choose It

  • Drills 6x longer: 300+ holes in porcelain where standard bits manage ~50.
  • Fast penetration: Aggressive sintered diamond matrix bites in instantly.
  • Clean, centered holes: Starts clean and stays centered for smooth entry.
  • Dry and convenient: No water needed — ideal for quick on-site drilling.
  • Handles thick, hard material: Porcelain to 20 mm, granite to 50 mm.
  • Fits what you own: M14 or 5/8" shank on any standard angle grinder.

Usage tip: Let the RPM do the work with light, steady pressure — start at a slight angle to set the ring, then bring it upright. Pair with a dust shroud for dry drilling.
