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.
