With the Carat Brilliant eb diamond core bit, you drill clean and accurate holes through reinforced concrete and dense natural stone. The specialized tt segments ensure a fast, smooth start without drifting off mark. Laser-welded segments provide high strength against detachment during demanding coring tasks, while continuous wet drilling keeps temperatures down and effectively suppresses dust. Featuring a 22 mm diameter, a 300 mm working length, and a standard 1/2"G thread connection, this bit mounts easily onto handheld core drill machines to install pipes, conduit, and wiring effortlessly.
