With the Carat Brilliant EB07642010 diamond core bit, you drill smoothly and accurately through reinforced concrete, plain concrete, and hard stone. The laser-welded segments ensure high durability and segment retention under heavy use on site. Thanks to the dedicated tt segments, you achieve an immediate bite without slipping across the work surface at startup. Designed strictly for wet drilling with continuous water cooling, it prevents overheating and suppresses dust while creating clean penetrations for plumbing, pipes, or ventilation ducts. Featuring a 76 mm diameter, a 420 mm working length, and a standard 1/2"G thread connection, this core bit mounts securely to your compatible diamond drilling machine.
