With the Carat EP07142010 diamond core bit, you drill clean and precise holes through reinforced concrete and dense stone. Continuous water cooling extends segment lifespan while efficiently flushing away drilling slurry. The laser-welded segments provide high strength against segment loss and ensure an accurate, stable start without slipping or heavy vibrations. Featuring a 71 mm diameter and a 420 mm working length, this core drill bit allows you to create deep wall penetrations for pipes and conduits without needing immediate extension rods. Its 1/2" g female thread connection mounts securely onto your compatible diamond drilling machine.
