With the Carat Brilliant eb diamond core bit, you drill quickly and accurately through reinforced concrete and hard natural stone. Thanks to the laser-welded tt segments, you achieve a fast, smooth start and high drilling efficiency without worrying about segment loss. Featuring a 66 mm diameter and a 420 mm length, it lets you core clean penetrations for plumbing, ventilation ducts, and utility lines through structural walls and floors. The standardized 1/2"G connection mounts easily onto your core drill motor, while continuous wet cooling keeps cutting segments cool and suppresses airborne dust during heavy drilling.
