With the Carat Brilliant eb diamond core drill, you drill cleanly and quickly through concrete, reinforced concrete, and hard masonry without damaging surrounding structures. Its laser-welded diamond segments deliver exceptional bond strength to handle demanding drilling tasks with ease. Designed strictly for wet coring, water cooling prevents overheating and premature segment wear while flushing drilling slurry away efficiently. Featuring a diameter of 81 mm and a usable length of 300 mm, it is well suited for accurate pipe penetrations and sanitary installations. The standard 1/2"G connection ensures a secure fit on compatible wet core drilling machines.
