With the Carat Brilliant eb diamond core bit, you drill smoothly and accurately through reinforced concrete, standard concrete, and hard natural stone. Its laser-welded diamond segments ensure strong bonding and prevent segment breakage during heavy drilling tasks. Continuous water cooling prevents overheating and premature wear, delivering clean, vibration-free 46 mm penetrations. With a usable drilling length of 420 mm, you easily tackle deep core drilling in thick slabs and solid concrete structures. The standard 1/2"G connection mounts securely onto compatible diamond drilling machines.
