The Carat Brilliant EB14142020 diamond core bit delivers fast, clean drilling through reinforced concrete, standard concrete, and hard natural stone. Laser-welded diamond segments ensure strong, break-resistant performance during heavy coring tasks. With a 141 mm diameter and a 420 mm working length, you can easily drill deep penetrations for ventilation ducts, drainage pipes, and commercial utility runs. Designed for wet use, water cooling flushes away slurry and prevents bit overheating. The standardized 5/4" unc connection fits directly onto compatible diamond core drilling rigs, providing stable power transfer and wobble-free operation on every job.
