Product Information
The BIHUI® Diamond Turbo Drill Bit Set includes six vacuum-brazed diamond core bits and a thread adapter for drilling porcelain, marble, and granite. The kit provides multiple hole sizes for tile and stone installation while supporting operation with compatible angle grinders and electric drills.
Core bit sizes include 1/4", 5/16", 3/4", 1-3/8", 2", and 2-3/4". This range covers small fastener and anchor holes as well as larger openings for pipes, valves, fittings, and other plumbing or electrical penetrations.
Each diamond core bit features a 5/8"-11 threaded connection for direct mounting to a compatible angle grinder. The included 5/8"-11-to-hex adapter allows the same core bits to be mounted in a compatible electric drill, providing greater flexibility across different installation conditions.
Vacuum-brazed diamond rims support fast drilling and extended service life in hard tile and stone. The six core bits and adapter store together in the included aluminum carrying case for protection, organization, and transportation between jobsites.
