dry core bits

Diamond Hole Saws

Eliminate unsightly hammer drill blowouts and slow chisel work .... cut up to 9-inches deep and more through brick and cement block. Save valuable time and money with these efficient work tools that eliminate unsightly patch jobs. Bits are designed for fast penetration and are extremely cost effective. Not recommended for use on reinforced and prestressed concrete.

Diamondsharp utilizes State of the Art Laser welding for superior bonding strength able to withstand heat generated from dry drilling. These hole saws may either be used with a non-percussion type drill or a hand-held grinder equipped with 5/8"-11 threads for direct connection. Other drills fitted with a 3/8-inch 3-jaw chuck require our #101 Threaded Adaptor required to mount any of the hole saws listed.
