Clean cuts
Been in the trade a long time, and gone thru my fair share of core bits—this diamond core bit really impressed me. Ran it thru reinforced concrete on a recent job and it handled the rebar without slowing me down. Clean cuts, minimal vibration, and it didn’t burn up like some others I use. Will be buying more.

Fast on old hard concrete
We have used all sizes but our company mainly uses 4” diamond core bits. With these we were able to achieve approximately 90-110 holes on old heavy concrete! Very very good core bits and always fast shipment.
