Fast-Cut Core Drills

Metal bond diamond core drills, perfect for wet cutting clean holes in granite, hard marble and quartz/engineered stone up to 50mm thick in CNC, portable and semi-automatic machines.

The internal and external vacuum brazed diamond strips protect the drill walls and stop the stone slug/pellet from jamming inside the drill.

Available in 12, 16, 20, 22, 25, 28, 30, 35, 40, 45 and 50mm diameter, with 7mm high segment and ½” BSP fitting.
