MB Core Drills

Large diameter metal bond (MB) diamond core drills, ideal for wet cutting corners of hob cut-outs and electrical pop-up sockets on CNC and semi-automatic machines in granite, hard marbles and quartz/engineered stone up to 40mm thick.

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 60, 70, 80, 90, 100, 110 and 120mm diameter, with 7mm high segment and ½” BSP fitting.
