Weha RockPecker Diamond Core Bits


Weha RockPecker Diamond Core Bits are wet diamond core bits that have a free cutting bond and design to quickly drill holes in granite, marble, quartz, engineered stone, quartzite, cultured marble, limestone, travertine, and other stones.

These thin wall core bits, with only a 2mm thick diamond rim, will “bite” into the stone quickly and drill fast through the stone.

These wet diamond core bits are made with a special bond that favors the hardness of quartz materials, along with the resin that they are made with, to drill very fast and very clean.
