    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.

    The RockPecker Diamond Core Bits come in a large variety of sizes for drilling any hole needed.
