    Core Bit

    Quickly create large holes in sheets of glass and ceramic using a drill press. These bits drill smoothly through fragile materials, reducing the chance of chipping and cracking. They have a diamond coating, the hardest finish for the longest life. Bits require an adapter (sold separately) to supply coolant during drilling.

    Rebar-Cutting Core Drill Bits for Concrete

    Core out large holes in concrete, even if it's reinforced with rebar mesh. No need to switch bits, these have a diamond-coated edge that keeps on cutting and resists wear to stay sharp.
    Threaded-Hub Shank for Rotary Only Drilling

    Bits are designed for wet drilling on a drilling rig. To avoid damage to bits and tools, do not use for dry drilling or with portable drills or grinders.
