    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.

    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.

    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.
