    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.

    Round Shank

    Standard Point

    Not only do these bits bore holes faster than standard smooth-finish bits, they create less friction and heat buildup to last longer. The spurred teeth have a long life, but they're less effective at guiding the bit so cuts on angled and overlapping holes tend to be rougher. Also known as multispur bits.
