    Rebar-Cutting Carbide-Tipped Drill Bits

    No need to move the hole when you encounter rebar in concrete—swap out your masonry bit for one of these cutters. They have a carbide tip that resists wear to stay sharp. Once you're through the rebar, resume drilling with the masonry bit.

    Shank

    The hex shape reduces the chance of the shank slipping in the chuck. Pair these bits with hand-held power drills and hammer drills set to rotary-only mode. Because they use rotary action only, they require more pressure to grind up material than other bits.

    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.
