    Changeable-Size Core Drill Bits for Masonry and Concrete

    Instead of investing in multiple bits, change the bit body to drill a different-sized hole. These hollow bits remove a large core of material from concrete, brick, and masonry for installing pipe and conduit. The carbide tip resists wear and heat to stay sharp. Bits include a pilot drill to make starting holes easier.

    SDS-Max

    Shank

    The slotted shank is compatible with SDS-Max-drive rotary hammers. These bits use simultaneous rotary and hammering action to penetrate material. Also known as percussion or impact bits.
    Standard Point—The most common point type handles most jobs. However, for more aggressive cutting that generates a lot of heat, consider a multipoint or serrated bit.

    Spline

    Shank

    The shank has 12 splines for use with a spline-drive rotary hammer, which rotate and hammers bits simultaneously to penetrate material. Also known as percussion or impact 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.
