    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.

    Chip-Clearing Drill Bits for Wood

    Quick-Change Hex Shank

    Prevent clogs that wear the bit and slow down drilling when it gets jammed. The flutes on these bits have an open design that pulls chips out of the hole faster than standard spiral flutes. Also known as pole or ship auger bits, they are used to cut deep holes through lumber, railroad ties, and utility poles.
    Quick-Change Hex Shank—Switch bits instead of tools. These simplify jobs by snapping directly into power screwdrivers, drills, and other tools that accept a 1/4" hex shank.
    Screw Point—Draws the bit into the material without the need to apply a lot of pressure.
    Black-Oxide Steel—The dark finish reduces friction to clear chips more quickly than uncoated bits.
