    Core Drill Bits for Masonry and Concrete

    Remove a core of material with these hollow bits to make larger holes than fluted masonry bits. They're often used for installing pipe and conduit through brick and concrete. The carbide tip resists wear and heat to stay sharp.

    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.
    Pilot Drills—Cut a groove before drilling to make starting the hole easier.

    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.

    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.

    Quick-Change Hex Shank

    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.
    Round Shank—Fit in the chuck of drill presses and portable drills.
    Quick-Change Hex Shank—Simplify jobs by switching bits instead of tools. These snap 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.
