    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.

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

    Hex Shank for Rotary Only Drilling

    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.

    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.

    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.
    Threaded-Hub Shank for Rotary Only Drilling
    Image of Product. Front orientation. Drill Bits. Rebar Cutting Core Drill Bits for Concrete, Threaded-Hub Shank for Rotary Only Drilling.
    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.
    Standard Point—The most common point type handles most jobs.
    Drill Rig Thread Adapters—Use your bit on a drilling rig with a different thread size.

    Drill Bits for Wire Installation

    Feed electrical wire, data cables, and phone lines through walls with the same tool used to make the hole. Once you've drilled, insert wire through the bit's hollow shaft to the other side of the wall. These are simpler to use than flexible-shaft bits since you do not need to strip the end of the wire. Also known as bell hanger bits.
    Round Shank—Fit in the chuck of drill presses and portable drills.
    Black-Oxide High-Speed Steel—Wear and heat resistant, these bits are versatile for use on a range of materials.
    Black-Oxide Carbide-Tipped Steel—Hard enough to drill through masonry and concrete as well as wood.
