    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.

    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 Carbon Fiber, Fiberglass, and Graphite

    Cut clean holes in abrasive material without fraying or delaminating the surface. Made of carbide, these bits resist wear to retain a sharp edge, even after after hundreds of cuts.
    Carbide Jobbers' Length
    Image of Product. Front orientation. Contains Inset. Drill Bits. Drill Bits for Carbon Fiber, Fiberglass, and Graphite, Jobbers' Length.
    The hardest and most wear-resistant drill bits you can buy in a length that's rigid enough for most applications. These bits stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.
    Diamond Coated—With the hardest finish, these bits have the longest life.
    Brad Point—The sharp center point starts the hole and keeps the bit centered as you drill. Two cutting edges make clean holes, often for installing dowel pins and other hardware.

    Carbide Short Length

    Our shortest and most rigid bits are also the hardest and most wear resistant. They stay sharp at high temperatures and faster speeds for the straightest holes in hard and difficult-to-machine materials. Used in manufacturing and CNC drilling, they last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.
