    Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
    Short Length—The most rigid bits for drilling the straightest holes.
    Extended Length—Drill through panels and thick workpieces with our longest bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard materials.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
    Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.

    Performance similar to solid carbide but at a lower price point. Like carbide bits, these are stronger than cobalt and high-speed steel and maintain their sharp edges when drilling abrasive material. However, when drilling tough metals like iron and hardened steel, upgrade to carbide for longer life.
    Extended Length—Drill through panels and thick workpieces with our longest bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard materials.

    Shown with Carbide Inserts

    (Sold Separately)

    When you need to drill dozens or even hundreds of holes, use a bit with replaceable carbide inserts. Once the cutting edges wear down, just change the inserts instead of sharpening or throwing the bit away. The holes in the bit channel coolant through the tool for more efficient chip evacuation. Also known as indexable drill bits.
    Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Replacement inserts are sold separately.

    Tough and wear resistant, cobalt steel bits last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without being damaged on hard materials, such as nickel.
    Extended Length—Drill through panels and thick workpieces with our longest bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard materials.

    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.
