    Drill Bits

    Cut holes in a variety of metals, from the softest aluminum to the hardest steel.

    Our basic drill bit material is also the most versatile. These jobbers' bits have the balance of rigidity and length needed for most applications.
    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.
    Morse Taper Shank—Insert directly into the tapered spindle on machines such as drill presses and lathes.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

    Reduced-Shank Drill Bits

    Cut large holes with drill presses and portable drills that have a standard-size chuck. The shank on these bits has a smaller diameter than the cutting tip. Also known as Silver and Deming bits.

    Drill through walls and thick workpieces with our longest high-speed steel 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.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

    Step Drill Bits

    Drill multiple hole sizes using only one bit. These have steps with progressively larger diameters—the deeper they drill, the bigger the hole. Count the steps as you drill to achieve the proper size. These bits also deburr as they cut, so they're good for thin materials like sheet metal and plastic panels.

    Wear and heat resistant, these bits are versatile for use on a range of materials.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits. These are the best choice for hard-to-machine metals like stainless steel.
    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.
    Hex Shank—Use with portable drills and drivers.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.
