    Standard

    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.

    Morse Taper Shank

    Image of Specification. Split. Front orientation. Contains Border. Split Point. For Metal.

    Split

    The toughness and wear resistance of cobalt steel in a length that's rigid enough for most applications. Cobalt lasts at least twice as long as high-speed steel. It can also run up to 25% faster at higher temperatures without damaging the bit on hard materials such as nickel.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on tough materials like hardened steel and nickel.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.
    Morse Taper Shank—Insert directly into the tapered spindle on machines such as drill presses and lathes.
    Split Point—Starts cutting on contact so you don’t need a pilot hole. The point also keeps the bit centered for straight and accurate holes, even with a portable drill.
