    Reduced-Shank Drill Bit Sets

    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.

    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.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.
    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.
    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.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

    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.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.
    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.

    Reduced-Shank Hole-Enlarging Drill Bit Sets

    An economical alternative to reamers, these sets include four bit sizes for enlarging existing drilled holes. Bits have four flutes that won’t catch on the inside of the hole like standard two-flute bits can, avoiding damage to the hole and your tool. The shank has a smaller diameter than the cutting tip, so you can ream large holes using tools that have small-capacity chucks. Sets also contain four hole-starting bits.

    Drill Bit Sets for Plastic

    The precision-ground, 60° point penetrates gradually to prevent cracking and chipping. It also reduces heat that can deform the material. Use these bits for drilling into acrylic, laminate, and other plastics.
