    Application

    Reduced-Shank High-Speed Steel 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. High-speed steel is good for general purpose drilling in most metals. Also known as Silver and Deming bits.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    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.
    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.
    Gold Oxide—Like black oxide, this finish adds wear resistance and reduces friction for improved chip flow. Because it’s less prone to flaking off, it offers better rust protection when bits aren't in use.

    More wear resistant than high-speed steel, these bits cut large holes with tools that have a standard-size chuck. The shank has a smaller diameter than the cutting tip and fits drill presses and portable drills. 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. Also known as Silver and Deming bits.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    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—Polished to eject chips, these are also known as bright finish bits.

    Our hardest reduced-shank bits, these stay sharp at high temperatures and faster speeds. The shank is smaller than the cutting tip to make large holes with drill presses and portable drills that have a standard-size chuck. They offer the best performance on hard and abrasive materials, such as titanium. Also known as Silver and Deming bits.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.

    Hole-Enlarging Reduced-Shank Drill Bits

    Image of Product. Front orientation. Drill Bits. Hole-Enlarging Reduced-Shank Drill Bits.
    A simple way to enlarge an existing drilled hole, these bits are an economical alternative to reamers. They 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 standard-size chucks.
    Gold Oxide—Like black oxide, this finish adds wear resistance and reduces friction for improved chip flow. Because it’s less prone to flaking off, it offers better rust protection when bits aren't in use.

    Reduced-Shank High-Speed Steel 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. High-speed steel is good for general purpose drilling in most metals. Also known as Silver and Deming bits.

    These 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.

    Cobalt Steel Reduced-Round Shank Drill Bit Sets

    More wear resistant than high-speed steel, these bits cut large holes with tools that have a standard-size chuck. The shank has a smaller diameter than the cutting tip and fits drill presses and portable drills. 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. Also known as Silver and Deming bits.
