    Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Short Length—The most rigid bits for drilling the straightest holes.
    Maintenance Length—Shorter than jobbers' length, these bits are more rigid for less wobble when drilling hard material. Also known as mechanics’ bits.
    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.
    Black/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.
    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.
    Titanium Aluminum Nitride (TiAlN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron and titanium.
    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.

    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.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Short Length—The most rigid bits for drilling the straightest holes.
    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.

    The hardest and most wear-resistant drill bits you can buy. Carbide bits stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Short Length—The most rigid bits for drilling the straightest holes.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on materials like hardened steel, iron, and stainless steel.
    Titanium Aluminum Nitride (TiAlN) Coated—No drill bits last longer. These are the best for high-speed, high-temperature drilling of very hard and abrasive materials, including titanium and fiberglass.
    Uncoated—Excellent for a range of materials but won't last as long as coated 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.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    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.

    Round Shank

    Three drill points cut just deep enough to separate welded metal panels without drilling all the way through them. Unlike chiseling or grinding through spot welds, these bits won't damage the surrounding material. High-speed steel is the versatile choice for drilling most metals.
    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.

    The flutes spiral in the opposite direction of other bits and stay sharp longer than high-speed steel. They’re primarily used to remove stripped screws. Choose a bit that’s slightly smaller than the diameter of the screw’s head. Set your power tool to rotate in reverse. Slowly drill in the center of the screw head, maintaining constant pressure. As the bit penetrates, it will catch onto the screw and reverse it out of the hole. If the screw is badly stripped, you might need to punch a starter hole. Also known as reverse-flute bits.
    Maintenance Length—Shorter than jobbers' length, these bits are more rigid for less wobble when drilling hard material. Also known as mechanics’ bits.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.

    With flutes that lift chips out of the hole, you don't have to stop drilling to clear these bits manually. They improve coolant flow to dissipate heat and prevent clogs that can damage the bit and ruin the hole. High-speed steel is good for general purpose drilling in most metals.
    High Helix Flute—Less aggressive than parabolic flutes for cleaner cuts in soft metals.
    Parabolic Flute—A U-shaped groove on the flutes cuts faster and clears chips more quickly than high-helix bits, so these are better for drilling deeper holes.
    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.
    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.

    The hardest and most wear-resistant bits for sheet metal and thin-wall tubing. They have short flutes that make shallow cuts without snagging and deforming the material. Carbide stays sharp at high temperatures and faster speeds than high-speed steel. It can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.
    Short Length—The most rigid bits for drilling the straightest holes.

    These bits combine the toughness and wear resistance of cobalt with short flutes for rigidity. The shallow drilling depth makes them less likely to wobble than other bits of the same length, so they stay centered and drill straighter. 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.

    With flutes that spiral in the opposite direction of other bits, these are primarily used to remove stripped screws. Choose a bit that’s slightly smaller than the diameter of the screw’s head. Set your power tool to rotate in reverse. Slowly drill in the center of the screw head, maintaining constant pressure. As the bit penetrates, it will catch onto the screw and reverse it out of the hole. If the screw is badly stripped, you might need to punch a starter hole. Also known as reverse-flute bits. High-speed steel is the versatile choice for drilling most metals.
