    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.
    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.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.
    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.

    Our shortest high-speed steel bits, these are the most rigid for drilling the straightest holes. They're also good for tight spaces where longer bits can't fit. Also known as screw-machine and stub-length bits.
    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.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    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

    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.
    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.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

    Split

    Combine the toughness and wear resistance of cobalt steel with a short length for drilling the straightest holes. These last twice as long as high-speed steel and can run up to 25% faster at higher temperatures without damaging the bit on hard metals like nickel. Also known as screw-machine and stub-length bits, they fit in tight spaces where longer bits can't.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    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.

    The performance of solid carbide but at a lower price point. These jobbers' bits have the balance of rigidity and length needed for most applications. Like carbide bits, they 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.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

    Carbide Jobbers' Length
    Image of Product. Round Shank. Front orientation. Drill Bits. Drill Bits, Jobbers' Length, Spiral Flute, Round Shank.

    Round Shank

    The hardest and most wear-resistant drill bits you can buy in a length that's rigid enough for most applications. These 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.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on materials like hardened steel, iron, and stainless steel.
    Uncoated—Excellent for a range of metals, they perform best when used on steel, aluminum, brass, and bronze.
    Round Shank—The most common shank type fits in a drill press chuck.
    Four-Facet Point—The most accurate point style, it centers the bit without a pilot hole and keeps the bit stable while drilling hard metals.

    Our shortest and most rigid bits are also the hardest and most wear resistant. They stay sharp at high temperatures and faster speeds for the straightest holes in hard and difficult-to-machine materials. Used in manufacturing and CNC drilling, 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.

    Drill through walls and thick workpieces with bits that offer the performance of solid carbide but at a lower price point. Like carbide, they are stronger than cobalt and high-speed steel to maintain their sharp edges when drilling abrasive material. However, when drilling tough metals like cast iron and hardened steel, upgrade to carbide for longer life.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.

    Chip-Clearing Drill Bits

    With flutes that lift chips out of the hole, you don't have to stop drilling to clear these bits manually. The flutes improve coolant flow to dissipate heat and prevent clogs that can damage the bit and ruin the hole.

    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.
    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 deep holes.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    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.

    Smooth-Finish Drill Bits

    With more cutting edges than other drill bits, these cut continuously and consistently for a smoother finish. They also stay centered to produce holes that are straighter and more accurate. However, since there’s less space between the cutting edges, they don’t clear chips as quickly.

    The hardest and most wear-resistant drill bits you can buy in a length that's rigid enough for most applications. These 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.
    Uncoated—Excellent for a range of metals, they perform best when used on steel, aluminum, brass, and bronze.
    Round Shank—The most common shank type fits in a drill press chuck.
    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.

    Straght Flute

    Our shortest and most rigid bits are also the hardest and most wear resistant. They stay sharp at high temperatures and faster speeds for the straightest holes in hard and difficult-to-machine materials. Used in manufacturing and CNC drilling, 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.
    Uncoated—Excellent for a range of metals, they perform best when used on steel, aluminum, brass, and bronze.
    Straight Flute—Withstand heavy pressure without slipping when drilling hardened steel and other tough materials.
    Round Shank—The most common shank type fits in a drill press chuck.
    Four-Facet Point—The most accurate point style, it centers the bit without a pilot hole and keeps the bit stable while drilling hard metals.

    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.
    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.
    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.

    Left-Hand Drill Bit Sets

    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.

These 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.
    Brad Point—The sharp center point starts the hole and keeps the bit centered as you drill. Two cutting edges make clean holes, often for installing dowel pins and other hardware.
