    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.
    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.

    Round Shank

    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.

    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.
    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, titanium, and fiberglass.
    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.

    Our shortest and most rigid bits, these offer the performance of solid carbide at a lower price point. Like carbide bits, 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.

    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.
    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 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.

    Drill Bits for Hardened Steel

    Straight flutes withstand the heavy pressure needed to penetrate hardened steel. These bits cut more aggressively and resist stress better than spiral-flute bits.

    Straght Flute

    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 extremely stronger and maintain their sharp edges when drilling abrasive material. But for the longest life, there is no beating carbide.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    Notched Point—The chisel-like point keeps the bit centered and clears chips.

    Drill Bits for Carbon Fiber, Fiberglass, and Graphite

    Cut clean holes in abrasive material without fraying or delaminating the surface. Made of carbide, these bits resist wear to retain a sharp edge, even after after hundreds of cuts.

    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.
