    Expanded-Shank Drill Bits

    The shank fits the same-size collet as standard drill bits, so you can spend less time setting up. Because these bits make very small holes, they’re often used for drilling circuit boards.

    Spiral Flute

    Standard

    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.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.
    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.

    Expanded-Shank Drill Bit Sets

    All of the bits in these sets have the same shank diameter, so you can quickly change sizes without swapping out the collet on your tool. Because of their small size, they are often used for drilling holes in circuit boards.
    Carbide Jobbers' Length
    Image of Product. Front orientation. Drill Bits. Expanded-Shank Drill Bit Sets, Jobbers' Length, Spiral Flute.

    Spiral Flute

    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.
    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.
