    Drill Bits for Spot Weld Removal

    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.

    Spiral Flute

    Round Shank

    Wear and heat resistant, these bits are versatile for use on a range of materials.
    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.
    3-Flat Shank—Three flat sides on the shank prevent the bit from slipping in the chuck of a drill press or portable drill.

    The sharp center point keeps these bits from wandering during drilling to cut accurate straight and overlapping holes, even across the grain. Also known as brad-point bits.
    Brad Point—In addition to the center point, these bits have two cutting edges that make clean holes, often for installing dowel pins and other hardware.
    Round Shank—Fit in the chuck of drill presses and portable drills.
    Black-Oxide Steel—The dark finish reduces friction to clear chips more quickly than uncoated bits.
    High-Speed Steel—Wear and heat resistant, these bits are versatile for use on a range of materials.

    Quick-Change Hex Shank

    Center holes perfectly before installing hinges, latches, and other hardware that require a countersunk screw. These bits have a built-in guide with a beveled tip that keeps the bit in position as it enters the material. So instead of measuring and marking, use your hardware as a template to drill the pilot holes. Once screws are installed, they're straight and the heads are flush. Also known as Vix bits.
    Quick-Change Hex Shank—Simplify jobs by switching bits instead of tools. These snap directly into power screwdrivers, drills, and other tools that accept a 1/4" hex shank.
    High-Speed Steel—Wear and heat resistant, these bits are versatile for use on a range of materials.

    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.
    Carbide Jobbers' Length
    Image of Product. Front orientation. Contains Inset. Drill Bits. Drill Bits for Carbon Fiber, Fiberglass, and Graphite, Jobbers' Length.
    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.
    Diamond Coated—With the hardest finish, these bits have the longest life.
    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.
