    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.
    High-Speed Steel
    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.
