    Round Shank

    3-Flat Shank

    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 is the versatile choice for drilling most metals.
    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.
