    Short flutes make shallow cuts through sheet metal and thin-wall tubing without snagging and deforming the material. High-speed steel bits are good for general purpose drilling in most metals.
    Short Length—The most rigid bits for drilling the straightest holes.
    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.

    Spot-Weld-Removal High-Speed Steel Drill Bits

    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.
