A tap and drill set includes bits that drill a hole and thread it for a screw in a single motion. They also can deburr sharp edges when drilling into metal. Thanks to the unique shape of the bit, the surface cuts through material, tapping and countersinking as it goes. When choosing a good kit, consider its construction materials. High quality metals like hardened steel can deal with sheets as thick as 10-gauge steel without much issue. A good hex-shaped shank will also keep the bit secure in the drill so you don't have to worry about it coming loose.
