Drill Through Sheet Metal Building

Self drilling or self tapping metal screws increase productivity by reducing the number of steps required to screw together pieces of metal.

Drill through sheet metal building. This allows you to skip pre drilling a hole into thinner gauges of sheet metal. With a small twist bit 1 16 in. A self drilling screw has a chisel tip similar to a drill bit. Hard metals like steel and larger drill bits require even slower speeds.
