Abstract
A combination pilot drill and drive assembly for forming holes in sheet metal panels with one or more draw punches is disclosed. The assembly includes separable drill and drive units which can be cooperably engaged with one another when used to drive a pilot drill, and disengaged when the drive unit alone is used to drive a draw punch. The assembly is ordinarily used with a conventional drill motor, which is used to drive the assembly as a pilot drill and also to drive one or more conventional draw punches with the drive unit alone.
