The first shank includes a first threaded portion upon which a first tool bit is receivable. A second shank is coupled for co-rotation with the spindle and extends outwardly from and coaxial with the first shank. The second shank has a second diameter that is smaller than the first diameter and a second threaded portion upon which a second tool bit is receivable.
