ABSTRACT:
An apparatus for bearing a tool against a workpiece includes: (a) a pneumatically driven motor unit rotating a drive shaft substantially about a longitudinal drive axis; (b) a process shaft coupled with the drive shaft for rotating the tool substantially about a longitudinal process axis; (c) a flywheel coupled with one shaft of the drive shaft and the process shaft; and (d) at least one urging unit coupled with at least one of the motor unit and the process shaft. The urging unit moves the tool with respect to the workpiece. The flywheel and the one shaft impart inertial rotational energy to the tool after the pneumatic motor achieves a predetermined rotational speed.
