Abstract

A pneumatic tool capable of imparting rotary and axial movement to a bit, either singly or together. A single adjustable member selectively provides communication between a pneumatic inlet and only the rotating portion of the tool, between the inlet and the impacting portion of the tool, or between the inlet and both the rotating and impacting portions. Additionally, the adjustable member can be used to provide a blast of pneumatic fluid from the tool.
