ABSTRACT:
A power drill system is disclosed which is hand held and manually operable. The drill system includes a drill and a positive feed unit for the drill connected thereto. A clamping member is connected at a lower portion thereof to a housing for the drill and feed unit. The clamp member is pneumatically powered to move it against a workpiece and clamp it against the housing at the location of the drill. A four way toggle switch controls the air pressure to the clamp member allowing the operator to control the clamping operation with one hand while the other hand holds the housing in the desired position.
