Abstract: A portable tool incorporates a motor having a shaft connected through a gear train to drive a gear slidably mounted on a spindle having an external thread and movable axially in a direction normal to the axis of the motor shaft. A feed gear having internal threads is mounted on the spindle and is selectively driven at a first speed to produce positive feed of the spindle and at a second speed to effect rapid advancement of the spindle. Collars are adjustably mounted on the spindle and are effective to provide precise depth control and automatic disengagement of the positive feed and retraction of the spindle.

Abstract: A portable tool incorporates an air motor which drives a tubular drive shaft splined to a spindle movable axially in a direction parallel to the axis of the motor. The spindle has a hollow rearward end portion with internal threads which receive screw members mounted on a tubular feed shaft also driven by the motor through an adjustable detent clutch. An adjustable stop collar surrounds the spindle and provides precise depth control, an air cylinder provides rapid advancement of the spindle, and the clutch provides automatic disengagement of the positive feed as well as limited rotation of the spindle at the forward end of the feed stroke before the spindle retracts. The controls for adjusting the stop collar and for effecting positive feed and rapid advancement and retraction of the spindle are located at the rear of the tool.
