ABSTRACT OF THE DISCLOSURE A quill drive comprising a housing adapted for mounting on machine tools. A quill is sliadably mounted in a longitudinal bore in the housing, and is longitudinally positioned by a ball screw. The ball screw is driven for longitudinal positioning of the quill by a variable speed, reversible motor. The quill rotatably supports a spindle for driving various cutting tools. The spindle is advanced longitudinally by the quill and is rotatably driven by a second motor. The quill drive can be used singally or in a multiple arrangement on transfer machines or other auto- matic equipment. The unique design has fewer parts resulting in a simple reliable, relatively inexpensive device which is compact and easy to use. A relatively simple modification of the gear box converts the quill drive into a drive for tapping threaded holes.
