ABSTRACT:
A drilling attachment for use with a machine tool that rotates a workpiece in which the drilling apparatus is moved into an operative position to the workpiece by means of the machine tool slide and is rotated with the workpiece so that a drilling member associated with the rotating drilling apparatus is caused to rotate and to enter the workpiece while the same is rotating. The drive means for rotating the drill collet includes an idler gear which allows a greater work area between the rotating portion of said drill attachment and the drill collet on the drill attachment.
