The tapered shank of the driving shaft fits into the matching bore of the machine tool spindle. A spring loaded locking bolt has a locating key and a stop which engage an indexing device attached to the spindle housing of the machine tool. This angle drill attachment makes it possible to drill holes on five sides of the workpiece.
