Precision knurled liner bushing for mounting air-feed drills in fiberglass or plastic tooling. One-piece design has two angled locking surfaces to lock the drill motor in place, for superior strength. Optional heavy-duty type has precisely machined helical locking surfaces that mate exactly with the air-feed collar, for added impact resistance. Milled flats allow close hole spacing.
