HEAVY-DUTY TAPER-LOK LINER CL-HLL-16521
Precision liner bushing for mounting air-feed drills through a jig plate. 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. Press fit into jig plate, then fasten from behind with a Lock Nut (order separately). Patent no. 3,015,242.
