The LENOX® SNAP-BACK® Quick Change Hole Saw Arbors feature tool-free* saw and pilot bit change for productivity. The 2-Step Design releases the saw and pilot bit without requiring additional tools. The collar snaps into each position, to allow for single-handed operation, and is reinforced to stay engaged while drilling. LENOX SNAP-BACK Quick Change Arbors are universally compatible** with all threaded hole saws and do not require adaptors for use.
