Starrett Ulti-Mate Arbor

Starrett's Ulti-Mate rapid release arbor system allows holesaws to be quickly interchanged without removing the arbor from the power tool. Fit the correctly sized adapter to your holesaws, then push onto the arbor and turn the collar to lock. Removal only involves lining up an indicator on the collar the the holesaw is released! This saves time in swapping over holesaws and reduces the number of arbors needed.
