Starrett A2 Arbor

Quick-Hitch arbors with high speed steel (HSS), HSS extended length or carbide tipped pilot drills feature two locating pins inserted into the hole saw cap to prevent the hole saw overtightening on the screw thread. This allows easy and instant hole saw changes, without tools and without removing the arbor from the chuck. For use with hole saws ranging from 32-210mm. Permit instant change of hole saws without tools or removing the arbor from the chuck
