Starrett Arbors

Hole Saw arbor supplied with extended length 6.35mm (1/4″) pilot drill. Shank size 11mm (7/16″). Screw thread 5/8″-18. Quick-Hitch arbors 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.
