The Starrett SDS Plus Arbor comes with a high speed pilot drill. Allows the arbor to be used in SDS-Plus rotary hammer drills, with the hammer action turned off.

The Starrett A1-1 SDS Plus Arbor made for use with holesaws ranging from 32-210mm. Quick-Hitch arbors feature two locating pins inserted into the holesaw cap to prevent the holesaw overtightening on the screw thread. This allows easy and instant holesaw changes, without tools and without removing the arbor from the chuck.
