Starrett A2 Arbor 11mm Shank To Suit 32mm - 210mm Hole Saws

The Starrett A2 Arbor with 11mm hex shank is a professional-grade Quick-Hitch arbor designed for use with hole saws ranging from 32mm to 210mm in diameter. Engineered with an innovative quick-change system, this arbor features two locating pins inserted into the hole saw cap that prevent overtightening on the screw thread, enabling instant hole saw changes without tools and without removing the arbor from the chuck. This arbor is particularly suited to tradespeople who frequently switch between different hole saw sizes during electrical installation, plumbing, or construction work. The Quick-Hitch design significantly reduces downtime and improves efficiency on site, eliminating the need for additional tools to change hole saws between cuts. Available with high speed steel (HSS), HSS extended length, or carbide tipped pilot drills, the arbor accommodates a wide range of applications and materials. The 11mm (7/16") hex shank fits standard drill chucks, whilst the 1/2-20 UNF screw thread provides secure attachment to compatible hole saws across the full 32-210mm size range.
