Starrett A10 Arbor 9mm Shank for 32mm - 210mm Hole Saws

The Starrett A10 Arbor is a professional-grade Quick-Hitch arbor designed for use with hole saws ranging from 32mm to 210mm diameter. Featuring a 9mm shank compatible with 3/8-inch chucks, this arbor is engineered for electricians, plumbers, and contractors who require efficient hole cutting in demanding applications. The innovative Quick-Hitch design incorporates two locating pins inserted into the hole saw cap, preventing overtightening on the screw thread. This engineering solution enables instant hole saw changes without tools and without removing the arbor from the drill chuck, significantly reducing downtime on site. The arbor comes equipped with a high speed steel (HSS) pilot drill and features an 8.75mm hexagonal shank for secure grip during operation. The 1/2-20 UNF screw thread ensures compatibility with a wide range of Starrett hole saws, making it ideal for repetitive cutting tasks where multiple hole sizes are required. The 79mm drill length provides adequate reach for standard cutting depths whilst maintaining drilling precision.
