The Starrett A10E arbor is a professional-grade quick-change attachment designed for use with hole saws ranging from 32mm to 210mm in diameter. Featuring a 9mm shank and Quick-Hitch technology, this arbor enables instant hole saw changes without tools and without removing the arbor from the drill chuck. The arbor incorporates high speed steel (HSS) pilot drills and features two locating pins inserted into the hole saw cap. These pins prevent the hole saw from overtightening on the screw thread, ensuring quick and reliable tool changes on site. With a 1/2-20 UNF screw thread and 8.75mm hex shank, this arbor is compatible with 3/8" chucks, making it suitable for a wide range of professional power tools. Ideal for electricians, plumbers and construction contractors who need to cut multiple holes throughout the day, the Quick-Hitch system significantly reduces downtime between cuts. The 92mm drill length provides adequate depth for most standard applications, whilst the tool-free change system allows tradespeople to switch between different hole saw sizes rapidly without interrupting workflow.
