Introducing our 'Starrett A1E Arbor with 9mm Shank', explicitly engineered to accommodate 14mm - 30mm Hole Saws. With specifications identical to our standard arbor variety, this product stands out with its bonus feature - a 13mm (half inch) extra-long pilot drill. Perfectly ideal for drilling with extended cutting depth, it greatly complements our Fast Cut Multi Purpose Hole Saws (MPH). The arbor also has an inbuilt set screw making the replacement of the pilot drill a breeze. Designed for 14-30mm hole saw diameters, it's a versatile tool for any power-drilling needs.
