Ejector Arbor 16-30Mm Mc Hole

All arbors are hardened for maximum strength. Large arbors, for holesaws Ø32-210 mm, have drive pins to transfer large cutting force from the holesaw to the power unit. We recommend not to use arbors with 9 mm (11/32") shank for hole saws above size 100 mm (4"). HSS Pilot drill is included with all arbors. New patented Power Driver™, eliminates play and increases the strength of the holesaw by redistributing the load from the thread to the solid cap.
