Tormek MSK-250 Stainless Steel Shaft w/Ezylock upgrades your Tormek 2000 or T-7 Sharpening System to allow "no-tools-needed" grinding wheel changes. This innovative shaft acts as both a nut and washer, featuring a special pitch on the left-hand thread that tightens the nut to the correct torque as the wheel rotates. When removing wheels, simply turn the stone clockwise and the Ezylock automatically loosens. Turning the Ezylock counterclockwise by hand causes the grindstone to tighten automatically when the unit restarts, making it incredibly easy to switch between the standard aluminum oxide stone and any of Tormek’s specialty stones. Crafted entirely from stainless steel, including the shaft, washer, and Ezylock, this kit also includes two nylon bearings for smooth operation. It fits Tormek T-7, Tormek 2000, and all older models designed for a 250 mm (10") stone, delivering durable and reliable performance straight from Sweden. Model Number: MSK-250
