The new Tormek EzyLock shaft kit includes a self-tightening knob to secure the grindstone. No tools are required and you don’t need to exert any pressure on the nut to secure the grindstone. EzyLock makes it very easy to change grindstones, from the standard aluminium oxide to either of the specialty stones. The shaft and washer are made of stainless steel. The nut is also stainless steel for the T-7 and a composite material for the T-3. The kit includes an EzyLock Shaft, EzyLock Nut, two replacement nylon bearings, cross pin, stone washer and drive wheel washer. The MSK-250 fits the T-7, Tormek 2000 and any 250mm motorized Tormek (pre-95 models require modification). The MSK-200 fits the T-3 and any other 200mm Tormek machine.
