84 Engineering Contact Wheels Precision ground contact wheels from 84 Engineering for the Shopmate 48" and Shopmaster 72" Grinder. Perfect for general metal shaping & stock removal to knife handle sculpting and profiling. The standard 19mm spigot included with the wheel allows for fast and efficient changing between your contact wheel and flat platen. Contact wheels are great for rapid stock removal as the smaller diameter of the wheel opens the grain of the belt, exposing fresh grit that simply cannot be utilised in flat platen grinding. The aluminum hubs are precision CNC machined, then coated in a premium, abrasion-resistant urethane rubber – all completed in-house. The wheels are then ground concentric for a perfectly smooth and vibration free grinding experience. Sizes 4" 5" 8" Special Requirements Compatible with all Shopmate and Shopmaster grinders except for old Shopmaster 72" grinders with a 300mm tooling arm. This tooling arm can be bought here.
