TUSK GRINDING WHEEL DRESSER - Ideal tool for "dressing" up workshop bench grinding wheels. Restores and prolongs the life of grinding wheels by dressing across the width of the grinding wheel, reshaping worn wheels to restore the true flat grinding surface. Features a 36 grit heavy duty diamond coated head with a knurled handle to ensure a secure grip. To restore the maximum performance from your bench grinder, it is imperative grinding wheels are regularly dressed across the width to maintain a good wheel balance and ensure a "true" grinding profile. Performing this regular maintenance exercise will extend the life of your grinding wheel.
