Galaxy Wheels give you the fast, cool cutting efficiency of diamonds, plus a smooth, true-running surface that never needs dressing. Galaxy wheels give you lasting service because of their quality construction. The diamonds are held on a heavy steel ring by an extremely hard, nickel alloy plating for durability. The ring is mounted on a tough glass-filled polyester core, making Galaxies a smooth, quiet running wheel.
Galaxy wheels have a 1" arbor hole. Bushing are not supplied with the wheels.
7-5/8" wheels takes two 3/4" wide bushings.
