Gator 1" x 1" x 6" Grinding Wheel Dressing Stick is made of aluminum oxide and has a 24 grit. It is used to dress grinding wheels and remove burrs and other imperfections. During normal use, bench top grinding wheels become clogged with particles and begin to wear unevenly. Use the dressing stick to clean and reshape the surface of your wheels. This will extend the life of your wheels and improve their performance. The dressing stick can also be used to sharpen hand and cutting tools.
