Expander Wheel Kit Includes 1 Band Of Each Grit
Product Review (submitted on July 22, 2012):
I have used this system for everything from removing mill scale from steel before welding to sharpening tungsten tig electrodes to polishing hardened steel aircraft tools. The ease of changing grits is excellent (except for the Scotchbrite bands which are somewhat tight). The slight "give" of the rubber wheel makes getting a smooth surface much easier than with hard grinding wheels. I highly recommend them, but feel they are a bit overpriced.
