What I have for sale is a new, never sold, AS 15 air grinder. It comes complete with the 3" and 5" backing plates for sandpaper discs. Great for metal work and grinding welds. I have seen, grinding discs, flap wheels, Scotchbrite discs and the like used on this tool. It's tough built and heavy duty. Regular $179 on the MAC website. $79 + shipping. It should fit in a USPS prepaid box for $14.35 or standard shipping which ever is less. Please pm if interested. High-Speed Rotary Pistol-Grip Sander 5"
