Matco Mini Surface Prep Tool Kit - MT1644K. I used it once or twice and its sat in my tool box ever since. There are some marks on the body from dropping it in the tray. As far as I can tell, Matco does not make a set like this any longer. They make a battery powered version that does not come as pneumatic not with discs and adapters. Trigger is variable speed using dial on top of body. This kit is idea for the removal of gasket material, surface deposits, rust, and grinding welds in tight places.
