Does wonders for your grip strength too. You can also trim it up with an abrasive wheel for final fit. Use the abrasive cutting disc. Remember that with S.S. it work hardens. Get serious when you want to grind or drill and make the sparks or chips fly. If you don't you will have a tough time especially with the drilling. See Tony Bingelis, "Firewall Forward" page 100. To give you an idea, S.S. is often used in the mining industry for liners in material handling systems where the product is highly abrasive. It hardens off as it is used and forms an abrasive resistant surface. Ian Crowe.
