Just recently sold mine, but had it for about a year and a half. I did mostly small stuff related to pistolsmithing and smaller projects, but once I did push the machine a bit hard. I had a 3/8" carbide rougher hogging 1" thick cold rolled steel. DOC was 1" and full width. VERY slow feed, and lots of lube but the mill handled it. I would NOT recommend a steady diet of things like that, but the mill can handle it occasionally if set up properly. Even though I now have a larger mill I think I'm going to regret letting my PM25 go. It's a good little mill.
