So far this has worked great I run it at the slowest speed on my drill press with minimal pressure just enough to see it's cutting properly. I have only cut 2 holes in .049 Stainless Steel material so far but I have many more to go. I will update this recommendation if things don't work out. The big issue with these cutter are the expense factor at $28.00 bucks this cutter is outstanding considering they can sell for over $70.00 bucks. Stainless Steel is tough to drill and cut holes in using this tool on other materials should be a cake walk. At this time I can recommend this tool.
