5 Stars
Perfect hole!!!
This tool is the ultimate in hole cutting for metal. I used it to cut 3- 2" holes so far in electrical boxes and it has performed in a stellar fashion! As others have indicated slow and oil is essential but the results are very impressive. I have been using it on 16 gauge steel but I'm sure it would do excellent job on SS or other metal.
