4142 Pre-hard?
#7
Ken, I only need to mill some flat stock to reduce the width. I have a handfull of carbide end mills so that isn't a problem. My main concern is in threading a couple of holes. The only 8-40 tap I have at the moment is carbon steel.

The stock is only 3/32" thick, but with my luck.....
