Jul 24, 2019 · 4140 is very nice to machine and the pre-hardened version is a real winner for surface finish. Try 400 fpm for roughing, .020" feed and as big a DOC as you have horsepower for. I was doing .19" DOC in a 3" diameter pre-hardened bar while testing a new Iscar tool (.032 nose rad) and that was about the limit for my 10hp spindle.
