    Not sure that I have ever knurled 4140.
    How well does that work?

    Need to go "cut" type for that?

    Ox, I should clarify, when I knurled pre-hard 4140 before, it was with a forming tool from Accu-Trak, Straddle-type with convex knurls. Worked very well, knurled about a 3" length on 1" nominal OD (turned to 63/64", for 64DP knurl). It was at least 200rpm, 0.005ipr axial feed, but I know I bumped it up a bit at the control.
