Increase strokes per min (45 FPM)
decrease rotary feed
to.010 based on 11 through 19 DP
.016 based on 1 though 4 DP
If you purchase Premium tool steel then you can increase Strokes per min and feed.
otherwise the low grade tool steel will get chewed up.
Plus a rex 76 or M45 tool steel like recommended
be fore will reduce the # of sharpening per cuts.
hope that helps
