RPM = revolution per minute(rev/min)
SFM = surface feet per minute(ft/min)
DIA = diameter of drill (inch)
IPR = feed rate (in/rev)
IPM = inch per minute penetration rate
The recommendations for speeds, feeds and other parameters presented in this chart are nominal
recommendations and should be considered only as good starting points.Speed and feed
reductions (20% reduction in speed and 10% reduction in feed) are recommended.
