Recommended Speeds and Feeds (metric):

mm/min = RPM • mm/rev
M/min =RPM • 0.003 • DIA
RPM = M/min • 318.47/DIA

SPEED AND FEED RECOMMENDATION EXAMPLE: If recommended speed and feed is 61M/min and 0.20 mm/rev for a standard lenght holder, then the speed and feed using a 3xl holder in the same application would be 45.7 M/min and 0.18 mm/rev.

Recommended Speeds and Feeds (inch):

IPM = RPM • IPR
SFM = RPM • 0.262 • DIA
RPM = SFM • 3.82/DIA

SPEED AND FEED RECOMMENDATION EXAMPLE: If recommended speed and feed is 200 SFM and 0.008 IPR for a standard lenght holder, then the speed and feed using a 3xl holder in the same application would be150 SFM and 0.007 IPR.
