Formulas 1. RPM = (318.47 • M/min) / DIA

2. M/min = RPM • 0.003 • DIA

3. IPM = RPM • mm/rev

where:

where:

RPM

= revoluƟons per minute (rev/min)

M/min = speed (M/min)

IPM = feed rate

M/min = speed (M/min)

RPM

= revoluƟons per minute (rev/min)

RPM

= revoluƟons per minute (rev/min)

DIA

= finish diameter of drill (mm)

DIA = diameter of drill (mm)

mm/rev = feed rate (mm/rev)
