Formulas 1. RPM

= (318.47 • m/min) / DIA

2. mm/min = RPM • mm/rev where: mm/min = mm per minute (mm/min) RPM = revolutions per minute (rev/min) mm/rev = feed rate (mm/rev)

where: RPM = revolutions per minute (rev/min) m/min = speed (m/min) DIA = diameter of drill (mm) 3. m/min = RPM • 0.003 • DIA where: m/min = speed (m/min) RPM = revolutions per minute (rev/min) DIA = diameter of drill (mm)

IMPORTANT: The speeds and feeds listed above are a general starting point for all applications. Refer to the Coolant Recommendation charts for coolant requirements to run at the recommended speeds and feeds.
