tools

The Machinist Calc Pro 2 has three built-in Tool Types that can
be used to determine tabular Feed and Speed values.
You can scroll through the available Tool Types by repeatedly
pressing the L key, or by pressing the + key or - key to

rpm (SpINDlE SpEED)

RPM is the rotational speed of the spindle in revolutions per
minute. In a milling machine or drill, the Spindle Speed is the
rotation of the attached cutting tool. In a turning machine, it is
the rotation of the attached workpiece. RPM can be calculated
given values for Diameter and Cutting Speed.

rpM - Basic

Calculate the RPM when milling with a 0.375" bit at a Cutting
Speed of 300 sfm (surface feet per minute):
1. Enter the bit Diameter:
