### Cutting Speeds & RPM Calculations

The RPM formula for tapping is no different from the other formula we have been using, but the consideration mentioned for tapping must be made before we actually do any power tapping. Until you know how the tap will operate under your conditions, start with 1/3 to 1/2 the calculated RPM and gradually increase the RPM to the capacity of the
