Machinist use

This app is perfect for machinists. It's very helpful and accurate as well. I love the variety of rate calculators. This app serves several purposes and is quite useful. It's great if you don't want to have to memorize formulas and ways of calculations anymore. You can just punch numbers in and they'll do the work for you.

Milling Only ,

This is NOT for turning applications

The app only supports data that is used in milling. It DOES NOT produce any turning data. Decent app for milling, but there is no option for imperial or metric measurement.
