What's New

Bug fix (key id assignment) for X devices.

App Description

The Machinist Calc Pro 2 now includes materials and tool settings combined with DOC and WOC to solve all your speed and feed calculations for face, end or slot milling plus turning, drilling and boring. It also gives you step-saving drill and thread chart look-ups, right triangle solutions and bolt-circle patterns.

And while perhaps obvious, if you change from an iOS device to a non-iOS device, you WILL need to buy a new license as they are incompatible.
