App Description

Ideal for machining pros, machine setters, tool and die makers, production engineers, shop managers and shop owners who want to increase productivity and profits in the design, layout and set-up stages of production and reduce wear and tear on costly cutting tools.

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.

The Machinist Calc Pro is the first machining math and reference tool to provide a complete assortment of machine shop solutions. It has more complete Thread data than the Machinery's Handbook, including step-saving Thread and Drill Size chart look-ups, speeds and feeds, right triangle solutions, bolt patterns and much more.

Spend more time machining and less time looking up specs and data in books, on charts or in computer programs.
