The Machinist Calc Pro is the first dedicated handheld 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
