Machinist Calc™ Pro

Advanced Machining Math and Reference Tool

Ideal for machining pros 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.

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 all the functions of the Machinist Calc (Model 4086) plus right triangle math, trigonometric solutions, 3-Wire measurements and more.

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

Includes a rugged shock, dust and moisture resistant Armadillo Gear protective case.

Built-in Functions and Calculations:

• Speeds and Feeds calculate for milling, turning and drilling; cutting speed, spindle speed (RPM), feed rate (IPM), cutting feed, feed per tooth/chip load
