The Machinist Calc™ Pro Advanced Machining Math and

Reference Tool (Model 4089) provides fast, precise solutions for

your every day machining calculations. With the Machinist Calc Pro

you will spend less time looking up your most-needed calculations

on charts, in books or on the Internet and more time machining.

The Machinist Calc Pro gives you hundreds of machining-specific

calculations, including:

• Cutting Speed, Spindle Speed (RPM)

• Feed Rate, Cutting Feed, Feed per Tooth (Chip Load)

• Built-in Drill and Thread Size reference tables

• Drill Point Cut Depth solutions

• Wire Sizes and 3-Wire Measurements

• Bolt Pattern hole layouts with center x, y coordinate

• Right triangle math

• Trigonometric solutions

• Work in and convert between U.S. and Metric units, including:

• m, mm, cm

• Decimal Inches/Mils

• Feet-Inch-Fractions

• Area, Volume and Weight

Note: The Machinist Calc Pro calculator Model 4089 and User's Guide are

designed for machinists who work with metric drill, screw and thread sizes

and metric thread tolerance classes. The calculator can be used for non-metric

applications, so some examples for working in U.S. units – numeric, letter,

and inch drill sizes and numeric and fractional thread sizes and classes –

are included in the Appendix of this User's Guide.
