The 

Machinist Calc™

 Machining Math and Reference Tool (Model 

4086) and the 

Machinist Calc™

 Pro Advanced Machining Math and 

Reference Tool (Model 4087) both provide fast, precise solutions 

for your every day machining calculations. With the 

Machinist Calc/

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.
This User’s Guide has definitions, examples and instructions 

for both calculators. Information specific to a particular model 

is indicated in the Table of Contents and throughout the User’s 

Guide.
Both calculators will provide you with 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 

 

• Bolt Pattern hole layouts

 

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

 

 

• Decimal Inches/Mils

 

 

• Feet-Inch-Fractions

 

 

• m, mm, cm

 

 

• Area, Volume and Weight

In addition, the 

Machinist Calc Pro

 (Model 4087) has:

• Advanced Built-in Drill and Thread Size reference tables

 

• Drill Point Cut Depth solutions

 

• Wire Sizes and 3-Wire Measurements

 

• Advanced Bolt Pattern hole layouts with center x, y coordinate

 

• Right triangle math

 

• Trigonometric solutions
