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

SETTINg FracTIONal rESOluTIONS
The Machinist Calc and Machinist Calc Pro are set to display
fractional answers in 64ths of an Inch. All examples in this User’s
Guide are based on 1/64”. However, you may select Fractional
Resolution to be displayed in other formats (e.g., 1/16”, 1/32”, etc.).
The methods for permanently and temporarily changing Fractional
Resolution are shown in the following sections.
Permanently Set Fractional Resolution
To permanently set the Fractional Resolution, you must be in
