Machinist Calc Pro Advanced Machining Math and Reference Tool Calculator

The Machinist Calc Pro has fast, precise solutions for your everyday machining calculations built into a shop-tough and cost-effective handheld calculator. It offers 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. It also has a drill point function where you can enter the cutting angle and drill size to calculate the drill point cut depth. Built-in functions include calculations for milling, turning and drilling (including cutting speed, spindle speed, cutting feed, feed per tooth/chip load, and more); bolt pattern hole layouts; 3-wire measurements; and trigonometric functions.

  • Reduce wear and tear on costly cutting tools
  • Works in and converts between all dimensional units
  • Includes rugged, shock-, moisture-, and dust-resistant Armadillo Gear case, quick reference guide, complete, easy-to-follow user guide, and two 1.5 Volt LR-44/A76 long-life batteries
  • Convenient data look up for drill and thread sizes
  • Speeds and feeds – calculate for milling, turning and drilling; cutting speed, spindle speed (RPM), feed rate (RPM), cutting feed, feed per tooth/chip load
  • Built-in advanced drill and thread size tables – save time and steps (Compliant with ANSI/ASME B1.1-2003 and ANSI/ASME B1.13M-2005)
  • Bolt pattern hole layouts – enter start angle, number of bolts, diameter and optional x, y offset; calculate x and y coordinates
  • Enter numeric, fractional, metric thread sizes and drill sizes – and find tap, roll tap, close and free fit drill sizes plus pitch, major and minor diameters
  • Right triangle math – plus trigonometric functions for fast, accurate solutions
  • Drill points – enter the cutting angle and drill size to calculate the drill point cut depth
  • 3-Wire measure – enter wire size (or use calculated best wire size) and 3-wire measurement to calculate pitch diameter
