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 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.
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, number of Teeth and Radial Chip Thinning adjustment factor
Built-in Drill and Thread Size Tables - save time and steps (Compliant with ANSI/ASME B1.1-2003 and ANSI/ASME B1.13M-2005)
Enter Numeric, Fractional, Metric Thread Sizes and Drill Sizes - and display tap, roll tap, close and free fit drill sizes plus pitch, major and minor diameters
Right Triangle Math - plus trigonometric functions
Drill Points - enter the cutting angle and drill size to calculate the drill point cut depth
Bolt Pattern Hole Layouts - enter start angle, number of bolts, diameter and optional x, y offset; calculate x and y coordinates. Find center-to-center spacing for bolt pattern layouts
3-Wire Measure - enter Wire Size (or use calculated Best Wire size) and 3-Wire Measurement to calculate pitch diameter
For efficiency-minded Machinists, Setters, Tool and Die Makers, Supervisors, Shop Owners

I had the chance to handle one of these at IMTS 2014 on Tues. It is still my favorite calculator. I am currently using the machinist calc pro and I can't wait to get a pro2.
Extremely useful resource
User: Scott Rackley, Tool Maker, Tool Designer from Chattanooga, TN
I design tools for a major corporation. I use this calculator every day. Once you learn all the tricks, calculations are a breeze. Recommended for all tool makers, machinists, and apprentices.
Pays for its self
User: R Blocker, machinst from Spokane, Wa
I will say this is the best set-up calulator on the market today. 25 years as a machinist,The Machinist Calc Pro has paid for itself in the first week . NO KIDDING
Does its job well
User: Mark Fischer, Machinist of Taylor Machine, Inc. from Blaine, MN
Good product for professional machinists alike.
User: Sean Farrell, Student Machinist from Charlotte, NC
As a machining student this tool has been invaluable with helping a rookie with all my calculations!

User: Rex D. Banet from Jeffersonville, IN
This Calculator is extremely useful and user friendly. I purchased a total of 8 for our Toolmakers and most have had the trade for 25 + years and are impressed and continually use the calculators.
User: Paulo Fernandes, CNC Operator of Flowserve from Etten Leur
Very nice product, and need every time to work. Thank you so much
User: J. Douglas Bowman, HTEC Director of Vincennes University from Vincennes, Indiana
I have found the Machinist Calc Pro to be an ideal calculator for the machinist on the shop floor. In a matter of seconds I can easily do everything from calculate speeds and feeds data and determine tap drill sizes, to working trig problems. And jumping between inch and metric is a breeze. It is also ideal for CNC programming, so I encourage everyone that I train to add this calculator to their tool box in order to save time and be more productive.
User: Tim Markoski of CNC Machinist Software from Houston, TX
As someone who develops software for a living and has written Machinist Calculator Applications for mobile devices, this unit is simply awesome.
User: David Crabb, Journeyman Machinist of HMF from Manitowoc, Wisconsin
No more carrying around Machinist Hand book and other charts! This calculator does everything! Makes everything else seem like a 30 year old calculator! Wish I would have had one 20 years ago! Even comes with a great case!Thanks again CI!
User: Jim Vyhlidal, Quality of TRI-V Tool & Mfg. Co. from Omaha, NE.
Has functions that our Machinist Handbook does in the Machinist Pro calculator.

I have been a Journeyman Tool and Die Maker for 10yrs. This calculator has most of the calculations you need on a daily basis. Now I don't have to look up charts or do trig. formulas. I wish I had this 10yrs ago.
