Machinist's Calculator
Right Angle calculations-Quickly calculate the dimensions and area of a right angle triangle.
Oblique Triangle calculations-Quickly calculate the dimensions and area of an oblique triangle.
Speeds and Feeds
- Quickly calculate cutting Speeds and Feeds for drills, milling cutters, and lathe workpieces. Calculate between RPM and Feet-Per-Minute or Meters-Per-Minute, and between Feed-Per-Rev and Feed-Per-Minute. Drill Charts and Materials List are usable right in the function.
Counter Sinks & Drill Points-Calculate drill point and countersink depths. Drill Charts usable right in the function.
Bolt Circles
- Calculate X-Y coordinates for equally spaced bolts. You can make the center of the circle any coordinate you need, and place the first hole at any angle.
Sine Bar
- Quickly and accurately calculate precision block stack or angle for use with sine bars or sine plates.
Thread Measure
- Quickly make all the calculations required to measure screw threads using the 3 wire method.
Drill Charts-Quickly lookup Decimal conversions of Inch based Number & Letter Drills, and Tapping Charts for UN & ISO Metric, Cutting, and Coldform (roll) taps. Use the Drill Charts right in the Speeds & Feeds and C'Sink & Drill Point Functions.
Materials List--Material list containing starting cutting speeds for over 200 materials. Use the Materials List right in the Speeds & Feeds Function.
All calculations can switch between imperial and metric with the touch of a button.
Uses an attractive graphical diagram background for easy answer references! No more text boxes and labels! Automatically makes the calculation once enough information is entered!
Designed for Smartphones and Tablets!

Bought this, found fswizard which was free and vastly better. This app is fine, but fswizard is incredible if you're an actual machinist. This app is easier to use, just much more limited.
portrait mode please! landscape is too hard to use 1 handed
great app for machining calculations. easy to use. 👍
Menus are clunky, works well otherwise
Handy, easy and accurate
i use this app every day, very handy. Best app I've ever bought!
I like most of the app. However I think the Acme 3. wire measure function is not accurate at all. This is an important feature for me. Please fix.
Very nice, would be awesome if the was an addition to the app for generating chambers and radius in turning centers. Coordinate based like the bolt circle portion of the app.
Very good. I wish the instructions were clearer for someone, such as myself, that is a little unsure as to what the abbreviations mean. Well worth the price and very useful.
Great app, love the Bolt hole calculator. Only complaint it the pipe tap chart doesn't list hole sizes if you're using a reamer
Used measurement over wires in the first hour , loved it, makes process much easier and faster saving time and money.
This app is AWESOME!!!! I can calculate things faster at my machine than our programmer can on his cad/cam program.
Very useful in the shop. As a QC inspector, I would like to see some added features. For example...the BC section gives XY coordinates based on a given Bolt Circle. How about giving a Hole-To-Hole dimension to check angular spacing of the holes (BC dia, Hole dia, and Angle will give the number) as well as inside and outside dimensions (BC+OneHole Dia or -One Hole Dia) and then a reference number for concentricity (think a BC concentric to a bore or OD...what's the measurement from the hole to the Ref Dia?). Again, for shop use, this App is great...for QC, it could do more. I'm not complaining (hence 5*), just suggesting. Thanks.
It works
Best thing for a machinist use to trig angles
Good app use it all the time
Very helpful it works great and accuracy is good .
Use it constantly. Great
Worked great.
It's ok
Use it every day. Very handy for angles and hole circles. I am a factory maintenance and die repair man and appreciate this apps simplicity. Machinery handbook is gathering dust.
I use the sine bar portion of this weekly. That alone is well worth the few bucks I paid.
I use the trig and sine bar functions everyday. Only problem is my phone gets filthy from using it so much.
Simple and easy to use.
I have a no-contract android phone and noticed that when I use this app it disabled my phones power off capability. Had to remove the battery and power the phone back up otherwise it's a great app. Would like to see a grid pattern calculator with it though.
The only problem is just application icon just shows an Andriod icon with Words Machinist calculator under it.
Does exactly what it supposed to and cuts calculation time bown by a bunch. And for those that rate this app 1 star, maybe learn how to use electronics
Anyone in the machining industry should have this app. It has everything needed to answer regular everyday questions on the shop floor. I use it in the QA department and am constantly sharing with my coworkers on the floor.
Best app at any price, would pay more for all the Math Trade calculators in one ( like the desktop version). IJK for radius coordinates would be cool. And a chart of lettered drills? nearest standard vs metric drill size? Helix Spiral angle of threads? Morse Taper calculation?
