- Metric and Imperial units (mm, inch)

*** Milling ***
- Calculate RPM given the Cutting Speed and Tool Diameter
- Calculate Tool Feed Rate given Feed/Tooth, Tool Diameter and number of tool teeth
- Calculate Machining Time given the Feed and Cutting Length
- Metric and Imperial units (mm, inch)

*** Drilling ***
- Find RPM given the Cutting Speed and Tool Diameter
- Find Feed Rate given the Cutting Feed (inch/rev) and RPM
- Find Machining Time given the cut length and feed rate
- Metric and Imperial units (mm, inch)

Customer Reviews

$5 and still ads


The app itself is amazing and it does everything I need it to. It is just really annoying having to pay $5 for an app with a permanent ad at the bottom, that's why it's 3 stars not 5.

Really useful App… The best of its kind that o have ever seen. Very easy to use with very useful reference tables that usually I need them in the shop… I love having my phone as a tool at my work..
Feedback: It would be nice if you add more speed and rate data for other materials ..

Handy App… NICE

I really recommend this App for those of you who are in machining field.. I wish I had this App 5 years back when I started my… job
Beside its help in regular machining work, I learned a lot on the basics of machining from this App.. A simple but very useful tool
