Simple but what I needed

Just calculates feeds and speeds, but gives you the option to calculate using different combinations of known information. Not clever enough to cope with variable tool or stock materials. You have to get the feed per tooth for any material and cutting rpms from charts from the company that made the tool. At least that is cutter specific, taking into account geometry and cutter material.

Thought it would be better

I thought that I’d be able to find ideal material cutting rates but alas not...

I bought two apps for the same reason, this one is the winner, simple, easy to use and most efficient!
