Little calculator for machining and drilling

For those interested, who don’t already have it, here’s a great
little program. Here’s a link:

It’s a tiny little app - no install routine, even, just put it in a
directory. It calculates cutting speeds and feeds for various tools
and metals, and quite a few other things. It’s worth it’s weight just
for the extensive info on tap drills. Very nice little calculator for
machining and drilling of all kinds.
