My favorite calculator to use for everything. Also super handy if you're a machinist. The thread calc is correct everytime. Great for bastard threads not in the machinerys handbook. The bolt pattern is awesome for readouts that dont have that function. And the bolt pattern throws out your center to center distance handy for manually laying out a pattern. No more calculating cords. Quick feeds and speeds calc. The trig function works well.

The only problem I have is that it's not an upgrade to the MC2 version. Not cool at all. Otherwise it's awesome.
