Now you've done it Rob - I've ordered one
It just looks too handy having the material tables as well as the calculations all in one place - I just hope it lives up to my expectations
.... anyone want some broken carbide end mills .....

That's a pretty limited materials list. They don't even have the lowly 1018 in the list or 12L14.

Hi Ed
I suspect the list is kept short so that the user is not trawling through a list of some several thousand material possibilities , The steels are grouped as low/medium/and high Carbon so you need to know what group your material falls into .
The user manual gives Low Carbon Steel as steels with a hardness of 120 -170 HB , 1018 has a hardness of 126 HB and is classed as a Low Carbon Steel .
Medium Carbon steel as steels with a hardness of 160 - 210 HB , 12L14 has a hardness of 163 HB so falls in the overlap of the low /med selection , being leaded I would select the
low Carbon steel option .
