Now you've done it Rob - I've ordered one   Thumbsup

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  Yikes


.... anyone want some broken carbide end mills .....  Slaphead

That's a pretty limited materials list. They don't even have the lowly 1018 in the list or 12L14. 17428

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 .
