I am trying to make a 3 axis machining operation in bobcad to mill what is essentially a V shaped channel. The included angle of this is 120 degrees so I want to use a 120 degree end mill to machine this slot. The slot is wider than the mill so it requires multiple passes.

I am trying to select a chamfer end mill in the 3 axis tool crib in bobcad but all that I can get to come up are flat end mills. The drill point end mills show up in 2 axis operations but not in this 3 axis operation. How can I get them to appear in the 3 axis operations?

thanks much
Brian
