It's a DPGT and it does it in titanium with CNMG and Brass with CNMG and Aluminum with CNMG, DPGT, HSS. The insert I'm using now roles the chip off without any problems. And the pattern is the same in all materials, even stainless. When I run stainless I use a very high dollar insert that cuts wonderful on the other machine, cuts fine on this one just leaves ridges.
