Yep, i like to use Sandvik R390 inserts on my mills. If the chips aren't coming off red hot, you're not pushing it enough. This insert doesn't like coolant.
First step is cut right to left so chips nearly all fly backward. if facing cut the back part first.
I do have a couple plexiglass guard that bolt to the back of the vise, and i have a couple piece of scrap sheet metal. Works sometimes, other times not so much. Then i just stand back.
If you're using regular carbide EMs, a fogless mister can reduce the ships temp. by a ton. I posted my build, I see several others have done the same.
