I would try is using the shortest end mill possible for your required depth of cut, installed directly in an R8 shank to get as much rigidity as possible at the tool. That indexable looks to have a lot of stick out. I usually leave 3% of the tool diameter for a finish pass which has always worked well for me. From what I can find, that looks to be steel used for molds ?. I cant find it in the list for HSMadvisor. Your chips look to have a blue tint, so it looks like your SFM is correct.

Thats probably a good idea. I will order some r8 collets to try mounting the tooling directly in the spindle. Actually the tool stick out is less than what I need. I need 35mm since that is the material thickness, It is 32mm.


The material is a common construction steel around 150-190 HB.
