Always interested in more tooling, shoot me a pm with specifics.I have a 1.5" HSS shell mill if you are interested.
I will get a photo over the weekend. What is the slowest speed on your mill? It may be to high for HSS at 1.5" dia.Always interested in more tooling, shoot me a pm with specifics.

Are you a haas reseller or something????My book is about lathe tooling, not indexable milling cutters. Sorry.
One of the things I like best about the Haas indexable tooling is that they are very clear what material the insert is best suited for. Most of the other insert manufacturers assign a cryptic and proprietary grading code that is only helpful in understand what materials it will work well with if you have their 4" thick tooling catalog.
For instance.

I have no affiliation with Haas. You seem offended that I would post a suggestion here. And you are incorrect that their insert shapes are "nothing special" - their inserts are proprietary to Haas, but generally have thicker and more robust geometry compared to the industry standard inserts. And I have had in-depth discussions with Haas about their tooling QC program and I'm satisfied that they are on-par with Iscar, Sandvik, et al with respect to insert pocket tolerances, as well as the durability of their inserts. I can not say the same about Shars as you can see in this video where I actually test a Shars face mill.Are you a haas reseller or something????
Haas is not making their tool bodies nor inserts. There is nothing special compared to anyone elses insert/shape, And their P M K N symbols are the exact same as every one else uses??? Every kennemetal, mitsubishi, sumitomo, iscar, sandvik, and lovejoy insert box I have has P M K or N on it.
Second, while the OP picked probably the best face mill insert style he could for the machine, its still to big for it. I would be dubious with .400 depth of cuts on steel.
If you do have issues drop a few inserts and slow the feed down. Even a single insert acts as a nicely balanced fly cutter.
Many of the used cutters out there are beat to hell and new imports have questionable pockets, both leading to uneven insert height and the resulting surface finish.
1.5" cutter at 100 sfm would be 255 RPM so your mill could run a 1.5" tool in steel.8 spindle speeds from 180 to 3000 rpm
