Sounds like aerospace "excess inventory". Who else can afford to scrap something like that because it costs more to keep it on the books?I wo
I wonder if it got lost in shipping and went to scrap?

Wish I had a scrap source like that, just not willing to live in southern California to get one. Maybe something near Boeing.I think that’s the case. They have a lot of titanium as well. The 303 took some digging. Most of the SS they had was 304 and 316.
I just tried 0.004 DOC and cut only about a half inch before the spindle stopped. (Better finish, though!)Without flood coolant in 303SS I would run about 200 SFM (about 300 RPM on 2.5'' material). My go to insert for SS is the Mitsubishi DiaEdge DCMT xx.51 MV where xx is the size, I assume 21 for your tool holder. Your feed rate at 0.0015 should be good for finishing at about 0.005 DOC. If your machine is rigid enough, a bit more aggressive on the roughing cuts would be in order.
I have cut about 1/4 mile of 303 SS in the last 6 months or so and these inserts have proved to do a nice job.
Well a bit more..... OK a lot more . But I'm surprised that your machine stalled at 0.004 DOC. You were in low gear?I assume you're cutting 0.005 with more than 250w?
