Looks like a punch / tooling die. I would recommend using Cermet inserts and keeping your SFM between 65-80 run it dry take a decent cut engage the full nose radius this will remove the heat in the chip and keep a mirror finish run your IPR at .0025 - .004 for finish and .005 - .008 on rough depending on your rigidity
