Hardened metal and home shops.

Yeah, but you aren't the average bear there Yogi.

I guess I should have titled it "typical" home shops.
I probably only have 3 - 4 tiny carbide end mills at most. And none of them are ball end mills which I would need for 2 of the 5 slots.

I'm sure I could buy another bit with the proper shank for probably less than what the end mills would cost. I should have known better.
