Does HSS leave nicer finish when sharp than carbide on these materials?
Considering tiny pieces of the tips broke off the carbide cutters I have,
I can't really test this anymore.-

Carbide is fine under the right conditions. My old 10" South Bend
lathe is on the border where sometimes it works and sometimes it
doesn't. It's been better since I ground the uneven wear off the
compound slide and tightened the gibs. I get nearly a mirror finish
with carbide on stainless steel.
