I don’t know if other people do this, but on my lathes I only use HSS for cuts between .0001” (i.e. “one tenth”) and about .008”. Between roughing, medium- and fine-finishing, I find carbide inserts to be amazing! And yes, I am using balanced cutting. The HSS is great for when I failed with the balanced cutting.
Regarding HSS tool bits, I am always pressed for time, my bench grinder is a hunk of junk, & even if I did have the time & equipment to grind my own HSS, I am sure that I could not meet or exceed the quality that one gets on a carbide insert.
