I understand that one can buy HSS inserts that fit in the tool
holders for carbide. But I can not locate a source. Any one know
where one can buy them?

I don't want to get into any arguments but I grew up and did my
apprenticeship in the High Speed Steel days and I must say that the
way we were taught to grind high speed tool bits resulted in a
substantially different tool than what I see used with "insert" type
tool holders which I suspect might be better for turning something
like plastic.
