Chatter while parting off.
Did you try the "power feed and lots o' coolant" with the HSS tools??
Don't think it would work anywhere near as well. The carbide insert has a
molded chip breaker that pulls the chip in from the side walls so they flow
out well. I seem to remember a sickening crunch and broken tool when the
chips bound up in the HSS cutoff tool.
