We call them inserted tip tools or Oland tools

I thought the Oland tools were square bar HSS ? ('60s lathe tooling).
We're talking here about '80s lathe tooling - replaceable carbide
squares or triangles, pre-sharpened at the factory.

IMHE, carbide tooling is too brittle for most woodturning. A big catch
and you'll chip it. Spending money on better carbide grades can improve
this though.
