sharp HSS can take off
curls of steel that just about float in the air and can be the
difference between a fit and a scrap part. can carbide do that?
no it cannot, because its edge is not *sharp*.

Uncoated carbide can. Most hsm types purchase coated
carbide, and the coatings don't stick to a dead sharp
edge. The manufacturer gives those edges a 'hone'
or turned-over edge.

Uncoated carbide inserts can be purchased that are
razor-blade sharp.

thanks Jim, noted

But the hss does seem to be the best overall for
home shop use, in general. The versatility of

being able to profile unique shapes with a simple
pedestal grinder is real handy.

yup...
