I'm not going to waste my time plowing through *all* the used hay in
this thread such as:
"Ya have to have a really rigid machine to use carbide." I use it on
a Chinese 3-in-1 for the vast majority of my turning. I use HSS when I
want a special shape cutter.
"Carbide can't be as sharp as HSS." I use uncoated carbide TNMP-321
inserts. When I want them *really* sharp, I hone the edges on an
Easy-lap diamond hone.
"You need to turn at really high speed to use carbide." You *may* run
carbide at much higher speed than HSS but you don't *have* to. I run it
at whatever speed I feel comfortable and my machine can handle.
There's more but I suggest you try it for yourself.
