Ahm no 'spert, but...
I think you gotta *grind* carbide. Fwiu, that's how cutters/drills are made
to begin with.
"Green wheels" are what we use to make lathe tools out of carbide blanks.
They wear very fast, but remove carbide relatively rapidly.

I've got a small project to do, where I want to turn down the O.D. of
some rock drills by .080".
The problem is they are carbide inserted tips. Kinda as if you'd take
four cemented carbide toolbits and make a countersink out of them.
Don't have a toolpost grinder, and not thrilled about all the carbide
dust anyway.
Someone once mentioned a pressed diamond insert available.. would this
be the way to go, or ceramic, or whatever?
Does anyone here have any experience in turning carbide?
Hope I'm not gonna be at the mercy of the Kennametal or Sandvik
salesman...LOL
Any suggestions are appreciated.
