I know carbide is brittle and very hard but is there a way a woodworker with typical tools could cut a 1/4" diameter solid carbide tool like the one pictured below in half? What would happen if I took a metal cut off disc on my 4.5" grinder to it?

Try a Dremel diamond cutoff blade. Diamond stones will sharpen carbide so the blade should cut it.
Most carbides have a hardness between 90 and 93. It will be difficult at best to cut this
I have cut some of my carbide gravers using a diamond disk (Dremel type), but creating a groove all the way around, then place the bit in a good solid vise, wear eye protection, and smack with a hammer side ways. It will shear from groove to groove, and be a little coars on the new break.Quote:

Ditto what Mark said. I cut carbide and HSS bits by scoring all the way around with the Dremel and then breaking them. Put them in a vice and put a cloth over them. Then grab them and break or hit it with a hammer. The cloth keeps things from flying all over and/or hitting you.
