Tungsten and boron carbide should be much harder than any ceramic, though I have had similar experiences with carbide drill bits. I wonder what exactly "carbide" actually means sometimes.

    Most carbide I've run into is usually around 65HRC. The ceramic is have in my lathe right now is 95HRC. Its a significant difference. Its brittle, so it doesn't like interrupted cuts, but it loves heat and speed that would cook carbide in seconds.
