Got some carbide inserts off eBay, nice and cheap, for playing about with. The main reason I got them was to use in a flycutter that I'm making (a T-shaped one like the Japanese guy with the web site made). They're triangular with a hole in the middle. I notice that there's no relief - if they were mounted on a lathe tool, set horizontally, the face/edge towards the workpiece would be vertical rather than sloping away a bit. Are these intended to be used on a lathe, or are they for something else?
Having received them, and looking at the selection of broken lathe tools I inherited from a mate, it ocurred to me that I could braze an insert onto one and make a long-lasting tool. Can these carbide thingies be ground to a suitable shape and still work?
