Re: VHM carbide cutter - all lenght from hard metal? Or just cutting part?
Sorry , mu english is not perfect. I mean - cutter have 2 parts: one which is round cylinder and one it was for cutting: does both of materials "black one" half part and "silver" half are from same hard material? I supose that black darker cutting area is somehow extra coated - but does the whole cutter are basicly from one material (except thin coat if any on one half who appear black or other colour?) Thanks
Re: VHM carbide cutter - all lenght from hard metal? Or just cutting part?
That depends on the size and price of the cutter.
It is most likely that the black colour is a coating over the silver part - which may be HSS if it is really 'shiny silver' and not grey. Grey would be carbide.
