Cutting through cobalt chrome
Another significant consideration is that cobalt chrome is very heat-resistant with low thermal conductivity. During cutting of standard steels, heat generally is evacuated through the chip. However, with cobalt chrome, heat does not generate into the chips. Because of this, the heat concentrates at the cutting edge of the tool," said Doiron.
