Tool steel taps and dies like M2 or Tungsten are for production uses or for someone looking to get lots of life out of a tap or die. V. TUNGSTEN ELECTRIC COY. Prior to 1945, tungsten carbide was prepared by melting tungsten, carbon black and metal oxides at a temperature of2000 °C but the tools made from this metal were found to be far too brittle for industrial use. Tungsten carbide is the most widely used type of high-speed machining (HSM) tool material produced by powder metallurgy, consisting of hard carbide (usually tungsten carbide WC) particles and a softer metal bond. It has many unique properties, for example, the melting point of Tungsten is the highest of any element yet discovered–it melts at 3422C (6192F)!
