Today’s technological advancements in various industries such as Automotive, Aerospace, Oil and Gas and Medical demand solutions for machining materials which are more heat and abrasion resistant. Such materials prolong the durability of the component but pose high level of challenges during machining. As a rule of thumb, the cutting tool needs to be at least 3 times the hardness of the material to be cut. So, for machining Hardened steel of about 700Hv, the cutting tool hardness needs to be at least 2100Hv. A general carbide cutting tool / insert has a hardness of 1500Hv making it limited to machine such hard material.

Tungaloy is one of the very few companies in the metalworking world that produce a material called Sintered CBN or Cubic Boron Nitride which has a chemical compound of Boron and Nitrogen which are pressed under extremely high pressure and temperature with other binding materials to form a material which is the second hardest substance known to mankind, after Diamond. With its hardness over 7000Hv and a very high thermal conductivity, CBN is increasingly used as an important cutting tool material for high-speed machining of Hardened steel, Sintered material, Cast Iron and Inconel.
