              These inserts are composed of titanium carbide (TiC) and titanium 
              nitride (TiN). They are suitable for a wide range of finish and 
              semi-finish turning because of their excellent resistance to oxidation, 
              negative affinity and high temperature hardness. Applications  
              Finish turning and boring of gray cast iron. Turning of ferrous sintered metals.
  Semi-finish and finish turning of steel.
