Titanium Carbonitride, blue grey in color, has a hard, smooth finish which offers improved wear and built up edge resistance. TiCN has good adhesion, toughness, and resistance to chipping and performs well on drills and reamers where moderate temperatures are generated at the cuffing edge. 

·         Hardness (Vickers): 3000 (87 Rc)

·         Oxidation Temperature: 400°C (750°F)

·         Friction Coefficient: .45

·         Thickness: 2-4 microns

·         Surface Roughness (Ramm): .17

Applications: Excellent for drilling and reaming of cast irons, high silicon aluminum alloys, copper, and all abrasive materials. Also a good choice for milling in chip classes 20 and 40 materials. Because of the relatively low oxidation temperature of TiCN, coolant must be applied correctly to control the temperature at the cutting edge. Failure to do so can lead to premature wear of the coated surface.
