Cobalt

• Provides better wear resistance in hardness and toughness compared to HSS
• For use in high-tensile alloys, titanium, cast iron, Inconel and high-nickel stainless steel

Coating Advantages:

Black Oxide

• Retains lubricants to aid in wear resistance and chip flow

Bright (Polished) Finish

• Improves chip flow of soft and low carbon materials

TiN

• Increases lubricity and heat resistance. Allows increase in machining speeds of 25 – 35%.
