'Composition: A multilayered coating over a hard, cobalt-enriched substrate. Application: Best applied in tough, fairly hard, 35 to 45 HRc, alloy and bearing steels. This unique grade offers a substrate that combines hardness and toughness, and a coating design that resists crater and abrasive wear. Can withstand interruptions. Use for moderate roughing to semifinishing at medium to high cutting speeds and feeds.
