Kennametal’s New KCS10B turning grade is especially effective with nickel, cobalt and iron-based superalloys used in aerospace and other high-temperature applications. Robert Keilmann, Senior Global Product Manager for Turning, explained that the secret behind the success of KCS10B is Kennametal’s proprietary High-Power Impulse Magnetron Sputtering (High-PIMS) technology. Rather than the light rain of droplets that fall on cutting tools during traditional PVD coating processes, High-PIMS generates a fine mist of AlTiN, building a series of, “extremely thin, smooth, and wear-resistant layers.”

Featuring a long tool life
Superalloys are hard to work with and can present a number of complications. This includes cratering and depth-of-cut notching. Machinists know that these wear modes can cause problems that can derail an entire project by leading to unexpected and catastrophic tool failure.  The new a post-coat treatment reduces friction and allows for a longer tool life. Other benefits of this new technology include:

• Increased productivity.
• Optimum layer adhesion, especially on sharp cutting edges.
• High depth-of-cut notching resistance.
• Improvement of edge toughness.
• Up to 50% greater tool life.

High PIMS coating
Apply the High-PIMS coating to an extremely hard and wear-resistant, ultra-fine grade carbide substrate and you have a turning grade that:

• Reduces depth-of-cut notching.
• Can be used for a wide range of applications.
• Allows for better insert wear detection.

KCS10B is versatile
The KCS10B can be used for several applications. These include:

• Turning
• Boring
• Back Boring
• Profiling
• Facing
• I.D. Facing
• Chamfer Turning
• Deep Grooving
