Ceramic Inserts optimize high-temperature alloy machining.
Press Release Summary:
Featuring self-reinforced structure of silicon nitride ceramics and optimized chemical stability, WIS10 Grade offers notch wear resistance and excels at machining all types of heat-resistant high temperature alloys such as Inconel, Waspalloy, and Stellite. WWS20 Grade, featuring Whisker fibers, offers fracture and crack resistance and is suitable for nickel-based alloys and difficult conditions, such as machining forged out-of-round workpieces with uneven surfaces.

Walter USA, LLC New Ceramic Inserts Optimize High-Temp Alloy Machining
New grades make machining faster and more economical.
Waukesha, WI – Walter USA, LLC has introduced a new series of ceramic inserts directed at machining high-temp alloys such as Inconel, Waspalloy and Stellite to name a few. The new inserts feature grades WIS10 and WWS20.
Super alloys, because of the high cutting temperatures generated with greater tool stresses and increased tool wear, can be very tough on carbide tools typically used to machine them. Ceramics, though, because of their extreme hardness, heat resistance and wear resistance, can stand up to these demanding applications.
Walter’s two new complimentary grades, silicon nitride-based WIS10 (Sialon ceramic) and WWS20 with Whisker silicon carbides (Whisker ceramic), do more than simply stand up to these applications with increased tool life and process reliability, they also deliver cutting speeds five to ten times higher than carbide in roughing and semi-finishing operations.
With its self-reinforced structure of silicon nitride ceramics and enhanced chemical stability, WIS10 offers excellent notch wear resistance and excels at machining all types of heat resistant high temp alloys. WWS20 offers superior fracture and crack resistance thanks to its “Whisker fibers,” and is ideal for nickel-based alloys and difficult conditions, such as machining forged out-of-round workpieces with uneven surfaces. It also excels at hard machining of steel.
Walter supplies ceramic inserts in diamond, round and square shapes (CN, DN, RC, RP, RN and SN formats), with different cutting edge designs for turning and milling. In addition, Walter supplies toolholders with carbide shoe and clamping system. This gives the user the best possible toolholder systems for turning with the new ceramic indexable inserts.
The demand for high temperature super alloy parts is constantly increasing, with particularly significant growth recently in the aerospace, energy, petrochemical and medical industries. These industries require components that are highly corrosion-resistant and/or resistant to high temperatures.
Walter USA, LLC offers an extensive line up of cutting tools for milling, drilling, turning, boring and specialized tooling for unique applications through its competence brands Walter Valenite, Walter Titex and Walter Prototyp. As well as multi-level service programs through its Walter Multiply brand. Headquartered in Waukesha, Wisconsin the company has a strong network of distributors and field engineers across North America. The Walter name is synonymous with productivity, thanks to more than 80 years of developing cutting tools and inserts that set new standards in production. Walter USA, LLC combines over 75 years of U.S.-based tooling production with long-standing traditions of quality and innovation.
