Walter has introduced Tiger•tec® Silver HU6, a round insert with a new geometry, specifically developed for medium and heavy-duty roughing of solid railroad wheels and other forged parts. Large chip build-up is a common problem particularly when turning the inner profile of a railroad wheel, with the chips often failing to break as desired. Productivity and tool life both suffer as a result. Tiger•tec Silver HU6 was developed to address these chip control problems, and field tests at wheel manufacturers have shown that this new Walter insert provides up to 40 percent longer tool life.

The key innovation is the insert’s geometry, featuring specially formed chip dimples for ideal chip formation, facilitating chip breaking in the required area. This new round insert benefits from Walter’s proven Tiger•tec Silver coating which enhances cutting speed, reliability and tool life. The inserts are available in four different grades: three for steel and one for cast iron machining. Insert diameter selection ranges from 10 to 32 mm. This combination of coating and geometry, with its specially designed chip breaker and strong cutting edge for process reliability in heavy and interrupted cuts, boosts the productivity of heavy-duty roughing operations, such as railway vehicle manufacturing, generator and turbine manufacturing, and forged components in general. In addition, Walter Capto™ turning toolholders can be used with the HU6. This interface enables quick tool changes and easily handles the transfer of large forces.

Walter 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 their subsidiaries in the USA, Canada, Mexico, Brazil and Argentina. The Walter name is synonymous with productivity, thanks to more than 90 years of developing cutting tools and inserts that set new standards in quality, innovation and production.
