Walter has introduced Tiger·tec Silver HU6, a round insert with a 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 chipbreaking in the required area. This round insert benefits from Walter’s Tiger·tec Silver coating, which is designed to enhance 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 chipbreaker and strong cutting edge for process reliability in heavy and interrupted cuts, boosts the productivity of heavy-duty roughing operations.
