Applications
This tool is aimed at turning stainless steel components in both batch and single-part production. The design is an excellent choice for roughing and medium machining tasks that require high material removal rates. Thanks to its robust construction, the carbide insert manages light interrupted cuts while maintaining process stability.
Special features
The advanced PVD coating of the M20-M30 carbide grade protects the cutting edges against premature wear and high thermal loads. The negative basic shape and the 80° geometry of the trigon insert ensure secure clamping in the tool holder. At the same time, the MR chipbreaker allows for dependable chip control at moderate depths of cut. Supplied in a practical 10-piece packaging unit, it is perfectly suited for professional supply management.
