Applications
The turning insert demonstrates its strengths particularly in the batch and single-part production of components made from difficult-to-machine materials. It is excellently suited for the roughing of special materials and heat-resistant super alloys.
By focusing on continuous cutting conditions, this execution is a practical choice for machining complex workpiece contours and for high-volume material removal.
Special features
The combination of a tough S10 substrate and the TiAlSiN protective layer opens up flexible application possibilities. The special coating reduces heat-related wear and protects the cutting edge during demanding roughing operations.
