Applications
This turning insert excels particularly in medium metal removal and precision finishing operations on components made of standard steel and stainless steel. The triangular geometry and specific HF chipformer create excellent conditions for accurate contour turning in daily industrial applications. Because the tool operates reliably even under light interrupted cutting conditions, it provides flexible usage possibilities across both single-part prototyping and volume production setups.
Special features
The combination of a robust P10-P30 and M10-M30 carbide substrate with a wear-resistant PVD multilayer coating supports sustained and predictable cutting performance. This advanced coating technology minimizes premature edge wear and promotes a consistently high surface finish on the workpiece. The positive inserts are supplied in a convenient packaging unit of 10 pieces, facilitating practical tool inventory management for professional machining environments.
