P4841P-7R-F57 WKP35S — Drilling/boring indexable insert, Tiger·tec Silver (Walter Tools)

The P4841P-7R-F57 WKP35S is a drilling/boring indexable insert engineered for reliable, repeatable machining of steel and cast iron in demanding production settings

• Tiger·tec Silver coating, enhanced tool life
• Optimised 7R-F57 chipbreaker, stable chips
• Suitable for steel (P) and cast iron (K)
• Designed for productive, repeatable cutting

Greater uptime through advanced coating technology

The Tiger·tec Silver technology combines a coated cemented carbide substrate with a high-performance surface layer that reduces abrasive wear and helps maintain a sharp cutting edge. For production environments this translates into longer tool life and fewer index changes, which reduces machine downtime and lowers process costs. Coated carbide is a standard industrial solution where a thin, engineered layer protects the carbide core from heat and friction while preserving cutting-edge stability.

Predictable chip control and improved surface finish

The 7R-F57 chipbreaker geometry is designed to shape and evacuate chips reliably when machining steel and cast iron, reducing the risk of tangling or recutting. Stable chip formation reduces vibration and supports a consistent cut, which in turn improves surface quality and dimensional repeatability. The chipbreaker’s function is to break the swarf into manageable segments; this is particularly valuable in mixed-material batches where chip behaviour otherwise varies significantly.

Robust grade for consistent production results

The WKP35S grade provides a balanced performance aimed at industrial turning and boring operations: wear resistance for longer runs and toughness to handle intermittent cuts. Classified for the ISO groups P (steel) and K (cast iron), this grade is suitable where reliable, repeatable cutting performance is required across typical workshop materials. Integration into existing toolholders is straightforward, enabling productive processes without complex adaptation.
