Increased productivity through a wear‑resistant grade

The coated carbide WKP25S grade, part of the Tiger‑tec Silver series, offers a clear performance advantage when machining Stahl and cast iron. Designed to tolerate the higher thermal loads and typical chip formation of these materials, the grade provides improved tool life and consistent cutting performance. By combining the coating technology with a geometry tuned for robust engagement, the insert reduces flank and crater wear, which translates into fewer tool changes and higher machine uptime. The result is a measurable gain in productivity and process economy for both finishing and semi‑roughing operations.

Reliable chip control and stable cutting geometry

The square 90° form with a 1.2 mm corner radius and the F57 chipbreaker create predictable chip shapes and evacuation, especially in interrupted or variable cuts. The 0° (negative) relief angle increases edge strength and resists edge chipping under higher feed rates. In practice, this means the insert maintains dimensional stability on demanding passes and improves surface integrity on the workpiece. The chipbreaker geometry is optimised to break and guide swarf away from the cutting zone, reducing recutting and the risk of built‑up edge—advantages that directly affect cycle times and part quality.

Consistent part quality with industrial robustness

Tolerance class M and the Tiger‑tec Silver production standards ensure repeatable performance across batches. The combination of the coated carbide substrate and the engineered chipbreaker supports repeatable surface finishes and reliable process security across production runs. For manufacturing environments that demand predictable tool life and steady results, this insert is suited to catalogue‑ and geometry‑dependent applications in both steel and cast iron ISO groups. The robust execution and Walter Tools system compatibility provide an industrially proven choice for shops seeking dependable milling solutions.

FAQ

Which materials is this insert suitable for? The SNMX120512-F57 WKP25S insert is designed for machining Stahl (ISO group P) and cast iron (ISO group K) as indicated by the WKP25S grade and Tiger‑tec Silver series.

What is the purpose of the F57 chipbreaker? The F57 chipbreaker on the SNMX120512-F57 WKP25S promotes controlled chip formation and evacuation, improving surface finish and reducing the chance of recutting in interrupted cuts.

How does the 0° negative relief affect performance? A 0° (negative) relief increases edge strength and stability under heavy or interrupted cutting, which enhances tool life and process reliability for demanding milling tasks.

Can this insert be used for both finishing and roughing? Yes, the combination of the WKP25S grade, robust geometry and 1.2 mm corner radius makes the insert suitable for both finishing and semi‑roughing applications, depending on the specific machining parameters.

What tolerance class does the insert comply with? The insert is supplied to tolerance class M, supporting consistent seating and repeatable performance in standard toolholders.
