• Walter Tools quality and repeatability

Consistent performance in steel and cast iron machining

The Tiger·tec Silver coating combined with the WKP35S cutting grade provides a balance of wear resistance and thermal stability that benefits continuous drilling and bore-enlarging tasks. As a coated carbide indexable insert, this geometry manages the heat and abrasive contact typical for group P (steel) and group K (cast iron) applications. The result is reliable flank wear progression and predictable service intervals, which supports stable cycle times and fewer unscheduled tool changes. The combination of coating and substrate ensures the insert maintains cutting edge integrity under typical production loads.

Optimised chip control for safer, faster cycles

Equipped with the chipbreaker 4R-F57, the insert promotes effective chip control across a range of cutting parameters, reducing the risk of long, tangled chips and helping to protect the workpiece surface. The specific chip geometry reduces cutting forces and vibration, which contributes to improved surface finish and dimensional stability in bore operations. For shops where repeatability and throughput matter, this geometry supports higher feed constancy and fewer interruptions for chip clearing, translating into measurable productivity gains.

Coating and grade that extend tool life and reliability

The combination of a coated carbide substrate and the Tiger·tec Silver technology increases resistance to adhesive and abrasive wear while preserving cutting-edge strength at elevated temperatures. This is particularly advantageous when machining abrasive cast irons or medium-alloy steels where thermal loads and intermittent contact can accelerate wear. The engineered coating also improves repeatability from one insert to the next, helping to standardise setup and inspection intervals and to simplify tooling inventory management.

Practical application and handling recommendations

The insert is intended for drilling and bore-enlarging work in a production environment where consistent performance is required. Use standard clamping torque and verified seat cleanliness to maintain positional accuracy; incorrect seating can compromise the insert life and surface quality. For cutting data, consult toolholder and machine guidelines and consider gradual increases in speed or feed when optimising cycle times. For specific parameter windows related to material grades and machine rigidity, Metav Werkzeuge can provide tailored recommendations to match the WKP35S grade to the application.
