Consistent productivity and tool life through engineered coating

The Tiger·tec Silver series provides a coated carbide solution engineered to balance wear resistance and thermal stability, translating into longer tool life and fewer insert changes. For operations in Stahl and Gusseisen, the WKP35S grade is optimised to handle the heat and abrasive conditions typical of these material groups, reducing downtime and improving overall process economy. This performance-oriented combination supports stable cutting forces and predictable wear curves.

Geometry and relief that improve chip formation and surface quality

A square 90° plate with an 11° relief angle offers robust support at the cutting edge while maintaining favourable cutting kinematics. The geometry reduces the tendency for built-up edge on interrupted cuts and aids chip breaking in short, brittle chips typical of Gusseisen work. As a result, the machining process benefits from improved surface integrity and fewer rejects, contributing to a more efficient production flow.

Practical advantages for milling operations and fixture planning

The insert’s compact 15 size and thickness code 04 simplify tool selection for common milling cutters, enabling predictable clamping and stability under moderate depths of cut. The standardised indexable format eases inventory management and speeds changeover when combined with compatible cutter bodies. Integration into existing tool systems is straightforward, which supports seamless implementation in both job-shop and production-line environments.

Application guidance and material suitability

WKP35S was developed with a focus on the ISO groups P and K; it is therefore well suited to machining Stahl (unalloyed and alloyed) and Gusseisen where abrasive wear and short, breaking chips are typical. The coated grade accommodates a range of cutting speeds and feeds common in roughing and semi-finishing, offering a balance between productivity and surface finish. Selection of cutting data should follow manufacturer recommendations and be adapted to machine rigidity and workpiece clamping.

Reliability and process security from a proven manufacturer

Walter Tools provides catalogued grades and geometries that aim to deliver repeatable results and consistent tool life. The SPKT1504AZN family benefits from that development focus, offering a reliable option when process stability and predictable performance are priorities. For production-critical operations where reproducibility matters, the combination of grade and coating supports sustained throughput and reduced tool-related interruptions.

FAQ

What materials is this insert best suited for?
The SPKT1504AZN WKP35S is optimised for machining Stahl and Gusseisen, reflecting the P and K ISO material groups for which the WKP35S grade was developed.

How does the Tiger·tec Silver coating benefit milling operations?
Tiger·tec Silver on this insert improves wear resistance and thermal stability, which helps extend tool life and maintain consistent cutting performance in demanding milling applications.

Can this insert be used for finishing passes?
Yes; the insert’s geometry and coated grade allow use in both semi-finishing and finishing operations, provided cutting data are adjusted for the required surface quality and machine rigidity.

How is chip control achieved with the square 90° geometry?
The square 90° form combined with an 11° relief promotes stable cutting forces and facilitates chip breaking, particularly useful for intermittent cuts and the short-chip behaviour of Gusseisen.

Is the SPKT1504AZN WKP35S compatible with standard cutter bodies?
The indexable format follows common plate dimensions and can be used with compatible cutter bodies specified for the SPKT1504 geometry and size.
