SPKT1204AZN WKP35S indexable milling insert — square 90°, 11° clearance — Walter Tools

SPKT1204AZN WKP35S is an indexable milling insert engineered for efficient face and shoulder milling of Stahl and cast iron, utilising the Tiger‑tec Silver coating technology for extended tool life.

Tiger‑tec Silver coating for high wear resistance
WKP35S grade for Stahl and cast iron
Square 90° form for stable milling
11° clearance for controlled cutting geometry

Consistent productivity through optimised grade and coating

The insert combines the WKP35S carbide grade with the Tiger‑tec Silver coating to deliver a dependable cutting edge in mixed production environments. This combination targets the common challenges when machining Stahl and cast iron: abrasive wear, short chip breaks and fluctuating process loads. As a result, the tool offers predictable tool life and reduced frequency of index changes, which supports continuous operation and improves overall throughput. The technical design focuses on repeatable performance rather than single-shot high-speed results, making it suitable for job shops and serial production alike.

Geometry that stabilises machining and improves surface finish

A square 90° form with an 11° clearance provides a robust cutting profile that resists chatter and deflection during shoulder and face milling operations. The insert thickness and rake geometry create a solid contact area in the pocket, improving clamping stability and reducing micro‑vibration. These characteristics translate into a more consistent surface finish and fewer rework cycles. For users working across a range of component sizes, the geometry helps to maintain dimensional accuracy while allowing the selection of conservative cutting parameters where required.

Application guidance and integration into the toolroom

Designed for straightforward integration into standard milling holders that accept SPKT inserts, this insert is suitable for medium to heavy interrupted cuts commonly encountered with cast components and alloyed Stahl parts. The code corresponds to a modular system that facilitates quick indexing and minimal set‑up time. For best results, match the holder and clamping system to the insert’s 90° form and verify seat condition before clamping to ensure the WKP35S grade performs as intended. For further machining parameters and holder recommendations, Metav Werkzeuge’s technical advisers can provide tailored data for specific machines and materials.

FAQ

What materials is this insert suited for?
The SPKT1204AZN WKP35S insert is formulated for machining Stahl and cast iron, utilising the WKP35S grade and Tiger‑tec Silver coating to handle abrasive wear and typical chip behaviour.

Which insert geometry does it feature and why does that matter?
The insert has a square 90° form with an 11° clearance; this geometry provides stable support in the cutter head and helps to maintain surface quality during face and shoulder milling.

Is this insert compatible with standard SPKT toolholders?
Yes, the designation SPKT1204AZN indicates the insert family and is compatible with toolholders designed for SPKT‑type indexable milling inserts; ensure the pocket and clamp type match the insert form.

How does the Tiger‑tec Silver coating benefit production?
Tiger‑tec Silver enhances wear resistance and edge robustness, which leads to longer intervals between index changes and more consistent machining results in serial production.
