XNHF0906ANN-D57 WKP25S — milling indexable insert with Tiger‑tec Silver coating for steel and cast iron | Walter Tools

A XNHF0906ANN-D57 WKP25S milling indexable insert engineered for heavy-duty and reliable machining of steel (P) and cast iron (K) with a negative 0° rake angle for predictable cutting behaviour

• Tiger‑tec Silver coated for wear resistance
• WKP25S grade for steel and cast iron machining
• Negative 0° rake for stable cutting forces
• Chipbreaker D57 for controlled swarf removal

Higher productivity through advanced coating and grade

The combination of the Tiger‑tec Silver coating with the WKP25S cemented carbide grade delivers a measurable increase in process security and tool life when machining steels and grey or nodular cast irons. The coating reduces abrasive wear and thermal impact on the cutting edge, which translates into fewer tool changes and longer uninterrupted production cycles. For industrial shops aiming to reduce cycle times, this insert offers a reliable balance between edge stability and toughness, making it suitable for both roughing and medium‑finishing operations.

Consistent chip control and dimensional stability

Built around the chipbreaker D57 geometry and a negative 0° rake, the insert secures consistent swarf formation and evacuation under the thermal and mechanical loads typical of steel and cast iron. The stable cutting edge geometry helps to maintain component tolerances and surface finish over longer tool life, reducing rework and inspection overhead. The insert’s tolerance class H supports predictable clamping and repeatable positioning in modular milling holders, which benefits automated production and high‑volume batches.

Seamless integration into production workflows

With an insert size designation of 09 and thickness 06, this indexable plate fits established milling tool systems and supports quick index changes to restore cutting performance. The coated cemented carbide substrate is optimised for industrial machining strategies where consistent results and low variance are essential. Using these inserts in standard milling modules enables a clear calculation of cost per edge and helps to plan maintenance cycles. Technical teams will appreciate the straightforward material classification (P / K) aligning with ISO 513 groups for selecting cutting data.

FAQ

What materials is this insert suitable for?
The XNHF0906ANN-D57 WKP25S insert is specified for ISO groups P (steel) and K (cast iron) and is designed to cope with the thermal and abrasive demands of these materials.

How does the Tiger‑tec Silver coating benefit machining?
The Tiger‑tec Silver coating on the WKP25S grade reduces abrasive wear and improves heat resistance, resulting in longer edge life and fewer tool changes in steel and cast‑iron milling.

What does the negative 0° rake mean in practice?
A negative 0° rake gives a robust cutting edge and stabilises cutting forces, which helps when milling rough or interrupted cuts and supports dimensional consistency during heavy engagement.

Is the chipbreaker D57 suitable for finishing operations?
The D57 chipbreaker is optimised for controlled swarf formation and evacuation; while primarily effective in moderate to heavy cuts, it also supports finishing passes when cutting parameters are adjusted accordingly.

Which toolholders are compatible with this insert size and thickness?
Insert size 09 and thickness 06 conform to common modular milling holders; compatibility should be checked against the specific toolholder catalogue, ensuring correct seat and clamp geometry for the XNHF0906ANN‑D57 plate.
