XNHF070508-D67 WKP25S milling insert — for steel and cast iron (Walter Tools)

A robust milling insert in the Tiger·tec Silver range designed for productive machining of steel and cast iron, offering a coated-carbide grade optimised for reliable chip control and extended tool life

• Tiger·tec Silver coating for long life
• Optimised for steel and cast iron
• Negative 0° rake for stable cutting
• 0.8 mm corner radius for robust edges

Reliable productivity from the coating and grade

The core advantage of the Tiger·tec Silver series is its coating technology, which enhances thermal stability and reduces abrasive wear during heavy-duty cuts. The WKP25S grade is a coated carbide formulation tailored for the cutting conditions typical of steel and cast iron. This results in more consistent cutting forces, fewer unplanned tool changes and a noticeable improvement in machining uptime. For operations seeking repeatable surface quality and reduced tool consumption, the coating-grade combination supports efficient cycle times and predictable tool life.

Stable geometry for consistent results

Geometry parameters such as the negative 0° rake, the 0.8 mm corner radius and the D67 chipbreaker are engineered to deliver robust performance in interrupted cuts and mixed-operation milling. A negative rake increases edge strength, reducing the risk of chipping under heavy loads, while the rounded corner radius balances edge durability with acceptable surface finish. The D67 chipbreaker promotes short, controlled chip formation in both long and short-chipping scenarios, easing chip evacuation and improving process security on medium- to high-strength materials.

Practical benefits for production workflows

Choosing this insert supports streamlined tool management: the standardised designation and tolerance class H simplify inventory pairing, and the plate size 07 with thickness 05 fits common cutter pockets for flexible tool set-ups. The grade’s suitability for ISO groups P and K (representing steel and cast iron) makes it a versatile option across mixed-production environments. Operators and process engineers benefit from reduced rework, improved surface integrity and fewer tool interventions, which together contribute to lower unit costs and more predictable manufacturing output.

FAQ

What materials is this insert intended for?
The Tiger·tec Silver WKP25S grade is designed for machining steel (ISO P) and cast iron (ISO K), offering balanced wear resistance for both material families.

How does the D67 chipbreaker affect chip formation?
The D67 chipbreaker produces short, controllable chips under typical milling conditions, improving evacuation and reducing the risk of chip-related surface damage when using the XNHF070508-D67 WKP25S insert.

Is the negative 0° rake suitable for interrupted cuts?
Yes, the negative 0° rake increases edge strength and helps prevent chipping during interrupted milling, making the insert suitable for heavy engagement and roughing operations.
