XNHF0705ANN-D27 WKK25G milling insert – Tiger·tec Gold, for cast iron | Walter Tools

XNHF0705ANN-D27 WKK25G is a negative‑rake milling insert designed for productive cast iron machining

• Tiger·tec Gold coating for high wear resistance
• Optimised for cast iron (ISO group K)
• 0° negative clearance for robust cutting
• D27 chipbreaker for reliable chip control

Longer tool life through optimised coating and geometry

The Tiger·tec Gold coating in this indexable insert provides high wear resistance and thermal stability, which translates into extended, predictable tool life in abrasive cast iron machining. The combination of a coated carbide substrate and a negative‑rake geometry ensures resistance to edge chipping and micro‑fracture under interrupted cuts. The design is particularly suitable for operations where stable performance and reduced tool change frequency contribute directly to lower cycle times and improved process efficiency.

Stable chip control and consistent surface results

With the integrated D27 chipbreaker, the insert produces short, controllable chips typical for grey and nodular cast irons, reducing chip entanglement and improving evacuation in high‑feed milling. Controlled chip formation supports a more consistent cutting force and therefore a steadier surface finish, even in cyclic or interrupted cuts. The insert’s geometry is tailored to handle the brittle chip behaviour of cast iron, enabling reliable results without complex parameter adjustments.

Practical integration, dimensional clarity and repeatable accuracy

Manufactured to tolerance class H, the insert in size 07 with a thickness of 05 fits standard milling toolholders and clamping systems, ensuring repeatable seating and minimal setup variation. The 0° negative clearance and execution designation F deliver a robust cutting edge for heavy engagement, while the coated carbide substrate offers thermal and mechanical resilience. Technical data such as chipbreaker D27 and the WKK25G grade facilitate straightforward selection for cast iron applications under ISO 513 categorisation.

FAQ

What materials is this insert intended for?
The XNHF0705ANN-D27 WKK25G milling insert from Walter Tools is optimised for cast iron (ISO group K) and designed to handle the abrasive and fragmenting chip behaviour typical of those materials.

How does the Tiger·tec Gold coating benefit production?
Tiger·tec Gold on the WKK25G grade increases wear resistance and thermal stability, which helps to extend cutting edge life and maintain process stability during extended milling cycles.

What chip control can be expected with the D27 chipbreaker?
The D27 chipbreaker on this insert promotes short, controlled chips in cast iron milling, improving chip evacuation and reducing the risk of re-cutting or entanglement.

Is the insert suitable for heavy interrupted cuts?
Yes, the 0° negative clearance and robust coated carbide substrate make the insert resistant to edge chipping and suitable for heavier engagements typical of interrupted milling in cast iron.
