XNMU0705ANN-F27 WKK25G — milling indexable insert for cast iron by Walter Tools

XNMU0705ANN-F27 WKK25G is a dedicated milling indexable insert designed for efficient machining of cast iron under demanding, production-oriented conditions

• Tiger·tec Gold coating for wear resistance
• Optimised for cast iron machining (ISO K)
• 0° negative rake for stable cutting
• Tolerance class M for consistent seating

Stable performance when cutting cast iron

The WKK25G grade, incorporated in this insert, is formulated specifically for cast iron applications and addresses the abrasive wear and short, brittle chips typical of these materials. The combination of a wear-resistant coating and a robust substrate results in stable chip formation and predictable tool life. By reducing unexpected edge breakdown and maintaining cutting-edge integrity, operators achieve more consistent part quality and fewer tool changes, which supports higher uptime and steady production throughput.

Longer tool life and process reliability from Tiger·tec Gold

The Tiger·tec Gold series provides a multilayered coating system optimised for heat resistance and abrasion protection. In practice, this translates to prolonged cutting performance and improved surface finish on cast iron components. The 0° negative rake geometry enhances mechanical stability at the cutting edge, making the insert well suited to interrupted cuts and demanding feed conditions. These features combine to lower tooling costs per component and contribute to a more economical machining process.

Simple integration into existing toolholders and workflows

Designed with a standard ISO designation and M tolerance, this indexable insert fits common milling toolholders and fixtures without extensive modification. The chipbreaker type F27 is engineered to control fragmented chips typical of grey and nodular cast irons, easing chip evacuation and reducing rework. In production environments where repeatability matters, the consistent seating and predictable wear behaviour of the insert support process control and quality assurance protocols. For application-specific recommendations, technical consultation is available to match insert selection to machining parameters.

FAQ

What materials is this insert intended for?
The XNMU0705ANN-F27 WKK25G insert from Walter Tools is specifically developed for cast iron (ISO K) machining, addressing abrasive wear and brittle chip behaviour.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on the WKK25G grade improves heat and abrasion resistance, which extends tool life and helps maintain consistent component quality in series production.

Is the insert suitable for interrupted cuts?
Yes, the 0° negative rake geometry offers enhanced mechanical stability at the cutting edge, making the insert suitable for interrupted cuts and tough engagement conditions.

What chip control can be expected with the F27 chipbreaker?
The F27 chipbreaker is optimised for fragmented chips commonly produced when machining cast iron, supporting effective chip evacuation and reducing the risk of re-cutting.

How precise is the seating and interchangeability of the insert?
With tolerance class M, the insert provides consistent seating accuracy and interchangeability in standard toolholders, aiding repeatable machining results.
