TNMU11T304R-G27 WKP35G milling insert — Triangle 60°, Tiger·tec Gold (Walter Tools)

The TNMU11T304R-G27 WKP35G is a triangular milling insert engineered for high-productivity machining of steel and cast iron, offering robust edge life and reliable chip control in demanding production environments.

• Tiger·tec Gold coating for stable cutting
• WKP35G grade for steel and cast iron
• Triangle 60° form with 0.4 mm corner radius
• Negative 0° free angle for strong edge support

Consistent productivity through advanced grade and coating

The combination of Tiger·tec Gold technology and the WKP35G grade delivers a precisely tuned balance between wear resistance and toughness. Designed for the thermal and mechanical loads typical of milling steel and cast iron, the coating reduces abrasive wear while the substrate maintains a stable cutting edge. This results in fewer insert changes, reduced downtime and a measurable improvement in throughput for series production. The outcome is a cost-effective solution for shops seeking predictable tool life and repeatable results.

Geometry that supports reliable surface quality and tool life

The insert’s triangle 60° form and 0.4 mm corner radius provide a versatile geometry suitable for a broad range of shoulder and slot milling tasks. The negative 0° free angle increases edge support for interrupted cuts and heavy engagement, reducing chipping risk under fluctuating loads. The M tolerance class ensures dimensional consistency in toolholders and fixtures, so setup times stay short and repeatability improves. For practical planning, the T3 thickness offers a balance between rigidity and the number of available cutting edges per insert.

Chip control and process integration for efficient milling

The dedicated G27 chipbreaker is optimised for the typical chip forms produced when machining steel and cast iron, promoting continuous evacuation and stable cutting forces. This leads to lower heat concentration at the cutting edge and improved surface quality on the workpiece. Integration into milling routines is straightforward: select speeds and feeds tuned to the workpiece and toolholder rigidity, and the insert will contribute to higher material removal rates with predictable performance. If more detailed cutting data is required, Metav Werkzeuge can supply application recommendations to align the insert with specific machines and operations.
