TNMU11T308R-G27 WKP35G Triangular 60° milling indexable insert, Tiger·tec Gold (Walter Tools)

The TNMU11T308R-G27 WKP35G is a triangular 60° milling insert with Tiger·tec Gold coating, engineered for efficient and reliable machining of steel and cast iron.

• Tiger·tec Gold coating for high wear resistance
• Optimised for steel and cast iron machining
• Triangle 60° form with 0.8 mm corner radius
• Negative 0° rake for stable cutting

High productivity for steel and cast iron

The TNMU11T308R-G27 WKP35G insert combines the Tiger·tec Gold coating and the WKP35G cutting grade to extend tool life under typical steel and cast iron cutting conditions. The coating reduces abrasive wear while the grade provides reliable fracture resistance, which together allow for higher cutting parameters and fewer tool changes. P and K designations refer to the ISO material groups: P for various steels and K for cast iron, so the insert is optimised for both material families. The result is a measurable improvement in process efficiency and a lower cost per component when machining moderate to demanding workpieces.

Predictable chip control and stable cutting performance

Built around the G27 chipbreaker and a negative 0° rake, the insert is designed for controlled chip formation and steady cutting forces in interrupted and continuous milling operations. The 0.8 mm corner radius increases edge strength for roughing applications while the triangular 60° form permits three indexed cutting edges per insert, improving tool utilisation. These technical choices minimise vibration and reduce the frequency of unplanned stops, supporting continuous production and a predictable maintenance schedule for tool management.

Easy integration and consistent positioning in production

With the standard triangular geometry and a T3 plate thickness, the insert integrates readily into common toolholders and milling systems, simplifying logistics and reducing setup time. The tolerance class M ensures repeatable seating and alignment, which contributes to consistent workpiece quality across batches. Walter Tools’ engineering focus on stable cutting behaviour and surface finish supports reproducible results, making this insert suitable for workshops and production lines seeking robust, repeatable milling performance.
