TNMU11T304R-G27 WPP35G — milling indexable insert for steel — Walter Tools

TNMU11T304R-G27 WPP35G is a coated triangular milling insert designed for efficient machining of steels, combining Walter Tools' Tiger·tec Gold grade with a performance-oriented chipformer.

• Tiger·tec Gold coating for improved wear
• Optimised G27 chipbreaker for steel
• Triangle 60° insert, 11 mm inscribed circle
• 0.4 mm corner radius, 0° negative geometry

Stable performance for steel milling and predictable tool life

The WPP35G grade, part of the Tiger·tec Gold series, is a coated cemented carbide developed for the thermal and chip-forming conditions typical of steel machining (ISO group P). Its coating and substrate balance offers improved wear resistance and stable chip formation, which leads to more predictable tool life and fewer unscheduled tool changes. The result is improved uptime and a consistent surface finish on workpieces made from a wide range of steels, from unalloyed to alloyed grades.

Compact triangular geometry for secure clamping and reproducible results

A 60° triangular form with an 11 mm inscribed circle and T3 plate thickness provides a compact but stable seating in the cutter body. The 0.4 mm corner radius combines edge strength with acceptable edge roundness for finishing applications, while the 0° negative rake contributes to robust cutting-edge behaviour under interrupted cuts. These geometry choices reduce vibration and help maintain repeatable outcomes across batches, supporting tight tolerance production and surface-quality requirements.

Chip control and process reliability for higher productivity

The integrated G27 chipbreaker is optimised for steel: it breaks and evacuates chips reliably under typical cutting conditions for this material group, reducing recutting and heat concentration at the cutting edge. The insert’s tolerance class M ensures consistent fit in standard toolholders, which, together with the Tiger·tec Gold coating, supports process security and fewer regrinds. For production environments where shift-to-shift consistency matters, this combination contributes to predictable tool-change intervals and stable cycle times.

Practical selection and application guidance

The insert is supplied in the Walter Tools Tiger·tec Gold family and is intended for machining steels (ISO P). For component-specific optimisation, select cutting speeds and feeds that reflect the workpiece steel grade, depth of cut and machine rigidity; use the G27 chipformer for general-purpose milling in mixed production batches. For advice on matching the insert with cutter bodies and fixtures, Metav Werkzeuge can supply data sheets and recommended parameter sets to help integrate the insert into existing machining processes.

FAQ

What materials is the insert suited for?
The TNMU11T304R-G27 WPP35G insert is designed primarily for steel (ISO P) applications and performs well across unalloyed and alloyed steel grades.

How does the G27 chipbreaker affect machining?
The G27 chipbreaker provides controlled chip segmentation and evacuation when machining steel, reducing recutting and improving surface quality with the WPP35G grade.

What does the 0° negative free angle mean in practice?
A 0° negative free angle increases edge strength and makes the insert more tolerant of heavy or interrupted cuts, enhancing reliability in demanding milling operations.

Which cutter body and clamping should be used with this insert?
Use a compatible triangular-pocket milling body sized for an 11 mm inscribed circle and a T3 plate thickness; ensure correct seating to maintain the insert’s M tolerance-class positioning.
