TNMU160516R-G27 WSP45G milling indexable insert by Walter Tools — Tiger·tec Gold, triangular 60° with 1.6 mm corner radius

The TNMU160516R-G27 WSP45G is a triangular milling insert designed for stable, high-productivity metalcutting in steel, stainless steel and heat-resistant alloys.

• Tiger·tec Gold coating for extended wear resistance
• For steel, stainless steel and superalloys
• Triangular 60° insert with 1.6 mm corner radius
• 0° negative rake for robust milling

Consistent performance for mixed production runs

The combination of Tiger·tec Gold coating and a coated carbide base delivers reliable wear resistance across a wide variety of alloys. The grade WSP45G is formulated for the thermal and mechanical demands of machining groups P, M and S — that is, unalloyed and alloyed steel, stainless steel and heat-resistant superalloys. This chemistry supports secure chip formation and a stable cutting edge under varying cutting conditions, reducing unplanned stoppages. As a result, component tolerances remain consistent across batch changes and mixed-material programmes, improving overall process predictability.

Robust geometry that supports productive feeds and depths

The triangular 60° shape with a 1.6 mm corner radius and a 0° negative rake is optimised for heavy-duty and general-purpose milling where edge stability is essential. The geometry resists edge chipping during interrupted cuts and shoulder milling, while the corner radius balances strength with accessible cutting edge for semi-finishing operations. The negative rake angle contributes to a more secure engagement with workpieces, enabling deeper cuts and higher feed per tooth where machine rigidity and fixture stability allow. This design choice supports higher metal removal rates and improved cycle-time economics for production-focused workshops.

Easier process set-up and predictable tool life

Using the insert’s designation and variant simplifies tooling decisions: the ISO-style marking indicates the insert form and chipbreaker type, while the WSP45G grade signals a PVD-based, versatile coating technology. The insert’s chipbreaker (G27) and grade compatibility make it straightforward to select cutting parameters that prioritise surface finish or tool life depending on the application. For operators and process engineers, this reduces trial-and-error during set-up and shortens ramp-up time for new jobs. The result is a measurable improvement in machine utilisation and fewer tool changes during longer production runs.

FAQ

What materials is this insert suitable for?
The TNMU160516R-G27 WSP45G insert is suitable for material groups P, M and S — covering steel, stainless steel and heat-resistant superalloys — thanks to its WSP45G PVD-coated carbide formulation.

What does the 0° negative rake mean for machining?
A 0° negative rake gives the insert a stronger cutting edge and helps withstand heavy engagement and interrupted cuts; the geometry of this Walter Tools insert supports more robust milling conditions.

How does the Tiger·tec Gold coating improve performance?
The Tiger·tec Gold coating enhances wear resistance and thermal stability, leading to longer tool life and more consistent surface quality in demanding milling applications.

Which chipbreaker is fitted and what is its benefit?
This insert features the G27 chipbreaker, designed to encourage controlled chip formation across a range of feeds and depths, improving surface finish and reducing the risk of built-up edge.

Is the insert suitable for shoulder milling and ramping operations?
Yes, the triangular 60° form with a 1.6 mm corner radius and a robust negative rake makes the insert well suited to interrupted cuts and shoulder milling where edge strength is critical.
