TNMU160508R-G57 WSP45G triangular milling insert — Walter Tools, Tiger·tec Gold, 60° geometry

A TNMU160508R-G57 WSP45G indexable milling insert engineered for versatile milling of Stahl, rostfreier Stahl and heat‑resistant superalloys in demanding production environments

• Tiger·tec Gold PVD coating
• For Stahl, rostfreier Stahl and superalloys
• Triangle 60° geometry
• G57 chipbreaker for stable chip control

Maximised process reliability and extended edge life

The Tiger·tec Gold PVD-coated carbide grade delivers a balance of toughness and wear resistance tailored for milling. With the WSP45G grade, the combination of coating technology and substrate increases resistance to abrasive wear and thermal stress, resulting in fewer tool changes and more productive cutting time. The negative 0° rake geometry contributes to a robust cutting edge under interrupted cuts, while the G57 chipbreaker promotes consistent chip formation. These measurable improvements translate into foreseeable cycle times and reproducible component quality for series production.

Consistent performance across difficult materials

Designed for the ISO groups P, M and S, this insert is suitable for machining unalloyed and alloyed Stahl, rostfreier Stahl and high‑temperature alloys including titanium and nickel‑based superalloys. The triangular 60° form and 0.8 corner radius provide a predictable interaction between tool and workpiece, enabling stable feeds and improved surface integrity. The grade’s toughness helps prevent build‑up on the cutting edge when machining sticky or work‑hardening materials, which supports process security and reduces scrap rates in mixed‑batch production.

Practical geometry and chip control for efficient milling

The compact dimensions and the design for negative rake applications make the insert a strong choice for general face and shoulder milling where robustness is required. The 0.8 corner radius offers a compromise between strength and edge definition, while the G57 chipbreaker reduces the risk of long, stringy chips and supports safe, repeatable toolpaths. Installation and indexing are straightforward thanks to the standardised designation, enabling quick tool changes and shorter downtime between operations — a clear operational benefit for busy workshops.

FAQ

What materials is this insert intended for?
The TNMU160508R-G57 WSP45G insert from Walter Tools is intended for machining Stahl, rostfreier Stahl and heat‑resistant superalloys (ISO groups P, M, S).

How does the Tiger·tec Gold technology benefit milling operations?
Tiger·tec Gold PVD coating on the WSP45G grade increases wear resistance and thermal stability, which in turn extends edge life and enhances process reliability for Walter Tools inserts.

Which chip behaviour can be expected with the G57 breaker?
The G57 chipbreaker is designed to produce controllable chips and stable chip formation, reducing the occurrence of long, tangled chips during milling with this triangular insert.

Is the insert suitable for interrupted cuts and roughing?
Yes; the negative 0° rake and the 0.8 corner radius provide a robust cutting edge that performs well under interrupted cuts and moderate roughing conditions with the TNMU160508R-G57 WSP45G.

How does the triangular 60° shape affect tool selection?
A 60° triangle offers multiple cutting edges and good versatility for face and shoulder milling; the geometry supports efficient edge indexing and predictable cutting behaviour for Walter Tools inserts.
