TNMU11T304R-G57 WSP45G – Walter Tools triangular milling insert (Tiger‑tec Gold, 60°)

A TNMU11T304R-G57 WSP45G triangular indexable milling insert engineered for high‑performance milling across a wide range of materials, including Stahl, rostfreier Stahl and heat‑resistant alloys.

• Tiger‑tec Gold PVD coating
• Suitable for Stahl and rostfreier Stahl
• Triangle 60° geometry, 0.4 mm corner
• Negative rake 0° for stable cutting

High cutting performance and stable manufacturing results

The combination of the Tiger‑tec Gold coating and the WSP45G grade delivers a balanced mix of wear resistance and toughness, making the insert especially suited to demanding milling tasks. The PVD coating reduces flank wear and improves heat resistance, which in turn increases process reliability and extends productive tool life. For production environments that prioritise consistent part quality and predictable regrind intervals, this triangular carbide insert offers measurable gains in cycle stability and reduced downtime.

Broad material capability with predictable chip control

Designed for versatile use, the grade covers the ISO groups P, M and S — i.e. Stahl, rostfreier Stahl and high‑temperature alloys such as Titan and nickel‑based superalloys. The included G57 chipbreaker supports controlled chip formation under varying cutting conditions, which helps to avoid built‑up edge on tougher steels and improves surface finish on stainless grades. This material flexibility reduces the need for frequent tool changes and simplifies tooling inventories in mixed‑material shops.

Geometry that supports productivity and surface quality

The triangular 60° shape with a 0.4 mm corner radius provides a good balance between edge strength and accessibility in tight toolpaths. The negative rake 0° setting enhances edge robustness under interrupted cuts, while the compact insert size (11 mm) and T3 thickness suit light to medium milling operations where rigidity and compact toolholders are required. These geometric choices reduce the risk of chipping during heavy engagement and help maintain a stable cutting edge for longer runs.

Practical handling and application notes for process integration

As an indexable insert, the part simplifies inventory management and reduces tooling costs per cutting edge when compared with brazed solutions. The coated WSP45G grade is tailored for milling routines that demand both thermal stability and consistent chip control; typical applications include shoulder milling, face milling and light slotting of Stahl and rostfreier Stahl. For best results, match the insert to a holder designed for triangular 60° inserts and monitor edge condition to plan economical index and regrind cycles.

FAQ

What materials is this insert suitable for?
The TNMU11T304R-G57 WSP45G insert is designed for use on Stahl, rostfreier Stahl and heat‑resistant alloys (ISO groups P, M and S), offering reliable chip control across these families.

How does the geometry affect tool life and surface finish?
The triangular 60° form with a 0.4 mm corner radius increases edge strength while allowing access in confined toolpaths; the negative rake improves resistance to chipping, which together prolong usable edge life and support consistent surface quality.

Is the grade coated and what benefits does the coating provide?
Yes — the insert uses the Tiger‑tec Gold PVD coating on the WSP45G grade; this coating enhances thermal resistance and reduces flank wear, improving process security during continuous milling operations.

Which toolholders are compatible with this insert?
The insert fits standard toolholders for triangular 60° indexable inserts; pairing with a rigid holder and appropriate clamping ensures repeatable positioning and stable cutting conditions for the TNMU11T304R-G57‑type insert.
