TNMU160508R-G27 WSP45G milling insert — Tiger·tec Gold, triangle 60° (Walter Tools)

TNMU160508R-G27 WSP45G is a coated-carbide milling insert designed for versatile milling operations, delivering stable cutting performance across steel, stainless steel and heat‑resistant alloys.

• Tiger·tec Gold coated grade WSP45G
• Suitable for steel, stainless steel, superalloys
• Negative rake 0° for stable cutting
• Triangle 60° form, 0.8 mm nose radius

Predictable chip control for continuous production

The combination of the G27 chipbreaker and the Tiger·tec Gold coating provides consistent chip formation and evacuation under varying cutting conditions. The insert’s triangle 60° form and 0.8 mm radius generate a robust cutting edge that resists chipping during interrupted cuts and heavy engagement. With a 0° negative rake, the geometry shifts loading away from the cutting lip, which improves edge stability and reduces the risk of built‑up edge during machining of tougher materials. This results in fewer unplanned tool changes and a steadier production flow, which is critical for medium‑volume manufacturing.

Broad material capability reduces tool inventory

Designed for application across the ISO groups P (steel), M (stainless steel) and S (heat‑resistant alloys / titanium), the WSP45G grade enables one insert type to cover multiple workpiece materials. The coated, PVD‑based composition offers a balance between toughness and wear resistance, making it suitable for both roughing and semi‑finishing passes. Using a single, versatile grade helps lower overall tooling complexity and inventory costs while keeping machining set‑ups simpler and repeatable. The insert’s tolerance class M supports consistent seating and repeatable positioning in standard clamping systems.

Durable coating and geometry for improved component quality

The Tiger·tec Gold coating technology enhances thermal stability and reduces flank wear, supporting longer tool life and improved surface finish on machined components. The insert thickness code and the triangular form provide multiple indexed cutting edges per insert, contributing to economical usage and predictable performance. For operations requiring a stable edge under elevated temperatures—such as machining austenitic stainless steels or nickel‑base alloys—the coated grade and negative‑rake geometry help to maintain a reliable cutting edge and a consistent surface appearance on the workpiece.

FAQ

What materials is this insert suitable for?
The TNMU160508R-G27 WSP45G insert is specified for ISO groups P, M and S — that is, steel, stainless steel and heat‑resistant superalloys or titanium — thanks to its WSP45G PVD grade and robust geometry.

What benefits does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating increases thermal resistance and wear performance, helping the insert maintain a sharp edge longer and improving workpiece surface quality during sustained milling.

How does the 0° negative rake affect cutting?
A 0° negative rake increases edge strength and reduces micro‑chipping risk under heavy loads or interrupted cuts, delivering greater cutting‑edge stability compared with positive‑rake geometries.

Which machining tasks suit this triangular insert best?
The insert’s triangle shape and 0.8 mm radius are well matched to face milling, shoulder milling and general slotting where a balance of edge strength and acceptable surface finish is required.
