TNMG160404‑MM5 WSM20S — Turning Insert (Tiger‑tec Silver) by Walter Tools, for stainless steel and superalloys

TNMG160404‑MM5 WSM20S is a triangular 60° turning insert designed for demanding applications in stainless steels and heat‑resistant superalloys, delivering stable chip control and consistent cutting performance.

• Tiger‑tec Silver coating for heat resistance
• Optimised chip control with MM5 breaker
• 60° triangle insert with 0.4 mm corner radius
• Negative 0° clearance for secure cutting edges

Improve machining of stainless and heat‑resistant alloys with reliable coating technology

The Tiger‑tec Silver coating and the WSM20S grade are formulated to cope with the specific demands of stainless steel and superalloys (ISO groups M and S). These materials generate heat and tend to form built‑up edge; the coated carbide substrate combined with the MM5 chipbreaker promotes stable chip formation and reduces the risk of edge failure. As a result, process security increases and downtime for insert changes is reduced, supporting predictable cycle times in serial production.

Geometry that balances strength and edge definition for finish and semi‑roughing

A 60° triangular shape with a 0.4 mm corner radius and negative 0° relief provides a robust cutting edge that tolerates interruption and variable cutting forces. The compact corner radius supports controlled surface finish without sacrificing edge stability under thermal load. The insert size 16 and standard thickness deliver a versatile package for a range of holders and turning operations, enabling efficient transitions between semi‑roughing and finishing passes with minimal tool changeover.

Productivity advantages: longer life, fewer interruptions, consistent results

The combination of a wear‑resistant coating and a stable grade reduces flank wear and maintains dimensional consistency across batches. This leads to lower tooling consumption and fewer machine stoppages for index changes, which improves overall throughput. Walter Tools’ design focus on process stability and a controlled chip flow makes this insert a cost‑effective option where machining reliability and component quality are decisive factors.

FAQ

What materials is this insert best suited for?
The TNMG160404‑MM5 WSM20S insert is optimised for stainless steel (ISO group M) and heat‑resistant superalloys or titanium (ISO group S), where thermal load and tough cutting conditions demand a heat‑resistant grade.

Can this insert be used for both finishing and semi‑roughing?
Yes, the triangular 60° geometry with a 0.4 mm corner radius and the MM5 chipbreaker provide a balance between edge strength and surface quality, making the insert suitable for both semi‑roughing and finishing operations.

How does the Tiger‑tec Silver coating improve performance?
The Tiger‑tec Silver coating increases thermal resistance and reduces adhesive wear, which helps to preserve the cutting edge under high temperatures and extend the usable life of the insert.

Is the TNMG160404‑MM5 WSM20S compatible with standard holders?
The insert follows the TNMG form factor and fits compatible triangular turning toolholders designed for 60° TNMG inserts; verify seat dimensions and clamping style for secure mounting.

What chip control can be expected with the MM5 breaker?
The MM5 chipbreaker is designed to produce short, controllable chips when machining stainless steels and superalloys, reducing the risk of long, entangling chips and improving process reliability.
