TNMG160408-RM5 WSM20S — Turning insert (Triangle 60°) by Walter Tools, for stainless steels and superalloys

The TNMG160408-RM5 WSM20S is a triangular indexable insert designed for turning operations in rostfreie Stähle and heat-resistant superalloys, combining a robust coating and a chipforming geometry that supports secure cutting under high thermal load.

• Tiger·tec Silver coating for high wear resistance
• Optimised for stainless steel and superalloys
• Triangle 60° insert with 0.8 mm corner radius
• Negative 0° rake for stable cutting

Higher metal removal rates for difficult-to-machine alloys

The combination of the WSM20S grade and the Tiger·tec Silver coating is engineered to improve thermal stability and edge strength when machining stainless steels and nickel- or cobalt-based alloys. The advanced coated carbide substrate resists abrasion and reduces microchipping at the cutting edge, which in turn enables higher cutting speeds and extended tool life. For workshops seeking predictable cycle times, this translates into improved throughput and fewer tool changes, delivering tangible gains in process efficiency and machine utilisation.

Reliable chip control and consistent surface finish

The integrated RM5 chipbreaker and the triangular 60° geometry support controlled chip formation and evacuation, even under the low-thermal-conductivity conditions typical of superalloys. The 0.8 mm corner radius offers a balance between edge strength and finish capability, helping to avoid built-up edge and maintain a consistent surface quality. The 0° (negative) rake angle increases cutting-edge robustness for interrupted cuts and long overhangs, reducing the risk of edge degradation during demanding turning cycles.

Robust specification for secure integration into production

Tolerance class M and the proven design cues of the Tiger·tec Silver series ensure the insert fits established toolholders and clamping systems with minimal adjustment. The marked geometry and thickness code assist in fast tool setup and repeatable results across batches. When mounted in a suitable turning holder, the insert supports steady, repeatable performance that contributes to process stability and predictable maintenance intervals — an important factor for production planning and cost control. The Walter Tools pedigree underpins this consistent behaviour with a focus on cutting-edge durability.

FAQ

What materials is this insert suited for?
The TNMG160408-RM5 WSM20S insert is designed for rostfreie Stähle and heat‑resistant superalloys (ISO groups M and S), offering wear resistance and thermal stability for these demanding materials.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker provides controlled chip formation and evacuation; with the Tiger·tec Silver coating and 0.8 mm corner radius, the insert supports improved surface finish and reduced edge wear during continuous turning.

Which geometry fits standard toolholders?
The triangular 60° form and the TNMG designation make the insert compatible with common indexable turning holders designed for TNMG‑type inserts, enabling quick replacement and repeatable positioning.

Is the negative rake suitable for interrupted cuts?
Yes, the 0° negative rake increases edge robustness and is well suited to interrupted cuts or applications with extended tool overhang where edge stability is critical.

How does the WSM20S grade differ from general-purpose grades?
WSM20S is a Walter Tools coated carbide grade within the Tiger·tec Silver family, optimised for high temperature resistance and stable cutting in rostfreie Stähle and superalloys, offering longer tool life under thermal load.
