DNMG150608-RM5 WSM20S indexable turning insert – Tiger‑tec Silver, for stainless steels and superalloys (Walter Tools)

The DNMG150608-RM5 WSM20S is an indexable turning insert engineered for reliable machining of stainless steels (M) and heat‑resistant superalloys (S), offering a balance of edge stability and thermal resistance for productive turning operations.

• Tiger‑tec Silver coating for heat resistance
• WSM20S grade for stainless and superalloys
• RM5 chipbreaker for secure chip control
• Rhombic 55° form with 0.8 mm corner radius

Consistent performance under thermal stress

The Tiger‑tec Silver coating and the WSM20S carbide grade combine to deliver improved thermal stability and wear resistance when machining materials that generate high temperatures. Coating technologies like Tiger‑tec Silver reduce flank and crater wear by stabilising the cutting edge at elevated temperatures, which translates into longer tool life and fewer indexings. For process planners, this means more predictable component tolerances and less unplanned downtime, particularly in series production where consistency is critical.

Predictable chip formation and process security

The RM5 chipbreaker geometry promotes controlled chip breaking and evacuation when turning ductile or work‑hardening materials. A well‑matched chipbreaker reduces the risk of entangling chips, improves surface finish potential and supports stable cutting forces during each pass. Combined with the negative 0° relief angle, this geometry reinforces edge strength, making the insert suitable for applications where secure chip control and reliable edge retention are priorities rather than high‑shear finishing alone.

Geometry tailored for strength and versatility

The rhombic 55° insert form with a 0.8 mm corner radius offers a compromise between edge robustness and accessibility in shoulder and light profiling operations. The specified plate size and thickness classification ensure compatibility with standard tool holders for this insert format. Classified for tolerance class M, the design supports repeatable seating and positional accuracy in automatic tool changers. Use of this insert in the correct ISO material groups delivers the best combination of cutting performance and predictable edge life.

Application guidance and material groups explained

This grade is intended for machining ISO group M (stainless steels) and S (heat‑resistant superalloys and titanium) materials. Stainless steels are often tough and prone to built‑up edge; the WSM20S formulation supports safe chip formation and stable cutting edges to mitigate these effects. Superalloys and titanium transfer heat poorly and demand grades that maintain hardness at temperature—this insert’s coating and carbide substrate are selected to address those demands while helping to secure dimensional accuracy over longer tool cycles.

FAQ

Which materials is this insert suitable for?
The DNMG150608-RM5 WSM20S indexable turning insert from Walter Tools is designed primarily for ISO groups M (stainless steels) and S (heat‑resistant superalloys and titanium), where thermal stability and edge strength are required.

What does the WSM20S designation mean?
WSM20S denotes Walter Tools’ coated carbide grade within the Tiger‑tec Silver family; it represents a formulation optimised for heat resistance and stable cutting performance in tough‑to‑machine materials.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker promotes controlled chip segmentation and efficient evacuation, improving surface integrity and reducing the likelihood of chip interference in bore or shoulder turns.

How do geometry and relief angle influence use?
The rhombic 55° form and 0.8 mm corner radius provide a robust cutting edge for general turning and light profiling, while the 0° negative relief enhances edge strength for interrupted cuts and heavy engagement.

Is this insert suitable for finishing passes?
Depending on toolholder rigidity and cutting parameters, the grade is capable of producing good finishes; however, its strength and thermal focus make it particularly well suited to semi‑finishing and roughing in stainless and superalloy applications.
