DNMG150408-MM5 WSM20S turning indexable insert, Tiger·tec Silver (rostfreier Stahl & superalloys) — Walter Tools

A DNMG150408‑MM5 WSM20S turning insert engineered for secure, repeatable machining of rostfreier Stahl and heat‑resistant superalloys with a coated carbide grade designed for high thermal and mechanical loads

• Tiger·tec Silver coated carbide grade WSM20S
• Optimised for rostfreier Stahl and superalloys
• Rhombic 55° insert with 0.8 mm corner radius
• Negative rake geometry with MM5 chipbreaker

Consistent process security for demanding alloys

The combination of the Tiger·tec Silver coating and the WSM20S grade produces a tool substrate that resists thermal and mechanical wear, delivering measurable improvements in process security when turning tough materials such as rostfreier Stahl and high‑temperature alloys. Coating technology reduces flank wear and supports stable cutting‑edge performance, which in practice means fewer tool changes and a smoother production flow. This rational advantage translates into higher machine uptime and more predictable component quality.

Predictable chip control and improved surface quality

Equipped with the MM5 chipbreaker and a negative rake design, the insert promotes controlled chip formation and evacuation, reducing the risk of built‑up edge and erratic chips that can damage both component and tool. Controlled chips contribute directly to a superior surface finish and safer machining in interrupted or continuous cuts. For operations where consistent component geometry and finish are essential, the chip management features offer a clear performance benefit that supports efficient downstream processes.

Geometry optimised for turning versatility

The rhombic 55° form with a 0.8 mm corner radius balances versatility and strength: the angle allows for a range of approach angles and turning operations, while the modest corner radius supports edge robustness without sacrificing detail on smaller profiles. As an indexable insert, the component is straightforward to mount and index, enabling rapid replacement and predictable tolerance control under standard clamping systems. The design therefore suits mixed‑batch production where flexibility and repeatability are both required.

Practical advantages for production planning

Tolerance class M and the coded thickness and size make the insert straightforward to specify in procurement and tooling lists; the coated grade is particularly suited to applications where heat generation and adhesion risks are high. Selection of cutting speeds and feeds should reflect the workpiece material group (M and S according to ISO), but the core benefit remains: enhanced tool life and constant results across runs. For shops seeking to standardise on reliable turning solutions, this insert offers an efficient, production‑oriented option.

FAQ

Which materials can be machined with this insert?
The DNMG150408‑MM5 WSM20S insert is designed for rostfreier Stahl (ISO group M) and heat‑resistant superalloys (ISO group S), offering reliable performance where heat and adhesion are common challenges.

What benefits does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating on the WSM20S grade increases thermal resistance and reduces flank wear, helping the insert maintain a stable cutting edge and longer service life under demanding cutting conditions.

How does the MM5 chipbreaker influence machining?
The MM5 chipbreaker promotes consistent chip formation and evacuation, which improves chip control and contributes to a better surface finish while lowering the risk of built‑up edge.

What does the negative rake geometry mean in practice?
A negative rake angle enhances edge strength and is advantageous in heavy‑duty or interrupted cuts, providing a robust cutting edge that tolerates higher mechanical loads without premature chipping.

Is the corner radius suitable for profile accuracy?
The 0.8 mm corner radius represents a compromise between edge strength and profile detail, enabling good repeatability while still allowing reasonably fine turning features.
