DCMT070208-MM4 WSM20S – Rhombic 55° turning insert, Tiger·tec Silver (Walter Tools)

The DCMT070208-MM4 WSM20S is a coated rhombic 55° turning insert designed for demanding machining of stainless steel and heat-resistant alloys, offering consistent edge stability in heavy or interrupted cuts.

• Tiger·tec Silver coating for long tool life
• WSM20S grade for stainless steel and superalloys
• MM4 chipbreaker for controlled chip formation
• Rhombic 55° geometry for versatile turning

Increase productivity through a durable coating and robust grade

The combination of the Tiger·tec Silver technology and the WSM20S carbide grade provides a measurable improvement in wear resistance and process consistency. As a coated carbide insert, it resists thermal softening and maintains a sharp cutting edge under increased temperatures commonly encountered when machining stainless steel or nickel‑based alloys. This translates into longer intervals between tool changes and fewer rejects, supporting a smoother production flow and lower overall machining cost per component.

Secure chip control and stable cutting for difficult materials

Built around the MM4 chipbreaker, the insert promotes predictable chip control, reducing the risk of built-up edge and uncontrolled swarf. For materials classified under ISO groups M and S, this geometry helps evacuate chips efficiently and protects the cutting edge from thermal and mechanical overload. In practical terms, machinists benefit from fewer interruptions for chip clearing and more reproducible surface quality when processing stainless steel and heat‑resistant superalloys.

Geometry and tolerances that support consistent part quality

The rhombic 55° shape with a 0.8 mm corner radius and 7° clearance provides a reliable compromise between strength and finish; the radius supports edge robustness while the relief angle reduces rubbing and heat generation. The insert’s tolerance class M ensures repeatable mounting and dimensional stability in the toolholder, promoting consistent workpiece accuracy across batches. Use of this insert in appropriate tool assemblies yields repeatable results and supports higher first‑pass yields.

FAQ

What materials is this insert suited for?
The DCMT070208-MM4 WSM20S insert is suitable for stainless steel and heat‑resistant superalloys, with the WSM20S grade optimised for secure chip formation and edge stability in these groups.

How does the MM4 chipbreaker improve machining?
The MM4 chipbreaker on this insert controls chip form and evacuation, reducing built‑up edge and improving surface finish when machining stainless steel and similar difficult materials.

What does the Tiger·tec Silver series provide?
Tiger·tec Silver offers enhanced thermal resistance and wear protection; the coating on the insert increases tool life and helps maintain cutting performance under elevated temperatures.

Is the insert compatible with standard toolholders for DCMT geometry?
The insert follows standard DCMT geometry dimensions (rhombic 55°), enabling use in compatible toolholders designed for this insert type; ensure correct seat and clamping for repeatable results.

What role does the 0.8 mm corner radius play?
A 0.8 mm corner radius balances edge strength and surface finish, supporting interrupted cuts and extending edge life without significantly compromising dimensional tolerance.
