DCMT070204‑MM4 WSM20S turning insert — Tiger‑tec Silver coated, Walter Tools (for stainless steels and superalloys)

The DCMT070204‑MM4 WSM20S is an indexable turning insert designed for heavy cutting and secure chip control in ISO M and ISO S applications, combining a robust coated carbide grade with a dedicated chipbreaker geometry

• Tiger‑tec Silver coating for wear resistance
• Optimised MM4 chipbreaker for stable chips
• 0.4 mm corner radius for fine surface finishes
• Suitable for stainless steels and superalloys

Longer tool life through advanced coating technology

The insert’s Tiger‑tec Silver coating and the WSM20S grade deliver a combination of thermal stability and wear resistance that supports continuous production in challenging environments. As a coated carbide solution, the geometry and surface treatment reduce flank wear and help maintain cutting-edge integrity over longer tool cycles. This translates to fewer insert changes and increased machine uptime, which benefits batch production and one-off jobs alike.

Safer machining with controlled chip formation

The MM4 chipbreaker is engineered to produce short, consistent chips when machining tough, low-thermal-conductivity materials. Stable chip formation minimises the risk of built-up edge and reduces interruptions caused by entangled swarf. The result is smoother tool engagement, improved surface integrity and a lower likelihood of unplanned stoppages, which supports predictable process planning and improved throughput.

Precision geometry for reliable surface quality

A rhombic 55° shape combined with a 0.4 mm corner radius and 7° clearance delivers precise contact geometry for turning operations that demand consistent part finish. The insert form supports repeatable cutting forces and stable tool–workpiece interaction, promoting superior surface quality while limiting vibration. For precision-oriented workshops, this geometry helps achieve target tolerances with fewer rework cycles.

Broad application range and process security

Designed for machining stainless steels (ISO M) and heat‑resistant superalloys or titanium (ISO S), the insert offers process security in demanding material classes that typically cause edge deterioration and thermal loading. Its specification supports part producers and subcontractors working with exotic alloys, where consistent performance and predictable tool life are essential. The insert suits both finishing and medium turning tasks, providing a balance between economy and performance.
