DCGT11T302-MM4 WSM20S turning indexable insert by Walter Tools — Tiger·tec Silver, MM4 chipbreaker

The DCGT11T302-MM4 WSM20S is a rhombic 55° turning insert designed for demanding operations in stainless steel and high-temperature alloys.

• Tiger·tec Silver coated carbide for longer life
• Grade WSM20S optimised for tough alloys
• MM4 chipbreaker for controlled chip formation
• Rhombus 55° geometry for versatile turning

Precision coating for consistent production results

The combination of the Tiger·tec Silver coating and the WSM20S carbide grade delivers a balance of wear resistance and edge security that supports stable chip formation in difficult-to-cut materials. The advanced coating reduces flank wear and helps maintain cutting-edge integrity during interrupted cuts and heavy engagement. For production environments where downtime and rework are costly, this insert contributes to process stability and predictable tool change intervals.

Controlled chips and surface quality through geometry and edge design

The MM4 chipbreaker and a 0.2 mm corner radius work together to moderate chip flow and minimise built-up edge, which is particularly beneficial when machining stainless steel or Inconel-type alloys. The rhombic 55° shape and a 7° clearance angle provide an effective balance between strength and accessibility, producing improved surface finishes and reducing the need for secondary operations. This geometry helps sustain cutting pressures within safe limits and supports repeatable component quality.

Flexible integration with standard turning toolholders

With an insert size of 11 and thickness T3, the design is suitable for a wide range of conventional turning toolholders and makes retrofitting into existing toolsets straightforward. The coated carbide substrate and the MM4 chip control make the solution a practical choice for batch production or mixed-series machining where stainless steel is a frequent workpiece material. For precise cutting parameters or application-specific recommendations, Metav Werkzeuge provides cutting data and support to align machining conditions with component tolerances and cycle-time goals.
