DPGT11T308-MM4 WSM20S – Indexable turning insert, Tiger·tec Silver (Walter Tools)

The DPGT11T308-MM4 WSM20S is an indexable turning insert designed for secure chip control and edge stability in stainless steel and high-temperature superalloys.

• Tiger·tec Silver for high thermal resistance
• MM4 chipbreaker for stable chip formation
• Rhombic 55° form for flexible turning
• 0.8 mm corner radius for durable cutting edge

Increased process reliability for demanding materials

The combination of the Tiger·tec Silver coating and the WSM20S grade targets the particular challenges of machining stainless steel and heat-resistant alloys. The multilayer coating improves thermal resistance and reduces adhesion at the cutting edge, resulting in measurable edge stability and extended tool life under high temperatures. For production environments where control of wear mechanisms is critical, this insert supports more predictable tool-change intervals and contributes to higher overall equipment effectiveness.

Stable chip control and efficient cutting geometry

The MM4 chipbreaker and the 55° rhombic form are optimised for controlled chip formation across a range of cutting depths, reducing the likelihood of built-up edge and unstable chips. The insert’s clearance angle of 11° and a 0.8 mm corner radius balance strength and surface finish, while the T3 plate thickness provides reliable seating in standard insert pockets. These geometry choices translate into consistent cutting forces, easier chip evacuation, and improved process repeatability on continuous and batch turning operations.

Clear economic advantages and workshop compatibility

By improving edge life and chip behaviour, the design lowers tooling consumption and machine downtime, delivering a positive cost-in-use effect for volume machining of stainless steel and difficult-to-cut alloys. The insert fits common toolholders for the DPGT series, and the tolerance class G supports reproducible positioning and stable clamping. For job shops and production lines seeking a balance of productivity and reliability, this grade offers a pragmatic solution that reduces rework and increases productive machining time.

Practical use cases and support for selection

Typical applications include general turning and semi-finish operations in stainless steel and nickel-base superalloys where thermal load and material adhesion are issues. The insert’s balanced geometry makes it suitable for both conventional turning and light interrupted cuts when combined with appropriate cutting data.
