DNMG150612-NRS WSM20S — Indexable turning insert for rostfreier Stahl and superalloys by Walter Tools

DNMG150612-NRS WSM20S is an indexable turning insert designed for tough materials and high-temperature alloys, offering robust edge stability and consistent performance in heavy-duty turning operations.

• Tiger-tec Silver coating for wear resistance
• Grade WSM20S for heavy-duty materials
• Rhombus 55° geometry for versatile turning
• 0° (negative) relief angle for secure edges

High-performance grade for demanding materials

The WSM20S grade, part of the Tiger-tec Silver family, is engineered as a coated carbide solution for machining rostfreier Stahl and heat-resistant superalloys. Its coating system improves surface hardness and thermal resistance, which translates into stable chip formation and reduced edge wear during prolonged cuts. For production environments where tool life and process consistency matter, this insert provides a reliable balance between wear resistance and fracture toughness, helping to lower tooling costs per component and maintain consistent cycle times.

Geometry and chip control that protect the cutting edge

The insert's rhombus 55° shape and NRS chipbreaker are configured to support controlled chip evacuation and adaptable cutting directions. The 0° (negative) relief angle increases cutting-edge support under heavy radial loads, while the 1.2 mm corner radius contributes to a reinforced cutting edge for interrupted cuts or uneven workpiece surfaces. These design choices reduce the risk of edge chipping and improve surface finish in roughing-to-finishing sequences. For operators unfamiliar with technical terms: the chipbreaker guides and splits chips to prevent long, tangled swarf and the negative relief angle provides extra support behind the cutting edge.

Practical advantages for production and tool management

The insert is supplied in the widely used DNMG footprint, enabling straightforward integration into existing toolholders and reducing changeover complexity. Its specification supports machining strategies that prioritise productivity—longer tool life and fewer interruptions mean improved machine uptime. The variant is particularly suitable where process reliability and repeatable results are required in series production. For offline programming or process planning, note the grade and geometry to match cutting data with the chosen holder and machine capability, ensuring optimal cutting speeds and feeds for rostfreier Stahl and related alloys.

FAQ

Which materials are best machined with this insert?
The DNMG150612-NRS WSM20S insert from Walter Tools is optimised for machining rostfreier Stahl and can also handle heat‑resistant superalloys and titanium applications depending on geometry.

What does the WSM20S grade provide in terms of performance?
WSM20S, part of the Tiger‑tec Silver family, offers enhanced thermal stability and wear resistance, delivering stable chip formation and extended tool life under demanding turning conditions.

How does the insert geometry affect operation?
The rhombus 55° shape with a 1.2 mm corner radius and the NRS chipbreaker give a good balance between strength and chip control, supporting heavy cuts and improved surface finish in interrupted and continuous turning.

Is this insert compatible with standard DNMG toolholders?
Yes, the insert matches the DNMG footprint and is suitable for standard DNMG toolholders, facilitating easy integration and quick changeover in production environments.

What cutting situations benefit most from the 0° (negative) relief angle?
The 0° (negative) relief angle increases support behind the cutting edge, making the insert particularly robust for heavy or unstable cuts where edge chipping risk is higher.
