High-performance cutting for demanding alloys

The combination of the WSM20S grade and Tiger·tec Silver technology ensures reliable performance when machining tough materials such as rostfreier Stahl and heat-resistant superalloys. The coated cemented carbide substrate supports a stable cutting edge and reduced wear rates, which translates into longer tool life and fewer interruptions in the production flow. The description of the grade indicates its specific design for difficult-to-machine alloys; in practice this means improved process security and consistent surface quality on components that generate high temperatures and tend to work-harden.

Predictable chip control and edge stability

Thanks to the NMS chipbreaker and the insert’s geometry, chip formation is controlled and evacuation is promoted even under heavy cutting conditions. The rhombic 55° shape and a 0.4 mm corner radius provide a balance between strength and versatility, allowing both roughing and medium finishing passes with a stable cutting edge. Explained simply: the chipbreaker shapes the swarf to avoid entanglement and reduces the risk of built-up edge, while the robust geometry protects the cutting edge against thermal and mechanical shock.

Robust geometry for industrial throughput

A negative 0° rake and a solid mounting form deliver mechanical rigidity that suits interrupted cuts and heavy depths of cut. The insert’s DNMG150404-NMS designation defines the basic geometry and size, making it compatible with standard clamping systems for turning tools. For operations where repeatability and low vibration are priorities, the insert’s execution and tolerance class M contribute to constant results and easier process setting. The coated grade supports higher cutting parameters compared with uncoated grades, so cycle times can be reduced while maintaining surface integrity.

Integration into production and handling advantages

The insert’s standardized form and clear grade coding make tool management straightforward: stocks can be rotated, and tool change procedures remain consistent across batches. As a component of the Tiger·tec Silver family, the cutting grade is designed to cover a wide range of applications, simplifying the choice of tooling for mixed-production environments.

FAQ

What materials is this insert suitable for?
The DNMG150404-NMS WSM20S insert is specified for rostfreier Stahl and for heat-resistant superalloys and titanium, covering the ISO M and S groups.

What does the WSM20S grade offer compared with general-purpose grades?
WSM20S, part of the Tiger·tec Silver family, offers enhanced thermal stability and edge protection, resulting in longer tool life when machining tough, heat-prone alloys.

How does the NMS chipbreaker affect machining?
The NMS chipbreaker shapes and breaks chips reliably, improving evacuation and reducing the risk of built-up edge during turning operations with the DNMG150404-NMS geometry.

Is the insert suitable for interrupted cuts and heavy depths of cut?
Yes; the negative 0° rake and robust rhombic geometry provide the rigidity and edge strength required for interrupted cuts and higher material removal rates.

Which toolholders are compatible with this insert?
Any standard DNMG indexable turning toolholder that accepts DNMG150404 inserts will be compatible; ensure the clamping system matches the insert’s negative seating form.
