DNMG150608-NFT WSM20S – Indexable turning insert, Tiger·tec Silver coating, 0° negative rake (Walter Tools)

The DNMG150608-NFT WSM20S is a rhombic turning insert intended for machining stainless steels and heat‑resistant alloys, offering robust chip control and reliable edge stability for demanding production environments

• Tiger·tec Silver coating for higher wear resistance
• WSM20S grade for stainless and heat‑resistant alloys
• Rhombic 55° geometry for versatile turning
• NFT chipbreaker for stable chip formation

Improved cutting performance in stainless and superalloys

The coated carbide grade WSM20S, part of the Tiger·tec Silver series, is engineered specifically for the challenges of stainless steels and superalloys. The combination of a wear‑resistant coating and a substrate optimised for heat resistance reduces adhesion and flank wear during interrupted or continuous cuts. This results in longer tool life and fewer unscheduled tool changes, which contributes directly to more predictable machining cycles and improved overall productivity.

Reliable geometry and chip control for steady results

A Rhombic 55° insert form combined with an NFT chipbreaker delivers consistent chip segmentation and evacuation even under adverse cutting conditions. The 0° negative rake geometry strengthens the cutting edge and supports stable cutting forces, while the 0.8 mm corner radius provides a balance between edge strength and surface finish. Together these features promote repeatable part quality and reduce the risk of built‑up edge formation when turning tough, work‑hardening stainless materials.

Process efficiency through reduced downtime and consistent quality

By favouring stable chip formation and a robust edge, this insert helps to shorten non‑productive time associated with tool changes and rework. The wear resistance offered by the Tiger·tec Silver technology supports higher metal removal rates where the machine and component tolerances allow, improving the cost‑per‑part ratio in medium to large‑batch production. Selecting the appropriate grade and chipbreaker for the specific operation contributes to predictable tool life and measurable process reliability.

Practical integration into production workflows

The insert is supplied in the standard DNMG format with a plate size of 15 mm and plate thickness 06, making it compatible with common turning toolholders used for finishing and semi‑finishing operations. Its application focus on stainless steels and heat‑resistant alloys makes it suitable for medical components, food‑grade parts and aerospace fittings where material toughness and thermal load demand a stable cutting edge. For optimal results, match insert geometry and grade to the workpiece alloy and machining strategy.

FAQ

What materials is this insert designed to machine? The DNMG150608-NFT WSM20S insert from Walter Tools is designed primarily for stainless steels and heat‑resistant superalloys, addressing the thermal and adhesion challenges of these materials.

How does the NFT chipbreaker improve machining? The NFT chipbreaker on the Walter Tools insert promotes consistent chip segmentation and evacuation, which reduces the risk of chip entanglement and supports steady cutting forces for improved surface quality.

What is the significance of a 0° negative rake for this insert? A 0° negative rake increases edge strength and enables more robust cutting under higher mechanical and thermal loads, making the insert suitable for demanding turning of tough alloys.

Can this insert be used for finishing and semi‑finishing operations? Yes, the Rhombic 55° form and 0.8 mm corner radius make the insert suitable for finishing and semi‑finishing, offering a compromise between surface finish and edge strength.

Is the DNMG150608-NFT WSM20S compatible with standard DNMG toolholders? The insert follows the DNMG designation and typical dimensions (plate size 15, thickness 06), so it fits standard DNMG toolholders when the holder clamping and geometry match the application.
