CNMG160616-NRS WSM20S indexable turning insert — Tiger·tec Silver for stainless steels and superalloys | Walter Tools

A CNMG160616-NRS WSM20S indexable turning insert engineered for interrupted and continuous turning of rostfreie Stähle and heat‑resistant superalloys in demanding production environments.

• Tiger·tec Silver coating for heat resistance
• Designed for stainless steels and superalloys
• Rhombic 80° geometry for versatile turning
• NRS chipbreaker with 1.6 mm corner radius

Reliable machining of high‑alloy materials

The combination of the WSM20S grade within the Tiger·tec Silver family delivers enhanced thermal resistance and wear behaviour when machining stainless steels and heat‑resistant alloys. This coated carbidesort is optimised to reduce flank wear and to maintain a stable cutting edge during long cycles, which supports consistent component quality. For operations that struggle with heat‑related adhesion or edge build‑up, the specified coating technology improves tool life and reduces unplanned tool changes, translating directly into higher machine availability and lower per‑part costs. The supplied geometry is suited to applications where secure chip formation and dependable surface finish are required.

Consistent chip control and edge stability for fewer process interruptions

The integrated NRS chipbreaker and the 1.6 mm corner radius promote controlled chip formation and evacuate material reliably at typical turning feeds. A negative 0° relief helps stabilise the cut under heavy engagement, reducing vibration and the risk of chipping in tough materials. These design elements combine to produce repeatable tool performance and predictable wear patterns, which is crucial for planning tool replacement intervals and minimising scrap. Understanding chipbreaker function: it shapes the chip to break into short, manageable lengths, improving safety and allowing closer tool‑to‑part proximity in automated setups.

Productivity and process security in production

The rhombic 80° insert shape provides flexibility in approach angles and enables multiple cutting edges per insert, supporting economical use in batch production. As an indexable insert, it allows quick edge changes without regrinding, shortening downtime and increasing throughput. The geometry and grade are selected to balance toughness and wear resistance, offering repeatable results and improved surface integrity on turned parts. Combined with the brand consistency of Walter Tools, this insert is suitable for workshops and OEMs seeking predictable output and reduced process variance.

FAQ

What materials is this insert suitable for?
The CNMG160616-NRS WSM20S insert is designed primarily for rostfreie Stähle (stainless steels) and heat‑resistant superalloys, offering stable cutting and improved wear resistance in those groups.

How does the NRS chipbreaker improve production?
The NRS chipbreaker on this indexable turning insert shapes and breaks chips into short lengths, which enhances chip evacuation and reduces the risk of entanglement, supporting safer and more efficient machining.

What does the 0° (negative) relief angle mean for cutting?
A negative 0° relief increases insert strength under heavy cuts and interrupted turning; this geometry reduces vibration and supports a robust cutting edge in demanding operations.

Can the insert be re‑indexed to use multiple cutting edges?
Yes, the rhombic 80° form and indexable design allow multiple edges to be rotated into service, making the CNMG160616-NRS WSM20S an economical choice for batch and serial production.

Is this product suitable for automated or long cycle machining?
The combination of Tiger·tec Silver coating and the stable geometry provides repeatable tool life and process security, making the insert well suited to automated and long‑run turning operations.
