CNMG190612-NRS WSM20S — indexable turning insert, Tiger·tec Silver, Walter Tools

The CNMG190612-NRS WSM20S is an indexable turning insert engineered for heavy and heat‑resistant materials, offering stable cutting performance in rostfreier Stahl and superalloys.

• Tiger·tec Silver coated grade WSM20S
• For rostfreier Stahl and superalloys
• Rhombic 80° form, 1.2 mm nose radius
• NRS chipbreaker, negative 0° relief

High‑temperature stability and consistent performance for production

The Tiger·tec Silver coating combined with the WSM20S grade provides enhanced heat resistance and wear control, which translates into longer tool life and fewer interruptions in a production environment. For shops facing thermal loads and built‑up edge when machining rostfreier Stahl, this combination improves chip formation and protects the cutting edge against premature wear. The coated carbide substrate supports higher cutting parameters than uncoated grades, enabling a more economical process by reducing insert changes and machine downtime.

Geometry and chip control that improve process reliability

A Rhombic 80° insert form with a 1.2 mm corner radius and the NRS chipbreaker are designed to produce stable, manageable chips and a predictable cutting force. The negative 0° relief offers robustness at the cutting edge, making the insert suitable for interrupted cuts or tougher workpiece conditions. These geometric choices reduce vibration and help maintain dimensional accuracy, which benefits batch production and tight tolerance turning operations. The result is a more repeatable process and improved surface quality on the finished part.

Application range and workshop integration for machining strategies

This insert is specified for ISO groups M and S, meaning it is intended for rostfreier Stahl and heat‑resistant superalloys (including certain titanium applications). Its tolerance class M ensures consistent fit and repeatable seating in standard tool holders, simplifying tool management across milling and turning setups. The compact 19 mm inscribed circle and thickness designation 06 make it compatible with a wide range of turning tool systems, while the clear material suitability reduces the need for trial‑and‑error in production planning.

FAQ

What materials is this insert best suited for?
The CNMG190612-NRS WSM20S from Walter Tools is designed primarily for rostfreier Stahl and heat‑resistant superalloys (ISO groups M and S), offering optimised chip formation and thermal stability.

How does the NRS chipbreaker affect machining?
The NRS chipbreaker promotes short, controlled chips and steady cutting forces; in combination with the Tiger·tec Silver coating on the WSM20S grade, it supports consistent surface finish and fewer interruptions.

Is the negative 0° relief suitable for interrupted cuts?
Yes; the negative 0° relief increases edge strength and resistance to shock, making the insert robust for interrupted cuts or less stable clamping conditions.

What does the 1.2 mm corner radius mean for surface finish?
A 1.2 mm nose radius balances strength and finish: it increases edge durability while producing a good surface quality on turned components, particularly when machining tough alloys.

Can this insert be used in standard CNMG tool holders?
The CNMG190612‑NRS geometry and tolerance class M are compatible with standard CNMG holders; proper clamping and seat cleanliness are recommended to ensure repeatable performance.
