CNMG120412-NRS WSM30S turning indexable insert by Walter Tools — Tiger·tec Silver coated, rhombic 80° geometry

CNMG120412-NRS WSM30S is a coated turning insert designed for machining stainless steels and high‑temperature alloys with robust chip control and high process security

• Tiger·tec Silver coated grade WSM30S
• For stainless steels and superalloys
• Rhombic 80° form for versatile access
• Corner radius 1.2 mm for edge stability

Improved reliability when machining stainless steels and superalloys

The WSM30S grade, developed within the Tiger·tec Silver family, combines a wear‑resistant coating with a coated carbide substrate to handle the thermal and mechanical loads typical of stainless steels and superalloys. The insert’s formulation supports secure chip formation, which reduces the tendency for built‑up edge and unstable cutting forces. This results in more consistent cycle times and fewer unexpected tool changes, improving overall process reliability for serial production and demanding one‑off components.

Predictable edge life and robust cutting geometry

With a rhombic 80° shape and a corner radius of 1.2 mm, the geometry balances accessibility and strength: the face angle offers good tool life while permitting favourable approach angles for turning operations. The negative 0° relief increases edge robustness under interrupted cuts and heavy engagement. These design choices translate into predictable tool wear, reduced rework and a measurable improvement in machining uptime for parts made from tough, work‑hardening materials.

Efficient chip control that enhances surface quality

The NRS chipbreaker is engineered to produce short, controllable chips on materials that are prone to long, stringy chip formation. Combined with the coating characteristics of the Tiger·tec Silver series, the insert helps to avoid surface damage from chip entanglement and minimizes secondary machining. The controlled chip flow also supports safer automation and easier swarf management at higher material removal rates, leading to a better surface finish with fewer manual interventions.

Seamless integration into production and tool systems

The ISO designation and standard CNMG form ensure compatibility with common toolholders and clamping systems, making the insert straightforward to introduce into existing tool inventories. The CNMG120412‑NRS WSM30S offers a practical balance of performance and handling: robust cutting edges reduce the frequency of index changes and the coated grade simplifies tool‑system planning.

FAQ

Is this insert suitable for machining stainless steels?

Yes. The CNMG120412‑NRS WSM30S grade is formulated for stainless steels (ISO group M) and offers coating and geometry features that promote secure chip formation and reduced built‑up edge.

Can this insert be used on heat‑resistant superalloys and titanium?

The Tiger·tec Silver WSM30S grade is specified for work in ISO group S materials, so it is suitable for many heat‑resistant superalloys and titanium, where thermal resistance and edge stability are critical.

What benefit does the NRS chipbreaker provide?

The NRS chipbreaker generates short, controllable chips that reduce entanglement and improve swarf handling, which helps to protect the workpiece surface and supports safer automated machining.

What does the rhombic 80° form mean for application flexibility?

A rhombic 80° insert offers a combination of entry angle and edge strength that is useful for a wide range of turning tasks, providing good tool access while maintaining robust cutting performance.
