CNMG120412-RM5 WSM30S — Turning insert (Rhombus 80°, Tiger·tec Silver) by Walter Tools

The CNMG120412-RM5 WSM30S is a rhombic 80° turning insert engineered for machining stainless steels and heat‑resistant superalloys in demanding production environments.

• Tiger·tec Silver coating, high heat resistance
• Optimised RM5 chipformer for reliable chip control
• Rhombic 80° geometry for versatile turning applications
• Negative 0° relief with 1.2 mm corner radius

Consistent performance where temperatures climb

The Tiger·tec Silver grade delivers a coating architecture designed for thermal stability and reduced flank wear, which is particularly beneficial when machining heat‑sensitive grades. The WSM30S cutting grade is a coated carbide developed for difficult‑to‑machine alloys; this results in a more stable cutting edge and extended edge life under elevated cutting temperatures. By favouring thermal resistance over aggressive toughness, the insert helps to avoid rapid deterioration of the tool flank and supports predictable tool change intervals, improving overall process reliability.

Controlled chips and fewer interruptions

The integrated RM5 chipformer is engineered to break and evacuate chips consistently across a range of feeds and depths of cut. Controlled chip flow reduces the risk of entanglement, protects the workpiece surface and limits machine downtime caused by chip interference. The insert’s negative 0° relief increases edge strength for interrupted cuts and heavy engagement, so tool failure is less likely in unstable cutting conditions. As a result, cycle times are maintained and throughput becomes more predictable.

Geometry that balances versatility and security

A rhombic 80° shape offers a broad contact balance suitable for both finishing and semi‑roughing passes. The 1.2 mm corner radius provides a compromise between edge strength and surface finish; small enough to achieve reasonable surface quality, yet large enough to resist chipping during heavier cuts. The geometry nomenclature and thickness designation are optimised for turners who require a reliable entry and exit behaviour while maintaining the stability of the cutting edge throughout the operation.

Tailored for stainless steels and superalloys

Specified for material groups S / M (heat‑resistant superalloys and stainless steels), this insert supports applications where poor thermal conductivity and work‑hardening are common challenges. The grade and chipbreaker combination helps to prevent built‑up edge and encourages stable chip segmentation, which is essential when machining alloys that generate continuous, stringy chips. Where surface integrity and repeatable component quality are priorities, the material compatibility of this insert delivers consistent, measurable benefits.

FAQ

Which materials is the insert suitable for?
The CNMG120412-RM5 WSM30S is designed for stainless steels (M) and heat‑resistant superalloys / titanium‑based materials (S) according to its S / M designation.

What role does the RM5 chipformer play?
The RM5 chipformer on the CNMG120412-RM5 WSM30S promotes controlled chip breaking and evacuation, reducing the risk of chip entanglement and protecting surface quality.

How does the Tiger·tec Silver coating help in production?
Tiger·tec Silver on this insert increases thermal resistance and reduces flank wear, which supports longer tool life and greater process stability in high‑temperature cutting.

Is the geometry suitable for interrupted cuts?
Yes; the negative 0° relief and 1.2 mm corner radius provide enhanced edge strength for interrupted and heavy cuts, improving reliability in demanding operations.

Can this insert be used for finishing as well as roughing?
The rhombic 80° geometry and moderate corner radius make the CNMG120412-RM5 WSM30S versatile for both semi‑roughing and finishing passes, depending on machine stability and cutting parameters.
