CNMG120416-RM5 WSM30S indexable turning insert — Walter Tools, Tiger·tec Silver coated for stainless steels and superalloys

The CNMG120416-RM5 WSM30S is an indexable turning insert engineered for stable performance in rostfreier Stahl and heat-resistant alloys, featuring a rhombic 80° geometry for versatile turning tasks.

• Tiger·tec Silver coated carbide grade WSM30S
• Designed for rostfreier Stahl and superalloys
• Rhombic 80° insert with 1.6 mm corner radius
• Negative 0° rake; RM5 chipbreaker for tight control

Consistent cutting performance for demanding alloys

The coated carbide WSM30S grade, using Tiger·tec Silver technology, is formulated to maintain a stable cutting edge under thermal and mechanical stress. This results in predictable tool life and fewer unscheduled tool changes when machining stainless steels and nickel-based superalloys. The insert’s composition promotes controlled chip formation and reduces edge build-up, which directly supports higher process reliability and improved component quality in serial production.

Geometry that combines strength with precision

The rhombic 80° shape and a 1.6 mm corner radius provide a compromise between edge strength and surface finish. The negative 0° clearance offers extra support to the cutting edge for interrupted cuts and hard-facing conditions, while the RM5 chipbreaker is optimised for tight chip control in demanding materials. Together, these features enable robust turning with reduced vibration and consistent dimensional results, particularly in roughing-to-finishing transitions.

Practical advantages for workshop productivity

As an indexable turning insert, the item reduces setup time and minimises tooling inventory by allowing multiple indexings per insert. The combination of a proven coating system and a stable chipformer lowers machining costs through extended life and fewer regrinds. For shop floors working with mixed batches of stainless steels and heat-resistant alloys, this grade offers versatility and dependable performance that supports continuous production flow.

Application guidance and machining notes

The insert is particularly suited to turning operations on materials classified under ISO groups M and S, meaning rostfreier Stahl and heat-resistant superalloys including titanium grades. For best results, select cutting parameters that balance moderate cutting speed with stable feed to ensure the WSM30S coating supports steady thermal conditions; the RM5 chipbreaker helps maintain short, manageable chips under these regimes. For specialised applications or uncertain process windows, technical consultation is recommended to confirm optimal parameters.

FAQ

Is this insert suitable for stainless steels?
Yes. The CNMG120416-RM5 WSM30S from Walter Tools is specifically designed for rostfreier Stahl (ISO group M) and provides stable chip formation and edge life in these materials.

Can the insert be used on nickel-based superalloys or titanium?
The WSM30S grade is intended for hard-to-machine materials, including heat-resistant superalloys (ISO group S); consult machining data for parameter adjustment when working with titanium alloys.

What does the RM5 chipbreaker deliver in practice?
The RM5 chipbreaker on the CNMG120416-RM5 promotes short, controlled chips and reduces the risk of chip entanglement, improving surface quality and process security in turning operations.

How does the negative 0° clearance affect machining?
A negative 0° clearance increases edge support and robustness, making the insert more resistant to cutting edge chipping during interrupted cuts and heavy radial engagement.

What advantages does the Tiger·tec Silver coating provide?
Tiger·tec Silver enhances wear resistance and thermal stability of the coated carbide, contributing to longer tool life and consistent performance across serial production.
