CNMG120408-RM5 WSM10S turning insert – negative, rhombic 80° by Walter Tools

The CNMG120408-RM5 WSM10S is a negative, rhombic 80° indexable turning insert designed for demanding machining of rostfreier Stahl and heat-resistant alloys in production environments

• Tiger·tec Silver coated carbide grade WSM10S
• Optimised for rostfreier Stahl and superalloys
• RM5 chipbreaker for consistent chip control

Stable machining of rostfreier Stahl and superalloys

The Tiger·tec Silver WSM10S grade combines a wear-resistant coating with a substrate engineered for thermal resilience, delivering consistent edge life when machining challenging materials such as rostfreier Stahl (ISO group M) and heat-resistant superalloys or titanium (ISO group S). This engineered balance reduces the risk of built-up edge and flank wear, which translates into fewer tool changes and improved process reliability. The coded grade and coating technology are designed to support higher cutting temperatures, enabling longer uninterrupted cycles in series production.

Reliable chip control and improved surface finish

Equipped with the RM5 chipbreaker and a 0.8 mm corner radius, the insert provides predictable chip formation across a range of feeds and depths of cut. The negative 0° relief geometry and rhombic 80° shape enhance rigidity in facing and turning operations, promoting stable cutting forces and reduced vibration. The outcome is better dimensional stability and a finer surface finish, especially important when producing components with tight tolerances or when secondary finishing steps must be minimised.

Productivity gains through process security

The hardened and coated carbide construction of this indexable insert supports repeatable performance in batch and continuous production. By maintaining a stable cutting edge and enabling controlled heat dissipation, the insert contributes to longer tool life and a lower cost per component. Integration into standard toolholders is straightforward due to the established CNMG form factor, which helps reduce set-up times and simplifies inventory management for workshop operations that require dependable turning solutions.

Practical benefits for workshop planning

Because the insert is part of the Tiger·tec Silver series and specified as WSM10S, procurement and tool planning become more transparent: the grade is well documented for rostfreier Stahl and S-group materials, and performance data can be compared across similar Tiger·tec Silver grades. The robust chip control also decreases the likelihood of machine downtime caused by poor chip evacuation, supporting smoother production flow and predictable throughput.

FAQ

What materials is this insert suitable for?
The CNMG120408-RM5 WSM10S insert is specified for rostfreier Stahl (ISO M) and heat-resistant superalloys/titanium (ISO S), reflecting the Tiger·tec Silver grade’s thermal and edge-strength properties.

How does the RM5 chipbreaker improve machining?
The RM5 chipbreaker on this Walter Tools insert promotes controlled chip formation and evacuation, reducing built-up edge and enabling more stable cutting conditions across typical turning feeds and depths.

Is the negative 0° relief suitable for heavy cuts?
Yes, the negative 0° relief combined with the rhombic 80° form increases insert rigidity, making the geometry well suited to heavier cuts and interrupted cuts where edge strength is critical.

What effect does the 0.8 mm corner radius have on surface finish?
A 0.8 mm corner radius balances edge strength and surface quality; it helps maintain a stable cutting edge while producing a consistent finish without frequent edge breakage.

Can this insert be used in standard CNMG toolholders?
The CNMG120408-RM5 WSM10S follows the CNMG form factor and fits conventional CNMG-compatible toolholders, simplifying tool changeover and inventory management.
