CNMG120412-RM5 WSM10S indexable turning insert — Tiger·tec Silver, for stainless steel and superalloys (Walter Tools)

The CNMG120412-RM5 WSM10S is a rhombic 80° indexable turning insert engineered for heavy and difficult machining of stainless steel and heat‑resistant superalloys, providing consistent chip control and long edge life.

• Tiger·tec Silver coated carbide insert
• Designed for stainless steel and superalloys
• Negative 0° geometry for stable cutting
• 1.2 mm corner radius for robust edge life

Improve process stability with a geometry built for heavy cuts

The combination of the Rhombic 80° form and Negative 0° free angle delivers increased cutting stability under intermittent or interrupted cuts. The insert’s geometry reduces axial and radial vibration, which translates into fewer surface defects and repeatable component quality. For production environments where component consistency matters, this geometry supports predictable tool behaviour and helps maintain cycle time targets without sacrificing finish.

Longer tool life through advanced coating and grade technology

The Tiger·tec Silver coating together with the WSM10S grade produces a coated carbide surface that resists heat build‑up and abrasive wear when machining demanding alloys. This grade is tailored to ensure stable chip formation and a durable cutting edge when working with stainless steel (ISO M) and heat‑resistant superalloys and titanium (ISO S). The result is an improved cost per component thanks to fewer insert changes and more consistent tool performance.

Controlled chips and edge robustness for safer production

The RM5 chipbreaker and a 1.2 mm corner radius provide a balance between edge strength and chip control, suited to heavier depths of cut while maintaining manageable swarf. A larger corner radius increases edge durability and reduces the risk of premature chipping, which is particularly valuable when machines operate under variable conditions. Where surface quality and repeatability are required, this combination helps reduce rework and scrap.

Practical application notes and holder selection

This insert performs best in rigid toolholders that match the CNMG seat and support the Rhombic 80° profile; secure clamping and correct rake compensation are essential for optimising edge life. When replacing conventional grades, consider modest reductions in cutting speed and incremental increases in feed to validate the WSM10S response on specific alloys. Documentation of initial cutting data will aid in rapidly achieving stable parameters for series production.

FAQ

What materials is this insert suitable for?
The CNMG120412-RM5 WSM10S from Walter Tools is designed for stainless steel (ISO M) and for heat‑resistant superalloys and titanium (ISO S), offering good chip control and edge stability in those groups.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating on the WSM10S grade improves heat and wear resistance, which typically extends insert life and reduces the frequency of tool changes in serial production.

What does the 0° (negative) free angle mean in practice?
A negative 0° geometry increases cutting edge support and reduces vibration under heavy loads, making the insert suitable for interrupted cuts and unstable setups where a more robust edge is required.

Which chipbreaker should be selected for mixed operations?
The integrated RM5 chipbreaker on this insert provides a compromise between chip control and edge strength, suitable for a range of feeds and depths typical in finishing to medium roughing operations.

Is the corner radius of 1.2 mm suitable for precision finishes?
The 1.2 mm corner radius favours edge robustness and process reliability; for ultra‑fine finishes smaller radii may be preferable, but 1.2 mm balances durability and surface quality for many production tasks.
