CNMG120408-MS3 WSM10S indexable turning insert (Rhombic 80°) – Walter Tools, Tiger·tec Silver

The CNMG120408-MS3 WSM10S is a coated carbide indexable insert engineered for robust turning of stainless steels and heat-resistant superalloys in industrial production.

• Tiger·tec Silver coated grade
• Optimised for stainless steels and superalloys
• Rhombic 80° CNMG geometry for versatile clamping
• 0.8 mm nose radius with MS3 chipbreaker

High-performance grade for demanding materials

The WSM10S grade, produced with the Tiger·tec Silver coating, offers a combination of wear resistance and thermal stability that benefits long cycle times and interrupted cuts. As a coated carbide insert developed for the machining of stainless steels and superalloys, it supports secure chip formation and reduces the risk of built-up edge. The selectable, heat-resistant coating technology is aimed at maintaining cutting-edge integrity under elevated temperatures, which in turn improves process repeatability and reduces rework.

Geometry and chip control that increase productivity

With the characteristic CNMG geometry and a rhombic 80° profile, this insert provides broad accessibility to turning applications and flexible tool-holder compatibility. The MS3 chipbreaker is tuned to promote controlled chip formation for medium to heavy cuts, improving surface finish and reducing downtime from chip-related issues. The 0° negative rake design increases edge strength for tougher engagements, while the 0.8 mm nose radius balances surface quality with robust edge life.

Reliability and reduced machining risk

Designed for production environments where consistency matters, the insert’s tolerance class and execution ensure predictable seating and repeatable results. The combination of a stable cutting edge and an optimised chipbreaker enhances both dimensional control and component finish. This leads to fewer in-process interruptions and contributes to overall line efficiency, supporting the case for cost-effective machining in serial production.

Practical application and handling advice

The insert is suitable for turning tasks where stainless steels and heat-resistant alloys challenge tool life and process stability. Use the plate with appropriate tool-holders for CNMG-style inserts and ensure machining parameters are adapted to the workpiece material and rigidity of the setup. Regular inspection of the cutting edge and correct clamping torque will secure process reliability and prolong tool-life, while correct coolant strategy will support the grade’s thermal performance.

FAQ

What materials is this insert suited for? The CNMG120408-MS3 WSM10S indexable turning insert is specified for stainless steels and heat-resistant superalloys (groups M and S), offering thermal stability and secure chip formation for these challenging materials.

How does the negative rake influence cutting performance? A 0° negative rake increases edge robustness, making the insert more resistant to edge chipping during heavy interruptions or tough engagements; this characteristic supports longer edge life for the CNMG120408-MS3 WSM10S.

What benefit does the MS3 chipbreaker provide? The MS3 chipbreaker promotes controlled chips and stable evacuation in medium to heavy turning, improving surface finish and reducing the likelihood of chip-related machine stoppages.

Is the insert compatible with standard CNMG holders? Yes, the rhombic 80° CNMG geometry matches standard CNMG tool-holders; correct clamping and seating are essential to achieve the stated tolerances and repeatable performance.

How should tool-life be maximised with this grade? Maximise tool-life by selecting cutting parameters aligned with the workpiece and machine rigidity, maintaining appropriate coolant or lubrication practices, and inspecting the insert edge regularly for wear on the CNMG120408-MS3 WSM10S.
