CNMG120412-MS3 WSM10S — Indexable turning insert, rhombic 80° with 1.2 mm corner, Walter Tools

A CNMG120412-MS3 WSM10S insert engineered for precision turning of stainless steels and heat-resistant alloys, optimised for reliable chip formation and consistent cutting performance.

• Tiger·tec Silver coating technology
• WSM10S grade for stainless and superalloys
• Rhombic 80° insert, 1.2 mm corner radius
• MS3 chipbreaker, 0° negative rake

High-performance grade for demanding materials

The WSM10S grade from Tiger·tec Silver is formulated specifically for machining stainless steels and heat-resistant superalloys, where secure chip control and thermal resistance matter. Thanks to the coated carbide technology, the insert supports stable cutting-edge behaviour under the high temperatures and built-up-edge tendency typical of these materials. This translates into fewer unplanned tool changes, more consistent part quality and a better overall process economy when compared with uncoated or general-purpose grades.

Geometry and chip control that improve cycle reliability

The rhombic 80° shape combined with the MS3 chipbreaker and a 1.2 mm corner radius provides a balance between strength and accessibility to the cutting zone. The 0° negative rake gives edge robustness for interrupted cuts and tough materials while the chipbreaker helps to generate controllable chip forms across varied feeds. These geometry features reduce the risk of edge deformation and support longer, predictable performance windows — a clear advantage in production runs that demand repeatable results.

Practical benefits for workshop and production planning

Incorporating this indexable insert into turning operations brings measurable operational benefits: improved process stability when machining stainless steels (ISO group M) and heat-resistant alloys (ISO group S), more consistent surface integrity and reduced scrap rates. The insert's specification and coating help maintain a steady cutting condition, simplifying tool planning and making it easier to standardise inserts across similar applications. For shops seeking predictable tool life and reliable component finish, the combination of grade, chipbreaker and geometry offers a technically sound solution.

FAQ

What materials is this insert suitable for?
The CNMG120412-MS3 WSM10S insert is suitable for stainless steels and heat-resistant superalloys (ISO groups M and S), leveraging the Tiger·tec Silver grade for thermal resistance and chip control.

How does the MS3 chipbreaker affect performance?
The MS3 chipbreaker on this insert is designed to promote controllable chip formation in tougher materials, helping to protect the cutting edge and maintain consistent surface quality during turning operations.

What does the 0° negative rake mean for machining?
A 0° negative rake provides a robust cutting edge that withstands higher mechanical and thermal loads, making the insert suitable for interrupted cuts and operations where edge stability is critical.

Can this insert be used for finishing and roughing?
Depending on the chosen cutting data and machine rigidity, the geometry and 1.2 mm corner radius of the insert allow for both stable roughing passes and acceptable finish results when set up appropriately.

Which Walter Tools series does this grade belong to?
The grade is part of the Tiger·tec Silver series; the CNMG120412-MS3 WSM10S insert combines this series' coating technology with a geometry tailored for demanding turning tasks.
