CNMG120412-MS3 WSM01 indexable turning insert — rhombic 80°, 1.2 mm radius, Walter Tools

The CNMG120412-MS3 WSM01 is a rhombic 80° indexable turning insert designed for heavy‑duty and semi‑finishing applications on stainless steel and heat‑resistant superalloys, offering a balanced geometry for stable cutting and secure chip formation.

• Tiger‑tec Silver coating for enhanced wear resistance
• Suitable for stainless steel and superalloys
• Rhombic 80° form with 1.2 mm corner radius
• Negative 0° rake for robust cutting performance

Consistent performance for difficult materials

The WSM01 grade, part of the Tiger‑tec Silver series, is a coated carbide formulation optimised for materials in ISO groups M and S, meaning stainless steels and heat‑resistant superalloys or Titan. The combination of the substrate and coating supports stable chip control under elevated temperatures and reduces the tendency for built‑up edge formation. By selecting this insert, production planners gain a solution that maintains edge integrity during interrupted cuts and high thermal loads, which helps to reduce scrap and stabilise cycle times in serial production.

Geometry designed to increase process stability

The rhombic 80° shape with a 1.2 mm corner radius and a negative 0° rake provides a robust cutting edge for heavier engagement and controlled tool deflection. The MS3 chipbreaker is engineered to produce short, segmented chips that evacuate reliably in turning operations, improving surface finish and reducing the risk of chip entanglement. The nominal plate size and thickness code give predictable clamping and repeatable indexability, which supports reproducible toolsetting and longer in‑process runs, thereby improving overall throughput.

Application benefits and shopfloor integration

When applied to stainless steel and superalloys, this insert offers a balance between wear resistance and toughness that extends tool life without compromising dimensional accuracy. The stable cutting edge and optimised chipformer reduce downtime associated with tool change and rework. Integration into existing toolholders for CNMG‑type inserts is straightforward, enabling quick replacement and minimal spindle idle time. For machining strategies that prioritise reliable production and consistent surface quality, the Tiger‑tec Silver grade provides a cost‑efficient route to longer tool life and predictable process windows.

FAQ

What materials is this insert suitable for?
The CNMG120412-MS3 WSM01 is suitable for ISO group M (stainless steels) and S (heat‑resistant superalloys and Titan), offering secure chip formation and thermal stability for these materials.

How does the MS3 chipbreaker affect machining?
The MS3 chipbreaker promotes short, controllable chips and improves surface quality during turning, reducing the risk of chip entanglement and easing chip evacuation.

What does the negative 0° rake mean for cutting forces?
A negative 0° rake provides a stronger cutting edge and better resistance to edge chipping under heavy engagement, which supports robust cutting in interrupted or heavy turning operations.

Is this insert compatible with standard CNMG toolholders?
Yes, the CNMG120412‑MS3 geometry follows standard CNMG dimensions and is intended for use in compatible indexable turning toolholders for secure seating and repeatable indexing.

How does the Tiger‑tec Silver series benefit production environments?
Tiger‑tec Silver coatings enhance wear resistance and thermal protection, increasing tool life and process reliability for serial production on demanding materials.
