CNMG120408-MS3 WSM30S turning insert — Tiger‑tec Silver grade for rostfreier Stahl and superalloys | Walter Tools

The CNMG120408-MS3 WSM30S is a rhombic 80° indexable turning insert engineered for heavy-duty and demanding machining of rostfreier Stahl and heat‑resistant superalloys.

• Tiger‑tec Silver coated for heat resistance
• Designed for rostfreier Stahl and superalloys
• Rhombic 80° CNMG form with 0.8 mm corner radius
• MS3 chipbreaker for stable chip formation

Extended cutting performance for hard-to-machine materials

The combination of the WSM30S grade and Tiger‑tec Silver coating offers a blend of thermal stability and wear resistance that is particularly valuable when machining rostfreier Stahl and nickel‑based alloys. The coated carbide substrate reduces flank wear and supports a more consistent tool life, which in turn lowers tool change frequency and improves uptime. For production environments where component conformity and repeatability matter, the enhanced resistance to thermal softening helps maintain cutting-edge geometry over longer cycles while promoting stable chip formation under demanding conditions.

Geometry that improves process reliability and surface quality

The CNMG rhombic 80° form paired with a 0.8 mm corner radius gives a strong edge for interrupted cuts and medium to heavy turning operations. The negative 0° clearance configuration increases edge strength and reduces the risk of edge chipping during heavy engagement, while the MS3 chipbreaker is tuned to produce controllable chips and support a consistent surface finish. These geometric attributes reduce vibration and support predictable cutting forces, which benefits both tool life and component tolerance achievement in serial production.

Practical advantages and application fit for productive cutting

As an indexable insert, the CNMG120408-MS3 WSM30S is suitable for series production where process security and repeatable outcomes are priorities. The combination of grade, coating and chipbreaker offers productive cutting with lower scrap rates when matched to the correct cutting data for the material. Its compatibility with standard CNMG toolholders ensures straightforward integration into existing tool systems, and the insert’s build delivers a reliable balance between robustness and achievable surface quality for turned parts made from rostfreier Stahl or high-temperature superalloys.

FAQ

Which materials is this insert intended for?
The CNMG120408-MS3 WSM30S by Walter Tools is optimised for rostfreier Stahl (ISO group M) and heat‑resistant superalloys/Titanium (ISO group S), addressing the thermal and mechanical challenges typical of these materials.

What benefits does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating on the WSM30S grade improves thermal resistance and reduces adhesive wear, which helps maintain cutting-edge geometry and extends the usable life of the insert under high heat loads.

How does the MS3 chipbreaker influence machining?
The MS3 chipbreaker is designed to produce short, controllable chips and support consistent chip evacuation, contributing to stable cutting forces and improved surface quality when machining difficult alloys.

For which operations is the rhombic 80° CNMG geometry most suitable?
The rhombic 80° CNMG form with a 0.8 mm corner radius is well suited to medium and heavy turning, including interrupted cuts; it provides a robust edge for stable machining rather than ultra‑fine finishing tasks.
