CCMT120408-E47 CCMT120408-E47 WSM20S WSM20S — Indexable turning insert for stainless steel and superalloys, Tiger·tec Silver | Walter Tools

A robust indexable turning insert, the CCMT120408‑E47 WSM20S is engineered for secure chip formation and edge stability when machining stainless steel and high‑temperature superalloys in turning applications.

• Tiger·tec Silver coating for heat resistance
• Optimised E47 chipbreaker for stable chips
• Rhombic 80° geometry for versatile turning
• 0.8 mm corner radius for robust edge life

Predictable performance under high thermal and mechanical load

The coated WSM20S grade, realised through Tiger·tec Silver technology, prioritises heat resistance and edge stability. For materials classified under ISO 513 as M and S, the grade supports continuous chip formation and reduces the risk of built‑up edge, which in turn stabilises component tolerances and surface quality. This results in fewer unscheduled tool changes and more consistent process output, a clear advantage for production environments that demand repeatability and low scrap rates. The design focus is on process security and sustained cutting performance rather than one‑off speed gains.

Geometry and chip control that cut secondary operations

The combination of a Rhombic 80° form, a 7° clearance angle and the E47 chipbreaker delivers controlled chip breaking and secure seating in the toolholder. The 0.8 mm corner radius increases edge robustness for interrupted cuts and reduces edge chipping, while the chipbreaker geometry supports short, controllable chips on ductile and work‑hardening stainless grades. These features lower the probability of tool‑related surface defects, meaning fewer finishing passes and reduced cycle times for batch production.

Integration into machining processes for reliable productivity

With tolerance class M and the compact insert format, the component integrates smoothly into standard turning toolholders for CNC lathes. The indexable insert format simplifies tool change procedures and enables predictable inventory management for workshops. Selection of this insert supports a rational machining strategy: focus on stable cutting conditions and long tool life rather than extreme feeds. For shops aiming to balance throughput and component quality, the insert contributes to a demonstrable improvement in uptime and consistency.

FAQ

What materials is this insert suitable for?
The CCMT120408‑E47 WSM20S is designed primarily for stainless steel (ISO group M) and for heat‑resistant superalloys and titanium (ISO group S), using the Tiger·tec Silver grade to improve heat and wear resistance.

How does the E47 chipbreaker affect machining performance?
The E47 chipbreaker produces short, controlled chips on ductile and work‑hardening materials, improving surface finish and reducing the risk of chip entanglement compared with generic geometries.

Can the insert be used for heavy interrupted cuts?
With a 0.8 mm corner radius and a robust coated grade, the insert offers enhanced edge strength for interrupted cuts; however, toolholder rigidity and machine stability should be verified for very heavy interruptions.

What advantage does the Tiger·tec Silver technology provide?
Tiger·tec Silver coating increases thermal resistance and edge stability, which translates into longer effective tool life and more consistent component quality under elevated cutting temperatures.

Is the insert available in other chipbreaker or grades?
Walter Tools offers multiple chipbreaker geometries and grades; for comparable operations the WSM20S grade with the E47 breaker is optimised for the described M and S applications.
