CCMT09T304‑MW4 WSM20S — Rhombic 80° turning insert with Tiger·tec Silver, Walter Tools

The CCMT09T304‑MW4 WSM20S is a coated turning insert designed for productive machining of stainless steel and heat‑resistant superalloys in industrial turning applications.

Tiger·tec Silver coating for heat resistance
WSM20S grade for stainless steel & superalloys
Rhombic 80° form, 7° relief for versatile turning
MW4 chipbreaker for consistent chip control

High‑temperature cutting performance for demanding alloys

The combination of the Tiger·tec Silver coating and the WSM20S carbide grade provides improved resistance to thermal loading and abrasion when machining tough materials. The coating technology enhances heat management at the cutting edge, while the grade is tuned for stable edge life during the interrupted cutting and high temperatures typical of stainless steel and nickel‑base alloys. As a result, the indexable insert delivers a reliable balance between wear resistance and toughness, reducing unplanned tool changes and supporting consistent production throughput.

Geometry tuned for stability and surface quality

The rhombic 80° shape with a 0.4 mm corner radius and a 7° relief angle offers a versatile geometry for general turning tasks and finishing passes. The moderate corner radius helps to maintain a strong cutting edge without sacrificing surface finish, and the relief angle reduces rubbing on the flank to lower cutting temperatures. The MW4 chipformer actively shapes chips for predictable evacuation, which lowers the risk of built‑up edge and improves process security. Together these features promote repeatable part quality and longer indexable insert life.

Practical benefits and process recommendations

Configured as a standard turning insert in size 09 with thickness T3, this solution integrates easily into common toolholders and machining setups. The combination of coating, grade and chip control targets operators who require productivity and reproducible results in mixed‑batch or series production. For roughing of heavy cross‑sections, consider conservative feeds to preserve the cutting edge; for finishing, the insert geometry supports superior surface integrity on stainless steel. The tolerance class M indicates suitability for applications where consistent insert geometry is essential for precision turning.

FAQ

What materials is this insert suitable for?
The CCMT09T304‑MW4 WSM20S insert is designed for stainless steel and heat‑resistant superalloys (material groups S and M), offering thermal stability and controlled chip formation for such alloys.

How does the MW4 chipbreaker affect machining?
The MW4 chipbreaker on this Walter Tools insert shapes chips for reliable evacuation, which improves process security and reduces the likelihood of built‑up edge during turning operations.

What is the benefit of the 0.4 mm corner radius?
A 0.4 mm corner radius provides a compromise between edge strength and surface finish, helping to maintain a durable cutting edge while delivering good workpiece quality in finishing passes.

Is this insert suitable for both roughing and finishing?
Yes; the geometry and coating enable productive roughing with appropriate cutting parameters and stable finishing with improved surface integrity on stainless steel.

Which series and coating technology is used on the insert?
The insert belongs to the Tiger‑tec Silver series and uses the associated coated carbide technology, optimised for thermal resistance and edge stability.
