CCMT060208-MM4 WSM20S – Rhombic 80° turning insert, Tiger‑tec Silver (Walter Tools)

A high‑performance CCMT060208-MM4 WSM20S indexable turning insert optimised for demanding stainless steel and superalloy applications, delivering stable edges and controlled chip formation.

• Tiger‑tec Silver coating for heat stability
• Stable chip control with MM4 chipbreaker
• Rhombic 80° geometry for versatile turning
• 0.8 mm corner radius for dependable edge life

Longer tool life when machining stainless steel

The coated carbide grade WSM20S from the Tiger‑tec Silver family is designed to cope with the specific challenges of stainless steel. The combination of a thermally resistant coating and a robust substrate reduces heat‑related wear and supports stable cutting edges, which translates into longer tool life and fewer interruptions for insert changes. For shops processing corrosion‑resistant alloys, this means less inventory turnover and improved process reliability without sacrificing surface quality.

Precise chip control reduces downtime

The integrated MM4 chipbreaker promotes predictable chip formation and evacuation, reducing the risk of entanglement and workpiece damage. Controlled chips ease swarf handling and lower machine cleaning intervals, which in turn improves effective machining time. The positive effect on surface finish and tool behaviour is particularly noticeable in interrupted cuts and deep turning operations, where consistent chip geometry helps maintain cycle stability.

Geometry that balances strength and accessibility

The Rhombic 80° shape with a 7° clearance angle delivers a good compromise between cutting edge strength and accessibility for external and internal turning. The 0.8 mm corner radius supports durable cutting edges for medium‑to‑heavy cuts while still allowing acceptable surface integrity for finishing passes. This geometry is flexible across a range of turning tasks and supports close tolerances in series production, particularly where tool life and repeatability are priorities.

Application guidance and process benefits

This insert is suitable for machining materials classified under ISO groups M (stainless steel) and S (heat‑resistant superalloys and titanium), where heat resistance and edge stability are essential. The coated carbide construction aids thermal management and wear resistance during sustained cutting, helping to achieve consistent results in both roughing and semi‑finishing operations. When paired with appropriate insert seatings and stable toolholding, users can expect a measurable improvement in process security and repeatability.

FAQ

Which materials is this insert intended for?
The CCMT060208-MM4 WSM20S insert is engineered primarily for stainless steel (ISO group M) and also performs well on heat‑resistant superalloys and titanium (ISO group S), offering good chip control and edge stability.

What advantages does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver improves thermal resistance and wear behaviour on the cutting edge, helping the WSM20S grade to maintain performance under high temperatures and abrasive conditions common with stainless steel.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker produces predictable, manageable chips that reduce swarf issues and improve surface finish, which increases uptime and lowers the likelihood of workpiece marking during turning.

Is the geometry suitable for finishing passes?
With a Rhombic 80° form and a 0.8 mm corner radius, the insert provides a balance between strength and finish capability; it is suitable for robust semi‑finishing and can also be used for finishing with adjusted cutting parameters.

What should be considered when integrating this insert into existing processes?
Ensure secure toolholding and appropriate coolant application for stainless steel to exploit the WSM20S grade fully; the insert’s properties favour consistent feeds and controlled chip evacuation for reproducible production results.
