CCMT09T302‑FM4 WMP20G — Rhombic 80° turning insert with Tiger‑tec Gold coating by Walter Tools

A CCMT09T302‑FM4 WMP20G indexable turning insert engineered for stable and productive machining of rostfreier Stahl in medium to robust cutting conditions

• Tiger‑tec Gold coating for extended tool life
• Designed for rostfreier Stahl (ISO M) machining
• Rhombic 80° geometry with 0.2 mm corner radius
• FM4 chipbreaker for reliable chip control

Consistent performance for rostfreier Stahl machining

The combination of the WMP20G grade and Tiger‑tec Gold technology delivers a balance of wear resistance and edge stability that is particularly effective when machining rostfreier Stahl. The coated cemented carbide substrate resists abrasive and adhesive wear, supporting a predictable tool life and fewer unscheduled tool changes. This results in higher process efficiency and reduced cycle variability for serial production.

Geometry that improves cutting stability and surface quality

The rhombic 80° insert shape provides versatile approach angles for turning and light profiling, while the 0.2 mm corner radius increases edge strength to withstand interrupted cuts. A 7° clearance angle reduces rubbing and heat generation at the flank, contributing to improved surface finish and longer insert life. Together these geometric choices enhance dimensional stability and help to maintain repeatable results on demanding components.

FM4 chipbreaker for controlled swarf and safer operations

The FM4 chipbreaker is configured to promote secure chip formation with the tougher behaviour of rostfreier Stahl, reducing the tendency for long, stringy chips that can foul the toolpath. Improved chip control lowers the risk of surface damage and simplifies chip evacuation, supporting safer, more efficient machining and less manual intervention during longer runs.

Application guidance and toolroom integration

This indexable insert is intended for use in standard turning toolholders compatible with CCMT‑style inserts. The combination of grade and chipbreaker suits finishing and semi‑finishing passes under medium to robust conditions on rostfreier Stahl. For optimal results, pair the insert with appropriate cutting parameters, coolant strategies and a rigid clamping system; this ensures the coated carbide edge maintains stability and reduces the likelihood of built‑up edge formation.
