CNMG120408-RM5 WMP30G – Turning insert (Tiger·tec Gold) for rostfreier Stahl, Walter Tools

The CNMG120408-RM5 WMP30G is a rhombic 80° indexable turning insert designed for secure chip control and reliable machining in rostfreier Stahl applications

• Tiger·tec Gold coating for extended tool life
• Optimised RM5 chipbreaker for stable chips
• Rhombic 80° geometry for versatile turning

Longer tool life when machining rostfreier Stahl

The coated carbide grade from the Tiger·tec Gold family is formulated for the demands of rostfreier Stahl: materials that tend to be tough and to form built-up edge. The WMP30G grade promotes stable cutting-edge behaviour and reduces premature wear, which in turn increases tool change intervals and stabilises component quality. The combination of a modern coating system with a dedicated substrate supports higher cutting speeds while maintaining flank and crater wear control, translating into lower production interruptions and predictable process windows.

Predictable chip formation and process security

The insert’s RM5 chipbreaker is engineered to produce short, controllable chips across common turning operations. This chip control reduces the risk of entanglement and improves surface integrity, particularly when machining ductile rostfreier Stahl. The negative rake (0°) geometry and rhombic 80° form balance cutting edge strength with accessibility for varied turning tasks. The 0.8 mm corner radius gives a compromise between edge robustness and surface finish capability, enabling both stable roughing passes and consistent finishing performance when properly applied.

Practical integration into turning operations

Marked CNMG120408-RM5, the insert fits standard toolholders for 80° rhombic plates and is suitable for users seeking reproducible results in rostfreier Stahl production. Its geometry and grade support reliable cycle times and reduced scrap risk through improved edge stability and chip flow. Where process consistency is essential, the Tiger·tec Gold series provides standardised behaviour across batches, simplifying tool selection and machine set-up. Consideration of cutting data, coolant strategy and holder rigidity will further optimise the insert’s performance in daily production.
