CNMG190612-RM5 WMP30G — Turning indexable insert, Tiger·tec Gold, by Walter Tools

The CNMG190612-RM5 WMP30G is a rhombic 80° turning indexable insert engineered for medium to robust machining of stainless steels, offering secure chip formation and consistent performance.

• Tiger·tec Gold coating for stainless steels
• RM5 chipbreaker for secure chip control
• Rhombic 80° form for versatile turning
• 1.2 mm corner radius for robust edge strength

Consistent chip control for uninterrupted production

The combination of the RM5 chipbreaker and the Tiger·tec Gold coating provides reliable chip formation when machining austenitic and other challenging stainless steels. The insert’s coated carbide grade is tailored to reduce built-up edge and to stabilise the cutting edge under elevated temperatures; as a result, process reliability and component consistency are improved. In practical terms, this leads to fewer interruptions for edge corrections and a steadier output in serial production, which supports predictable cycle times and lower rework rates.

Geometry that balances strength and versatility

The rhombic 80° geometry, paired with a negative rake of 0°, combines cutting-edge stability with broad applicability across turning operations. The 1.2 mm corner radius increases edge strength for interrupted cuts and plunge turning, reducing the risk of chipping during heavy passes. This geometry also helps maintain good surface integrity on the workpiece, making the insert suitable for both roughing and semi-finishing tasks in workshop and production environments.

Optimised for stainless steels and robust conditions

Designed for the ISO M material group, this insert supports machining strategies where material toughness and heat generation are significant concerns. The Tiger·tec Gold technology increases thermal resistance and wear stability, while the RM5 chipbreaker aids consistent chip control even under variable feed and depth conditions. The result is a combination that often improves tool life versus standard grades and reduces the frequency of insert changes, thereby lowering total process cost and improving uptime.

Practical integration and handling benefits

The insert follows the common CNMG form factor, simplifying toolholder selection and inventory management for systems already set up for rhombic 80° inserts. The clear designation assists with fast ordering and traceability on the shop floor.
