Higher productivity through proven coating technology

The combination of Tiger·tec Gold coating and the WMP20G grade delivers a measurable improvement in cutting-edge robustness and wear resistance when machining stainless steel. Coated carbide provides a thermal and mechanical barrier that reduces flank wear and supports a consistent machining regime under moderate to robust cutting parameters. This results in fewer tool changes, better tool-cost efficiency and stable cycle times for series production, making the insert a pragmatic choice where process reliability and throughput matter.

Design features that create reliable surface quality

The insert’s FM4 chipbreaker and round insert geometry promote controlled chip flow and minimise built-up edge formation typical of stainless steel workpieces. The 7° clearance angle supports a predictable cutting engagement while the specified plate size and thickness provide mechanical stability in interrupted cuts. The design reduces the risk of edge chipping and supports a consistent surface finish — an advantage for shops aiming for repeatable component tolerances and reduced in-process scrap.

Practical handling and application guidance

The RCMT1204M0-FM4 WMP20G performs best in stable toolholders with correct seating to preserve tolerance class and repeatability. For medium to heavy passes on stainless steel, the coated carbide grade maintains the cutting edge and helps control temperature-induced edge degradation. If process selection or parameter optimisation is required, Metav Werkzeuge provides technical advice and material-specific recommendations to align cutting data with machine capability and workpiece requirements; contact details are provided below for quick clarification.
