CCMT120408-RM4 WMP30G turning insert by Walter Tools — Tiger·tec Gold, for stainless steel machining

A high-performance turning insert designed for stainless steel applications, combining the Tiger·tec Gold coating technology with the WMP30G grade for improved tool life and process stability

• Tiger·tec Gold coating for longer life
• WMP30G grade optimised for stainless steel
• Rhombus 80° insert form for versatile turning
• 0.8 mm corner radius for consistent finishes

Enhanced wear resistance for sustained productivity

The combination of Tiger·tec Gold coating and the WMP30G carbide grade provides improved wear resistance and stable cutting-edge performance when machining stainless steel. This coating technology reduces adhesive wear and supports secure chip formation under moderate to robust cutting conditions, which helps to maintain dimensional accuracy across longer tool life. For production environments where downtime and tool changes impact throughput, this insert offers a trustworthy balance between abrasion resistance and edge toughness. Explanations of technical terms: the coating forms a protective layer that reduces friction and heat at the cutting edge, while the grade controls substrate toughness to resist chipping.

Geometry and chip control that improve surface quality

The Rhombus 80° geometry combined with chipbreaker RM4 and a 0.8 mm corner radius delivers predictable chip formation and repeatable surface finishes. The 7° clearance angle reduces rubbing while preserving edge strength, so the insert supports both stable roughing cycles and fine finishing passes. For applications where stainless steels are prone to built-up edge and stringy chips, the RM4 chipbreaker contributes to reliable evacuation and smoother tool behaviour. The result is less rework and more consistent component quality in series production.

Practical advantages for workshop and production use

Built as a coated carbide turning insert, this CCMT variant is suitable for a wide range of turning tasks on stainless steel, from component repair to serial manufacturing. The insert's balanced properties aid machinists who require predictable tool life and consistent results across batches. Compatibility with standard CCMT toolholders simplifies tool changeovers and inventory management, enabling efficient workshop logistics. The product’s specification supports process reproducibility and helps reduce unexpected stoppages in machining cycles.
