CCMT120408-RM4 WMP20G indexable insert (Tiger·tec Gold) by Walter Tools — rhombic 80°, RM4 chipbreaker

CCMT120408-RM4 WMP20G is a coated carbide indexable insert designed for turning applications on stainless steel under medium to robust cutting conditions

• Tiger·tec Gold coating for stable cutting
• Optimised RM4 chipbreaker for stainless steel
• Rhombic 80° shape for versatile turning
• 7° relief angle with 0.8 mm corner radius

Reliable chip control for consistent productivity

The combination of the Tiger·tec Gold coating and WMP20G grade provides a balanced hardness and toughness that promotes stable chip formation when machining stainless steel. The integrated RM4 chipbreaker is tailored to break and evacuate chips reliably under varying feed rates, which reduces the risk of built-up edge and contributes to repeatable process windows. This results in fewer interruptions for manual chip clearing and a smoother production flow, making the insert especially suitable for series turning where consistency and minimised downtime are priorities.

Durable edge and process security for demanding operations

A coated carbide substrate in the WMP20G class supports a stable cutting edge across longer tool lives, improving overall process security. The coating technology of the series enhances thermal resistance and wear behaviour in the face of high friction typical of stainless steel machining. As a consequence, tool-change intervals become more predictable and the operation benefits from better surface finish and dimensional repeatability. These factors combine to increase net productivity and make the insert a cost-effective option in medium to robust applications.

Geometry that supports versatility and precise turning results

The rhombic 80° form with a 7° relief provides a good balance between accessibility and strength of the cutting edge, while the 0.8 mm corner radius offers a compromise between edge strength and achievable surface finish. The insert’s dimensions and clamping compatibility allow integration into standard turning toolholders for facing, profiling and general external turning tasks. For process planning, consider stable clamping and consistent coolant strategy to maintain the advantageous cutting conditions that this insert is designed to deliver.
