CCMT120412-RM4 WMP20G turning insert — rhombic 80° geometry, suitable for stainless steel — Walter Tools

The CCMT120412-RM4 WMP20G is a rhombic 80° turning insert designed for machining stainless steel in drilling, boring and general turning applications.

• Tiger·tec Gold coating for process stability
• WMP20G grade for stainless steel applications
• Rhombic 80° shape with 1.2 mm corner radius
• RM4 chipbreaker for controlled chips

Consistent chip control for stainless steel machining

The Tiger·tec Gold series and the WMP20G grade combine a coated carbide substrate with optimised surface engineering to reduce built-up edge and friction when cutting stainless steel. The result is stable chip formation and fewer interruptions for tool changes, which improves overall machine uptime. The RM4 chipbreaker is engineered to produce short, controllable chips in medium to robust cutting conditions, simplifying chip evacuation in deep grooves and interrupted cuts.

Geometry engineered for reliable cutting performance

A rhombic 80° insert geometry with a 7° relief angle and 1.2 mm corner radius delivers a balance between edge strength and accessibility. The geometry supports secure cutting in tough, work-hardened stainless steels by spreading cutting forces and reducing the risk of edge chipping. For operations that require both roughing and finishing, the shape and radius offer consistent surface quality while maintaining a robust cutting edge.

Productivity and tool-life benefits from coated carbide technology

The coated carbide construction of the Tiger·tec Gold family emphasises wear resistance and thermal stability under the high temperatures typical of machining stainless alloys. This leads to longer tool life and fewer indexings. For production environments where process reliability and repeatability matter, the combination of grade and coating provides a measurable reduction in downtime and rework, helping to maintain stable cycle times.
