CNMG120412-RM5 WMP30G indexable turning insert — Tiger·tec Gold, for stainless steels (Walter Tools)

The CNMG120412-RM5 WMP30G is a rhombic 80° indexable turning insert designed for consistent, productive machining of stainless steels in medium to robust conditions.

• Tiger·tec Gold coating for edge stability
• Optimised chip control RM5 geometry
• Rhombic 80° with 1.2 mm corner radius
• Negative 0° rake for secure cutting

Improved process reliability through advanced grade technology

The CNMG120412-RM5 WMP30G insert combines the Tiger·tec Gold technology with a coated carbide substrate to address the typical challenges of machining stainless steels: toughness, tendency to form built-up edge and heat generation. The result is a more stable cutting edge and predictable tool life under medium to robust cutting conditions. The coated grade supports secure chip formation and reduces the frequency of insert changes, contributing to a smoother production flow and fewer unplanned interruptions.

Consistent chip control and surface finish for dependable results

Built-in RM5 chip control geometry enables reliable evacuation of chips and reduces risk of tangling or surface impairment. The insert geometry — rhombic 80° combined with a 1.2 mm corner radius — balances strength and versatility: the radius provides a robust cutting edge for interrupted cuts while still enabling acceptable surface finishes. The negative 0° rake promotes secure cutting forces and helps maintain dimensional accuracy when turning tougher stainless variants, supporting reproducible component quality.

Practical integration and material compatibility in the workshop

This indexable insert is intended for turning applications on stainless steels, as classified for ISO group M, where secure chip control and edge life are priorities. Compatibility with standard CNMG toolholders and the common 12-size format simplifies tool inventory and replacement. The RM5 chipbreaker reduces secondary operations by improving chip flow and minimising edge build-up, while the coated grade reduces sensitivity to transient temperature spikes during production runs. For workshops aiming to raise throughput without sacrificing reliability, the combination of grade and geometry supports measurable process improvements.
