VCMT160404-RM4 / VCMT160404-RM4 WMP20G / WMP20G — Turning insert for stainless steel · Walter Tools

A VCMT160404-RM4 WMP20G turning insert designed for dependable performance in stainless steel machining under medium to robust cutting conditions.

• Tiger·tec Gold coated carbide grade WMP20G
• Optimised RM4 chipbreaker for stable chips
• Rhombic 35° VCMT form with 0.4 mm radius
• Specifically for stainless steel machining

Higher productivity through tailored coating and chip control

The combination of the Tiger·tec Gold coating and the WMP20G grade provides enhanced wear resistance and thermal stability, which translates into longer cutting intervals and fewer tool changes. The RM4 chipbreaker is developed to promote controlled chip formation when machining stainless steel, reducing the risk of built-up edge and improving process stability. These technological choices aim to increase net machining time and reduce overall production cost per component, making the insert suitable for series production and demanding one-off work alike.

Geometry that supports consistent surface quality and tool life

The rhombic 35° form with a 0.4 mm corner radius and a 7° relief angle delivers a balanced compromise between accessibility and edge strength. This geometry permits close approach to shoulders and fine finishing while maintaining a robust edge for interrupted cuts. The insert’s consistent profile helps produce repeatable surface finishes and makes toolpath planning more predictable—advantages that are particularly valuable when machining tough, work-hardening stainless materials where stability at the cutting edge directly affects component quality.

Application-focused benefits for shop-floor integration

With its VCMT160404-RM4 designation the insert fits standard toolholders and is straightforward to introduce into existing processes. The coated hardmetal substrate supports higher cutting speeds and contributes to quieter cutting behaviour and reliable edge retention. For operations seeking improved throughput, this insert supports shorter downtime and simplified inventory management due to its broad applicability for stainless steels. If specific cutting data or optimisation help is required, Metav Werkzeuge provides technical consultation to align cutting parameters, workholding and coolant strategy with the chosen grade and chipbreaker.
