CNMG190612-RM5 WSM20S indexable turning insert — Tiger‑tec Silver, for rostfreier Stahl and superalloys | Walter Tools

A CNMG190612-RM5 WSM20S is a rhombic 80° negative‑rake indexable insert designed for heavy and demanding turning tasks in rostfreier Stahl and heat‑resistant superalloys.

• Tiger‑tec Silver coating for high temperature stability
• Optimised RM5 chipbreaker for secure chip control
• Rhombic 80° form with 1.2 mm corner radius
• Negative 0° rake for heavy‑duty turning

Higher process reliability with material‑matched grade

The insert’s WSM20S grade, formulated within the Tiger‑tec Silver family, is engineered for turning of rostfreier Stahl and heat‑resistant superalloys. The coated carbide composition provides improved thermal resistance and stable wear behaviour that reduces the risk of edge build‑up when machining tough, heat‑sensitive materials. Practically, this means longer intervals between index changes and fewer unscheduled tool stops, which supports a steadier production flow and predictable component quality. The combination of coating and substrate enables consistent performance under elevated cutting temperatures.

Precise geometry for strong edges and consistent surface finish

This indexable cutting solution features an RM5 chipbreaker and a rhombic 80° seating that together deliver controlled chip formation and reliable cutting forces in heavier cuts. The 1.2 mm corner radius adds edge strength for interrupted cuts and roughing passes while still supporting acceptable surface quality for many finishing operations. The negative 0° rake contributes to tool stability and reduced vibration in robust machining scenarios. These geometric choices lower the likelihood of premature chipping and help maintain a predictable surface finish, which is particularly valuable in serial production and tight‑tolerance turning.

Practical benefits for workshop integration and productivity

Supplied in the common CNMG format, the insert fits widely used toolholders and can be integrated into existing turning programmes with minimal adjustment. The RM5 chip control reduces manual chip handling and supports uninterrupted operation on automatic lathes and CNC turning centres. By combining chip control, thermal robustness and a resilient cutting edge, the insert helps increase cutting parameters where admissible, improving throughput without compromising repeatability.

FAQ

Which materials is this insert best suited for?
The CNMG190612-RM5 WSM20S insert is optimised for rostfreier Stahl and for heat‑resistant superalloys and titanium alloys, offering thermal stability and secure chip formation for these demanding material classes.

What benefits does the Tiger‑tec Silver grade provide?
The Tiger‑tec Silver technology on the WSM20S grade improves thermal resistance and wear stability, which translates into longer tool life and more consistent component quality when machining tough, temperature‑sensitive materials.

When is the RM5 chipbreaker recommended?
The RM5 chipbreaker is designed for safe chip control in medium to heavy turning operations; it supports continuous chip evacuation and reduces interruptions in automated turning processes.

How does the 1.2 mm corner radius affect machining results?
A 1.2 mm radius increases edge robustness for interrupted cuts and higher feed rates, balancing edge strength with achievable surface finish for many semi‑finish and roughing tasks.
