CNMG190612-RM5 WSM30S indexable turning insert — Tiger·tec Silver coating, for stainless steel & superalloys | Walter Tools

A CNMG190612-RM5 WSM30S indexable turning insert engineered for machining stainless steel and heat-resistant superalloys with secure chip control and long tool life

• Tiger·tec Silver coated for edge life
• RM5 chipbreaker for stable chip control
• Rhombic 80° shape for versatile turning
• 0° negative rake for tough materials

Reliable performance on stainless steel and superalloys

The WSM30S grade is a coated carbide solution developed for demanding materials. Its Tiger·tec Silver coating combines wear resistance with thermal stability, supporting machining of stainless steel (ISO group M) and heat-resistant superalloys and titanium (ISO group S). This composition reduces the tendency for built-up edge and supports a consistent cutting process, which is particularly valuable in serial production where repeatable surface quality and predictable insert life are required.

Geometry and chip control that improve process stability

Rhombic 80° form and the RM5 chipbreaker work together to deliver controlled chips and secure cutting even at higher feeds. The insert’s 1.2 mm corner radius stabilises the cutting edge for small interrupted cuts and helps achieve improved surface integrity. With a 0° negative rake, the geometry prioritises edge robustness and resistance to thermal and mechanical loading, making it suitable for heavy cuts and the poorer heat conductivity typical of superalloys.

Productivity gains and cost-effective usage

Using a grade optimised for these materials yields longer tool life and fewer changeovers, which translates into improved cycle times and lower overall machining costs. The insert’s tolerance class M and the standard CNMG shank compatibility ensure predictable seating and repeatability across toolholders. By selecting a grade tailored to the workpiece group, process windows broaden and cutting data become more reliable, enabling higher metal removal rates without compromising surface finish.

Practical integration and machining advice

This indexable turning insert fits standard CNMG toolholders and is intended for secure clamping with the correct seat and screw. For best outcomes, pair the insert with stable tooling and suitable coolant strategies when machining heat-prone materials. The combination of Tiger·tec Silver technology and the RM5 chipbreaker simplifies the transition from trial to production, helping to maintain consistent part quality and reducing unscheduled downtime.
