CNMG190616-RM5 WMP20G Turning Insert (Walter Tools) — 0° (negative), Rhombus 80°, for stainless steel

A CNMG190616-RM5 WMP20G turning insert engineered for secure chip formation and reliable edge stability in the machining of stainless steel components.

• Tiger·tec Gold coating for long tool life
• Optimised RM5 chipbreaker for stainless steel
• Rhombic 80° geometry for robust cutting
• 0° negative rake for secure clamping

Consistent chip control for demanding stainless-steel turning

The hardened composition and dedicated chip management deliver a measurable improvement in process stability when machining stainless steel. With the RM5 chipbreaker, chips are broken and evacuated reliably under medium to heavy cutting conditions, reducing the risk of built-up edge and improving surface quality. The insert’s behaviour is optimised for the thermal and work-hardening tendencies of austenitic and martensitic stainless steels, so operators see fewer interruptions and a steadier production flow.

Durable coating and geometry that extend tool life

The Tiger·tec Gold technology combines a coated carbide substrate with a surface architecture designed to resist abrasive and adhesive wear. This yields a stable cutting edge and extended tool life, which in turn increases uptime and lowers tooling costs per component. The grade WMP20G provides a balanced performance for medium to robust applications, supporting higher cutting speeds while maintaining dimensional consistency and repeatable finish quality.

Secure seating and robust shape for reliable turning operations

The rhombic 80° outline gives good access to a variety of cutting angles and supports stable insert clamping; combined with the 0° (negative) rake face the design reduces vibration and ensures dependable seat life in conventional toolholders. The defined corner radius 1.6 mm delivers a compromise between edge strength and achievable surface finish, making the insert suitable for both roughing and semi-finishing passes where edge robustness is required.

Practical integration into production for predictable results

Specified to common ISO geometry for indexable turning, this insert is straightforward to implement within existing tool systems and is particularly suited to workshops striving for consistent results under variable batch sizes. The combination of coated carbide, dedicated chip control and the insert’s geometry supports process reliability and helps to reduce scrap rates. For manufacturing environments where repeatability and predictable tool change intervals matter, the design contributes directly to overall productivity improvements.

FAQ

What materials is this insert suitable for?
The CNMG190616-RM5 WMP20G is designed primarily for machining stainless steel (material group M) and supports medium to robust cutting conditions.

What is the advantage of the RM5 chipbreaker?
The RM5 chipbreaker ensures reliable chip formation and evacuation when turning stainless steel, reducing built-up edge and stabilising machining processes.

How does the Tiger·tec Gold coating benefit cycle time?
The Tiger·tec Gold coating increases wear resistance and edge stability, which leads to longer tool life and fewer tool changes during production.

Which cutting tasks suit the rhombic 80° geometry?
The rhombic 80° shape provides robust cutting geometry for roughing and semi-finishing, offering good access to angled cuts and stable clamping.

What does the 0° (negative) free angle mean for clamping?
A 0° (negative) free angle improves clamping security and reduces vibration, helping to maintain consistent seat life under conventional toolholding conditions.
