SNMG120408-MM5 WMP20G turning insert — Tiger·tec Gold coating for rostfreier Stahl, Walter Tools

The SNMG120408-MM5 WMP20G is a square 90° indexable turning insert designed for medium to robust machining of rostfreier Stahl, offering a combination of a coated carbide grade and a dedicated MM5 chipbreaker for secure chip control.

• Tiger·tec Gold coated carbide, grade WMP20G
• Optimised for rostfreier Stahl machining
• Square 90° form with 0.8 mm corner radius
• 0° negative rake with MM5 chipbreaker

Longer service life through advanced coating technology

The insert uses the Tiger·tec Gold coating system on a WMP20G coated carbide substrate, engineered to resist work-hardening and maintain a stable cutting edge under the thermal and mechanical stresses typical of rostfreier Stahl machining. The coated surface reduces flank wear and supports heat dissipation, which translates into fewer indexings and extended tool life. In production terms, this means improved process economy and less downtime for tool changes, while preserving dimensional stability of turned components.

Reliable chip control and consistent surface finish

With the MM5 chipbreaker and a square 90° format, the geometry promotes predictable chip formation and evacuation when facing and light turning stainless steels. The 0.8 mm corner radius balances edge strength and finish capability, reducing edge chipping while enabling acceptable surface finishes without aggressive feed rates. The 0° negative rake provides a secure cutting edge for interrupted cuts or harder zones in rostfreier Stahl, improving operational reliability in mixed-production environments.

Seamless integration into production workflows

The insert’s familiar SNMG format simplifies toolholder selection and inventory management across turning lines. Coated carbide and the Tiger·tec Gold technology support higher cutting parameters compared with uncoated grades, which can shorten cycle times and improve throughput. Where consistent part quality is a priority, this insert contributes to reproducible results and stable process windows, making it suitable for batch production and job-shop settings that demand predictable performance.

FAQ

What materials is this insert suitable for?
The SNMG120408-MM5 WMP20G is specified for rostfreier Stahl and is engineered to handle the toughness and heat generation typical of stainless steels.

How does the Tiger·tec Gold coating benefit performance?
The Tiger·tec Gold coating on the WMP20G grade enhances wear resistance and thermal stability, which supports longer edge life and more consistent component quality during stainless steel turning.

Which chipbreaker is fitted and what is its role?
The insert features the MM5 chipbreaker, designed to promote controlled chip formation and reliable evacuation in a range of turning conditions.

Is the insert suitable for interrupted cuts?
Yes; the 0° negative rake and robust grade make the insert well suited to interrupted cutting and mixed-condition turning where edge security is important.

How should toolholders be selected for this insert?
Standard SNMG-compatible toolholders with appropriate clamping for square 90° inserts are recommended; ensure holder geometry supports the 0° relief and desired cutting parameters.
