DNMG150602-FM5 WSM20S – Turning insert, Tiger·tec Silver, Walter Tools

The DNMG150602-FM5 WSM20S is a precision indexable turning insert designed for machining stainless steels and heat‑resistant superalloys, featuring a 0° negative rake and an FM5 chipbreaker for predictable chip control.

• Tiger·tec Silver coated carbide grade WSM20S
• Suitable for stainless steels and superalloys
• 0° negative rake for stable cutting
• Rhombic 55° form with 0.2 mm corner radius

Long‑term edge stability for demanding materials

The combination of Tiger·tec Silver coating and the WSM20S carbide grade provides high thermal resistance and stable cutting edges, reducing flank wear when turning tough alloys. Coating technology improves heat dissipation at the cutting zone and supports continuous production runs with fewer index changes. The insert’s design focuses on keeping the cutting edge intact under heavy thermal and mechanical loads, which translates into fewer unplanned tool changes and more consistent workpiece quality.

Predictable chip control and safer machining

Equipped with the FM5 chipbreaker, this insert promotes controlled chip formation even in materials that tend to form long, stringy chips. The chip control geometry reduces the risk of entanglement and supports reliable evacuation of swarf in automated and manual turning operations. As a result, cycle times remain stable and downstream processes are protected from irregular chip behaviour, contributing to a smoother production flow.

Precision geometry for repeatable results

The Rhombus 55° form combined with a 0.2 mm corner radius and 0° negative rake ensures a robust cutting edge that balances cutting forces and surface finish. The tolerance class M supports close dimensional repeatability in serial production. These geometric choices are aimed at achieving a compromise between edge strength and fine surface quality, making the insert suitable for shoulder cuts, finishing passes and moderate roughing where predictable performance is required.

Application focus: where the insert adds most value

This grade and geometry excel when machining stainless steels and heat‑resistant superalloys (ISO groups M and S). The coated carbide and chipbreaker are tuned to counter the typical challenges of these materials: poor heat conduction, work hardening and aggressive wear. In setups demanding process security and consistent tool life, the insert delivers a measurable improvement in repeatability and productivity compared with general‑purpose grades.

FAQ

What materials is this insert suitable for?
The DNMG150602-FM5 WSM20S insert is designed primarily for stainless steels (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), where the Tiger·tec Silver coating supports secure chip formation and thermal resistance.

How does the FM5 chipbreaker affect machining?
The FM5 chipbreaker on this turning insert produces controlled chips and reduces the risk of long, tangled swarf, improving process reliability and facilitating safer swarf evacuation in automated and manual turning applications.

Is the insert suitable for finishing operations?
Yes; the Rhombus 55° geometry with a 0.2 mm corner radius and 0° negative rake provides a balance between edge strength and surface quality, making it appropriate for finishing and light to moderate roughing tasks.

Which series and coating technology does this insert use?
This indexable insert belongs to the Tiger·tec Silver series and is supplied in the WSM20S coated carbide grade to enhance wear resistance and thermal stability during machining of tough alloys.
