SNMG120412‑MP3 WPP20G Turning indexable insert — Tiger·tec Gold, universal for Stahl — Walter Tools

The SNMG120412‑MP3 WPP20G is a square 90° indexable insert designed for general turning applications in Stahl, combining a wear-resistant Tiger·tec Gold coating with an MP3 chipbreaker for reliable chip control in continuous and interrupted cuts.

Tiger·tec Gold coating for long tool life
Universal WPP20G grade for Stahl
MP3 chipbreaker for consistent chip control
1.2 mm corner radius for robust cutting edge

Higher throughput on Stahl thanks to optimised coating and grade

The combination of the Tiger·tec Gold coating and the WPP20G grade delivers an excellent balance between wear resistance and toughness, which translates into longer service life and fewer index changes. Designed for the machining of Stahl according to ISO 513 group P, this insert supports typical heat and chip formation encountered during turning, so that cycle times can be reduced while maintaining dimensional stability. The grade’s universal character makes it suitable for a wide range of unalloyed and alloyed steels, enabling tool inventories to be simplified without sacrificing process reliability.

Safer cutting, controlled chips and robust edge security

Built with the MP3 chipbreaker and a 1.2 mm corner radius, the insert offers predictable chip formation and a sturdy cutting edge that tolerates moderate interruptions and edge wear. The 0° (negativ) relief angle increases mechanical strength at the cutting edge, which is particularly useful for heavier cuts or interrupted operations. Explained simply, the negative rake increases edge robustness at the cost of slightly higher cutting forces — a trade-off that benefits stability and repeatable surface finish in demanding production environments.

Efficient integration on the shop floor and consistent quality

The square 90° geometry and the SNMG designation provide four usable cutting corners per insert, improving cost-efficiency in serial production. Manufactured to tolerance class M, the insert ensures repeatable seating and axial runout when used with compatible toolholders. Selection of the SNMG120412‑MP3 WPP20G reduces setup variability and supports predictable tool-change intervals, contributing to leaner process flows and lower per-part tooling cost. For applications requiring guidance on toolholder pairing or cutting parameters, Metav Werkzeuge offers technical consultation to match the insert to the specific machining task.
