WNMG080408-MM5 WMP30G – Trigon 80° indexable turning insert, Tiger‑tec Gold (Walter Tools)

The WNMG080408-MM5 WMP30G is an indexable turning insert engineered for machining stainless steels under medium to robust cutting conditions, optimised for stable chip formation and consistent edge life.

• Tiger‑tec Gold coated carbide grade WMP30G
• For machining stainless steels (ISO group M)
• Trigon 80° geometry for robust turning
• 0.8 mm corner radius, negative 0° rake

High performance for stainless steel turning with consistent chip control

The Tiger‑tec Gold coating and coated carbide grade WMP30G deliver a combination of wear resistance and thermal stability that addresses the specific challenges of stainless steels: toughness, built‑up edge tendency and elevated cutting temperatures. The insert’s chipbreaker and coating work together to enable stable chip formation, reducing interruptions due to irregular chips and helping to maintain an even machining rhythm. This results in fewer unplanned index changes and improved process reliability for series production.

Geometry designed to withstand robust cuts and secure edge strength

The Trigon 80° shape provides a robust nose and broad support for the cutting edge, while the 0.8 mm corner radius increases edge strength for interrupted or heavier cuts. The negative 0° rake enhances edge security and reduces the risk of edge chipping when working with difficult stainless alloys. Together with the MM5 chipbreaker, the geometry supports consistent surface quality and tool life in demanding turning operations.

Productivity gains through reduced downtime and repeatable performance

Selecting this grade and geometry aims to lower overall machining cost per part by extending the interval between index changes and maintaining dimensional stability. The combination of coating, grade and chip control contributes to productive machining and fewer scrap parts, especially in batch or continuous runs. The tolerance class and stable cutting edge support repeatable results across tool changes, helping to keep setups predictable and cycle times steady.

Practical application and handling advice for workshop integration

This indexable insert is intended for standard toolholders designed for WNMG inserts and is simple to rotate or replace when the cutting edge reaches wear limits. For optimal results with the WNMG080408‑MM5 WMP30G insert, ensure rigid clamping of the toolholder and consistent cooling strategy adapted to the stainless alloy in use. The insert’s layout supports quick indexing to a fresh edge and straightforward integration into existing turning processes from Walter Tools.

FAQ

Is this insert suitable for a wide range of stainless steels?
Yes. The WNMG080408‑MM5 WMP30G insert is designed for stainless steels (ISO group M) and supports medium to robust cutting conditions with stable chip formation.

What role does the MM5 chipbreaker play?
The MM5 chipbreaker promotes controlled chip formation and evacuation, improving surface quality and reducing the risk of entangling chips during turning with the WMP30G grade.

How does the Trigon 80° geometry affect machining?
The Trigon 80° shape offers a robust nose and greater edge support, which enhances resistance to mechanical shock and helps maintain dimensional stability in tougher turning operations.

Is the negative 0° rake beneficial for interrupted cuts?
Yes. The negative 0° rake increases edge security and reduces the chance of chipping under interrupted or heavier cutting conditions when using this Walter Tools insert.

Can the insert be used with standard WNMG toolholders?
The insert is an indexable-type suitable for standard toolholders designed for WNMG geometry; replacement or indexing provides access to a fresh cutting edge when required.
