TNMG220408-MP3 WPP20G — indexable turning insert, Tiger·tec Gold, for steel by Walter Tools

TNMG220408-MP3 WPP20G is a triangular 60° indexable insert designed for productive turning of steel under demanding industrial conditions

• Tiger·tec Gold coating for longer tool life
• MP3 chipbreaker optimised for steel turning
• 60° triangular geometry for stable turning
• 0.8 mm corner radius for improved surface finish

Productivity gains for steel machining

The combination of the Tiger·tec Gold coating and the WPP20G cutting grade delivers a measurable increase in tool life and process stability when machining steels (material group P). The coated carbide composition resists abrasive and adhesive wear, which keeps cutting parameters stable for longer running times. With the MP3 chipbreaker, chip formation is adapted to typical steel cutting conditions, reducing interruptions caused by poor chip control and enabling higher metal removal rates without compromising component tolerances.

Controlled chips and consistent surface quality

The MP3 chip control geometry is designed to produce short, manageable chips in a wide range of steels, improving both safety and machining continuity. The triangular 60° form provides three cutting edges per insert, supporting economical use and quick indexing. A 0.8 mm corner radius gives a balance between edge strength and surface finish, making the insert suitable for light finishing as well as heavier roughing cuts where edge security is required. The negative 0° relief angle contributes to a more rigid cutting edge under heavy loads.

Seamless integration into turning operations

With a tolerance class M and industry-standard designation, this indexable insert is compatible with common clamping systems and toolholders for TNMG-style inserts. The geometry and coating are optimised for stable chip formation and repeatable performance across shift changes, which supports predictable cycle times and easier process planning. The coated carbide grade and the Tiger·tec Gold lineage ensure the insert is a practical choice where process reliability and consistent component quality are priorities, particularly in serial production of steel parts.

FAQ

What steels is this insert suitable for?
The TNMG220408-MP3 WPP20G is specified for machining steels (material group P) and is optimised for the heat and chip formation characteristics typical of unalloyed and alloyed steels.

What does the MP3 chipbreaker achieve in practice?
The MP3 chipbreaker on this insert promotes short, controlled chips when turning steel, improving process continuity and reducing the risk of entanglement or machine stoppages.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating enhances wear resistance and edge stability, which translates into longer tool life and more consistent machining results with the WPP20G grade.

Is the 0.8 mm corner radius suitable for finishing?
A 0.8 mm corner radius offers a compromise between edge strength and surface finish; it is suitable for semi-finishing and finishing operations where a robust edge is required.

Can this insert be used with standard TNMG holders?
The insert follows the TNMG designation and tolerance class M, making it compatible with standard TNMG-style toolholders; holder selection should match the negative 0° relief and application requirements.
