WNMG080412-MP5 WPP20G – Trigon 80° turning insert with Tiger·tec Gold coating (Walter Tools)

The WNMG080412-MP5 WPP20G is a trigon 80° turning insert designed for productive steel machining, offering a coated carbide grade optimised for predictable wear behaviour and wide material coverage.

• Tiger·tec Gold coated grade WPP20G
• Trigon 80° form for stable cutting
• MP5 chipbreaker for predictable chips
• 0° negative rake, 1.2 mm corner radius

Higher productivity through optimised grade and coating

The combination of Tiger·tec Gold coating and the WPP20G carbide grade delivers a balance of wear resistance and toughness tailored for steel machining. The coating reduces flank wear and thermal load during interrupted cuts, while the substrate provides toughness where chip formation is critical. For manufacturing environments seeking reduced downtime, this insert enables longer tool life and more consistent cycle times, turning the material class P (steel) into a repeatable process step with fewer interruptions.

Consistent chip control and surface finish

The MP5 chipbreaker and Trigon 80° geometry work together to produce controllable chip forms and stable cutting forces. The moderately large corner radius of 1.2 mm supports a robust cutting edge and improves surface integrity at finishing and semi-finishing depths. For those less familiar with tool geometry: the trigon shape provides three effective cutting corners per indexable insert, increasing tool utilisation and reducing changeover frequency while maintaining a predictable contact geometry for consistent part quality.

Process security and application guidance for production

Designed for a broad range within steel machining, the insert supports medium to heavy turning operations where reliable edge life and steady cutting forces are required. The 0° negative rake enhances edge stability on roughing passes and under interrupted cutting conditions, while the product family’s specifications align with common ISO P classifications. If clarification is needed on machining parameters or clamping recommendations, Metav Werkzeuge offers application assistance to match speeds, feeds and insert clamping to the specific machine and workpiece setup.

FAQ

What materials is this insert suitable for?
The WNMG080412-MP5 WPP20G insert is specified for steel applications (ISO group P) and is optimised to handle the heat and chip characteristics typical of unalloyed and alloyed steels.

How does the Tiger·tec Gold coating help performance?
The Tiger·tec Gold coating on the WPP20G grade reduces flank wear and improves thermal resistance, which helps the insert maintain cutting edge integrity and consistent tool life under production conditions.

Is the insert available in other corner radii or geometries?
This SKU is the Trigon 80° form with a 1.2 mm corner radius; Walter Tools offers other geometries and radii in the same family for different turning strategies and edge-strength requirements.

What cutting scenarios suit the 0° negative rake?
The 0° negative rake is advantageous for interrupted cuts and roughing operations where edge strength and stability are prioritised over minimal cutting forces.

Can the MP5 chipbreaker be used for finishing passes?
The MP5 chipbreaker is designed for predictable chip control across a range of depths of cut; it supports semi-finishing and certain finishing strategies where stable chip evacuation is required.
