WNMG080404-MP5 WNMG080404-MP5 WPP20G Indexable turning insert for Stahl (Tiger·tec Gold) — Walter Tools

WNMG080404-MP5 WPP20G is an indexable turning insert designed for general steel applications, offering a balance of wear resistance and toughness for productive turning operations

• Tiger·tec Gold coating for extended tool life
• MP5 chipbreaker optimised for Stahl machining
• Trigon 80° form for heavy-duty turning
• Negative 0° rake with 0.4 mm corner radius

Higher throughput from advanced coating and geometry

The combination of the Tiger·tec Gold coating and the engineered geometry delivers measurable gains in tool life and process reliability. The coated carbide grade WPP20G is formulated to resist abrasion while maintaining edge stability, which reduces the frequency of index changes and interruptions. With its MP5 chipbreaker, this insert shapes chips predictably during common turning cycles in Stahl, helping to avoid entanglement and maintain consistent cutting forces. The result is a smoother production flow and fewer unplanned stoppages.

Stable cutting performance for demanding turning tasks

Designed as a Trigon 80° insert with a negative 0° relief, this grade provides a robust cutting edge that tolerates higher radial engagement and interrupted cuts. The moderate 0.4 mm corner radius aids edge strength for roughing and medium finishing without compromising surface integrity. For applications where reliability and repeatable results matter, the insert’s geometry and coating work together to ensure steady behaviour under load, improving cycle predictability and reducing scrap rates.

Practical selection and application guidance for machinists

Selecting this insert supports versatile use across a broad range of steels as defined for material group P. The MP5 chipbreaker is optimised for general turning, offering a compromise between chip control and surface finish. When used with appropriate feeds and depths of cut for the workpiece and machine rigidity, the grade enables efficient metal removal while maintaining acceptable tool life. Where coolant is applicable, its use can further stabilise temperatures and prolong edge life; for dry machining, monitoring tool wear and adjusting parameters will preserve component quality.

FAQ

What materials is this insert suited for?
The WNMG080404-MP5 WPP20G is intended for machining Stahl (material group P) and performs across a wide range of unalloyed and alloyed steels.

How does the Tiger·tec Gold coating benefit the cutting process?
The Tiger·tec Gold coating on the WPP20G grade increases wear resistance and edge stability, which helps the Walter Tools insert maintain consistent performance and longer life in demanding turning operations.

What is the purpose of the MP5 chipbreaker?
The MP5 chipbreaker is designed to produce manageable chips and stable cutting forces during turning of Stahl, improving chip evacuation and reducing the risk of built-up edge.

Is the Trigon 80° form suitable for interrupted cuts?
Yes, the Trigon 80° geometry combined with a negative 0° relief offers robustness and improved resistance to shock, making the insert suitable for operations with occasional interruptions.

Which corner radius is recommended for mixed roughing and finishing?
The 0.4 mm corner radius on this insert balances edge strength with surface quality, making it a practical choice for mixed roughing and semi-finishing tasks.
