WNMG080412-RP5 WPP10G — Indexable turning insert, Trigon 80°, for Stahl (Walter Tools)

The WNMG080412-RP5 WPP10G is a trigon indexable insert engineered for high-productivity turning of Stahl, combining the Tiger·tec Gold coating and a robust geometry for reliable, repeatable performance.

• Tiger·tec Gold coated carbide for extended life
• Trigon 80° form for sturdy turning performance
• RP5 chipbreaker for consistent chip control
• 1.2 mm corner radius for improved edge stability

Maximise machining uptime with a wear-resistant grade

The combination of the Tiger·tec Gold coating and the WPP10G carbide grade delivers a measurable extension of tool life in typical turning operations on Stahl. The advanced multi-layer coating reduces flank wear and maintains cutting-edge integrity under thermal stress, which means fewer index changes and longer uninterrupted production runs. By choosing a coated grade that is optimised for heat and typical chip formation in Stahl, set-up frequency is lowered and overall machining efficiency improves.

Stable geometry for secure turning and predictable results

The Trigon 80° form and the 1.2 mm corner radius provide mechanical stability during cutting, reducing vibration and improving surface finish. The trigon shape offers three cutting corners per insert while a larger corner radius increases resistance to edge chipping when interrupted cuts occur. This results in more consistent dimensional accuracy and surface quality across batches, supporting tight tolerances and repeatable process capability on conventional and CNC lathes.

Effective chip control for safer, cleaner machining

The RP5 chipbreaker is designed to shape and break chips reliably when machining Stahl, improving evacuation and reducing risk of chip re-cutting. Controlled chip formation lowers the likelihood of tool damage and enhances operator safety. For processes where continuous chips can impede automation or affect coolant flow, a dedicated chipbreaker such as RP5 helps maintain stable cutting forces and contributes directly to predictable cycle times.

Integration and application guidance for production use

The insert is supplied in the WNMG format, compatible with standard toolholders for trigon inserts. With a negative rake angle of 0° and tolerance class M, it is suitable for general turning tasks in batch and serial production. The coated carbide construction and RP5 geometry make this insert particularly effective for medium to heavy finishing passes on Stahl where a balance of tool life and surface quality is required. When specifying cutter bodies and cutting parameters, select feeds and speeds that reflect the coated carbide’s strengths in heat resistance and wear behaviour for optimum results.
