WNMG080412-MP3 WPP30G indexable turning insert, Trigon 80°, for steel — Walter Tools

WNMG080412-MP3 WPP30G is a trigon-shaped indexable turning insert designed for robust steel machining applications, combining a coated carbide grade with an effective chipbreaker for consistent performance

• Tiger·tec Gold coating technology
• Optimised for steel machining (P)
• Trigon 80° insert form, 1.2 mm radius
• MP3 chipbreaker for reliable chip control

Consistent tool life through advanced coating and grade

The combination of the Tiger·tec Gold coating and the WPP30G carbide grade provides a balance of enhanced wear resistance and toughness that is particularly effective when machining steel. The coating reduces flank and crater wear under the thermal loads typical of steel turning, while the substrate composition supports stable cutting-edge behaviour. This results in durability and reduced frequency of insert changes, which supports higher overall machine utilisation and lower per-part tooling costs. The insert is produced to tolerance class M, ensuring consistent geometry for repeatable results in production environments.

Predictable chip formation and stable cutting geometry

The MP3 chipbreaker, combined with the Trigon 80° form and a 1.2 mm corner radius, is engineered to deliver controllable chip flow and secure edge strength for a wide range of turning tasks. A negative 0° rake configuration helps to strengthen the cutting edge under interrupted cuts and heavier depths of cut, while the chipbreaker promotes short, broken chips across typical steel grades. These features reduce the risk of chip entanglement and enable uninterrupted operation in automated setups. The insert’s geometry is therefore suitable where process reliability and clear swarf evacuation are required.

Application guidance and process relevance for production turning

Designed primarily for ISO P materials, the insert is suitable across the spectrum of steel machining needs, from more wear-resistant to tougher grades, as defined by the supplier’s classification. In practice, the component provides a reliable compromise between abrasion resistance and fracture toughness, allowing machinists to maintain steady metal removal rates without excessive edge chipping. The trigon shape gives versatility for various turning operations, including profiling and light shoulder work. For tailored cutting data or to confirm suitability for a specific steel grade, process consultation is available to help integrate the insert into existing turning cycles.
