CCMT120408-RP4 WPP20G indexable insert — Tiger·tec Gold, for steel, Walter Tools

CCMT120408-RP4 WPP20G is an indexable cutting insert designed for drilling/boring and turning applications in steel, combining a coated-carbide grade with controlled chipbreaking for stable production results

• Tiger·tec Gold coating technology
• WPP20G grade for steel machining
• RP4 chipbreaker for stable chip control
• 7° relief and 0.8 mm corner radius

Consistent wear resistance for productive turning

The combination of the Tiger·tec Gold coating and the WPP20G grade delivers a balance of wear resistance and toughness tailored to ISO P materials (steel). This coated carbide formulation resists abrasive wear and thermal loads typical of steel turning, resulting in longer edge life and fewer insert changes. For production environments seeking improved tool life and predictable maintenance intervals, the grade’s engineered performance supports higher uptime and a more cost-efficient process.

Geometry that improves surface quality and reduces rework

The rhombic 80° seat and a 0.8 mm corner radius provide a reliable cutting geometry for finishing and semi-finishing passes. The RP4 chipbreaker produces controllable chip forms that lower the risk of entanglement and surface marks, while the 7° relief ensures stable engagement and predictable cutting forces. Together, these features reduce the need for corrective operations and help achieve consistent part tolerances in serial manufacture.

Versatile use and straightforward integration into tooling systems

With an inscribed circle of 12 mm and thickness code 04, this insert fits a broad range of standard toolholders for drilling/boring and external turning when the correct seat and clamping are used. Tolerance class M supports consistent seating and repeatability across inserts. Suitable for steel machining (ISO P), the insert is a practical choice for shops that demand versatility across component families. For application-specific advice on cutting data or holder selection, Metav Werkzeuge’s consultants can provide targeted recommendations.
