CNMG120408-RP5 WPP20G — Indexable Turning Insert, Tiger·tec Gold, for Steel — Walter Tools

The CNMG120408-RP5 WPP20G is a rhombic 80° indexable turning insert designed for productive steel machining with a coated carbide grade optimised for stable chip formation and extended tool life.

• Tiger·tec Gold coated carbide
• RP5 chipbreaker for consistent chips
• Rhombic 80° geometry for versatility
• 0.8 mm corner radius for robust cutting

Proven coating technology for longer productive runs

The combination of the Tiger·tec Gold coating and a coated carbide substrate gives this indexable insert dependable wear resistance and stable edge life when machining steels classified under ISO P. The advanced coating reduces abrasive wear and supports consistent surface quality across medium- to high-volume turning operations, which lowers the frequency of tool changes and contributes directly to improved shop-floor efficiency. This technical pairing is particularly valuable in serial production where predictable performance reduces downtime and planning complexity.

Reliable chip formation and secure cutting performance

The RP5 chipbreaker has been engineered to create controllable chip shapes in a broad range of steel grades, improving swarf evacuation and minimising the risk of built-up edge. Together with the rhombic 80° shape and the negative 0° clearance, the insert offers a stable cutting geometry that enhances process reliability in both roughing and finishing passes. These design choices mean fewer interruptions for chip-related issues and more consistent part quality, translating into measurable gains in throughput.

Versatility tailored to steel applications

This cutting grade, WPP20G, is targeted at steel machining and covers a broad spectrum from wear-resistant to tougher steels. The combination of grade and geometry supports flexible use across different turning tasks, allowing a single insert type to address multiple components and reduce tooling complexity in the tool crib. The 0.8 mm corner radius provides extra edge strength for interrupted cuts while still permitting good surface finishes where required.

Practical handling and integration into production

The insert’s format, denoted CNMG120408-RP5, aligns with standard toolholders and clamping systems, simplifying inventory and setup. The nominal plate size and thickness are compatible with common toolpost and turret systems, while the tolerance class M ensures repeatable seating and stable run-out control. When combined with appropriate cutting parameters for ISO P materials, the insert contributes to reproducible cycle times and predictable tool-cost-per-part calculations.
