TNMG160408-RP5 WPP20G indexable turning insert, Tiger·tec Gold, for steel — Walter Tools

The TNMG160408-RP5 WPP20G is a triangular 60° indexable insert designed for demanding steel turning, offering a coated carbide grade that balances wear resistance and toughness.

• Tiger·tec Gold coated carbide grade WPP20G
• RP5 chipbreaker for reliable chip control
• Triangular 60° shape with 0.8 mm nose radius
• Optimised for steel machining (ISO P)

High productivity through a balanced carbide grade and coating

The combination of Tiger·tec Gold coating and the WPP20G grade provides a balanced performance profile: enhanced wear resistance combined with sufficient toughness for varied cutting conditions. This coated carbide system reduces flank wear and extends tool life under typical steel turning heat and stress, which translates into longer uninterrupted production runs and fewer insert changes. The result is predictable tool behaviour that supports process planning and reduces unexpected downtime.

Reliable chip control for safer, cleaner operations

The RP5 chipbreaker is engineered to produce short, consistent chips when machining steels, improving evacuation and reducing the risk of entanglement. Effective chip control reduces secondary operations and cleaning time, while improving surface consistency on the workpiece. For less experienced operators, the defined chip formation simplifies process setup and reduces the need for repeated parameter adjustments.

Geometry that supports precision and versatility

The triangular 60° plate form with a 0.8 mm nose radius offers a practical compromise between strength and finish capability. The insert’s 0° (negative) clearance provides a stable cutting edge under heavier cuts and interrupted cuts, enhancing edge security and repeatability. These geometric choices allow for both roughing passes at higher material removal rates and fine finishing passes that achieve consistent surface quality.

Application-oriented performance and process security

Specifically developed for ISO group P (steel) applications, this insert suits a broad range of unalloyed and alloyed steels. The design emphasis is on maintaining a steady cutting edge and predictable tool life, supporting efficient batch production and one-off jobs alike. The engineered balance of wear resistance and toughness means fewer unexpected insert failures and a more economical overall machining process. The insert’s compatibility with common toolholders makes integration into existing turning stations straightforward.
