DNMG110412-RP5 WPP20G rhombic 55° turning insert for steel — Walter Tools

The DNMG110412-RP5 WPP20G is a rhombic 55° indexable turning insert engineered for steel machining, featuring a Tiger·tec Gold coated carbide grade and an RP5 chipbreaker for stable cutting.

• Tiger·tec Gold coating for long tool life
• Designed for steel machining (ISO group P)
• RP5 chipbreaker for reliable chip control
• 1.2 mm corner radius, rhombic 55° geometry

Higher output through a wear-resistant coating

The Tiger·tec Gold WPP20G grade combines a modern coated carbide structure with optimised microgeometry to extend edge life under demanding conditions. This results in fewer insert changes and longer uninterrupted runs on production lathes, which directly improves machine uptime and lowers tooling costs per part. The coating is tuned for the heat and chip characteristics typical of steel machining, so the grade provides predictable wear and helps maintain dimensional consistency across batches.

Precise chip control and consistent surface quality

Equipped with an RP5 chipbreaker and a rhombic 55° form, the insert ensures controlled chip formation and evacuation during both medium and finishing passes. The combination of chip geometry and a 1.2 mm corner radius reduces vibration and produces stable cutting forces, delivering improved surface finish and repeatability. For operators unfamiliar with chipbreaker types: RP5 is designed for segmented chips and stable evacuation, reducing the risk of re-cutting and tool interference.

Robust geometry suited to general turning operations

The negative rake angle of 0° (negative) provides a robust cutting edge that tolerates interrupted cuts and variable feed rates often encountered in shop-floor turning. The rhombic 55° configuration offers versatile approach angles for external turning and profile work, allowing the same insert to be used across several turning tasks without frequent tool changes. This flexibility supports shorter set-up times and simpler tool management in mixed-production environments.

Seamless integration and application benefits

Classified for ISO group P (steel), the insert integrates with standard DNMG toolholders and is suitable for a wide range of unalloyed and alloyed steels. The M tolerance class and the established Tiger·tec Gold series promise repeatable mounting and consistent cutting geometry, which simplifies process parameter transfer between machines. In short runs and volume production alike, the combination of grade, chipbreaker and geometry delivers a balance of productivity and surface integrity for commercial turning operations.
