CNMG120412-MW5 WPP20G turning insert – Tiger·tec Gold, for steel | Walter Tools

The CNMG120412-MW5 WPP20G is a rhombic 80° indexable turning insert with a 0° negative rake, designed for reliable steel machining and versatile finishing and roughing operations.

• Tiger·tec Gold coated for high process reliability
• MW5 chipbreaker for stable chip control
• Rhombic 80° geometry with 0° negative rake
• 1.2 mm corner radius for consistent edge strength

Proven coating technology for extended tool life

The Tiger·tec Gold technology in this grade, WPP20G, is a coated carbide solution engineered for combination of wear resistance and toughness. This balanced performance yields longer intervals between indexings and fewer unplanned tool changes, which improves productivity and reduces operating cost per component. For metalcutting processes that generate heat and demanding chipformation, the coating supports process security through thermal stability and improved substrate protection, translating into consistent part quality over longer runs.

Geometry and chip control that protect the cutting edge

The insert’s chipbreaker MW5 is optimised to produce short, controllable chips across a wide range of cutting parameters, reducing the risk of chip entanglement and machine down-time. Combined with the rhombic 80° outline and 0° negative rake, the geometry provides a robust cutting position that resists edge damage while maintaining good accessibility for shoulder and profile turning. The 1.2 mm corner radius increases edge stability, which helps to preserve the cutting geometry during intermittent cuts and interrupted machining, so fewer insert changes are required in mixed production environments.

Clear material guidance and application focus

This grade is tailored to the steel (ISO P) group and is suitable for unalloyed and alloyed steels with typical heat and chip characteristics of such materials. The design emphasis on balance—wear resistance versus toughness—makes it a universal choice for a broad spectrum of steel turning tasks, from medium to heavy cuts as well as finishing passes where surface quality matters. Explaining ISO groups: ISO P denotes that the insert is intended primarily for steel machining, so toolpath strategies and cutting data should be selected with this material class in mind.

Practical process benefits and easy integration

As a standard CNMG-format insert with industry-recognised dimensions and clamping compatibility, this part integrates into existing toolholders without the need for special adapters. The combination of the Tiger·tec Gold coating and the MW5 chipbreaker supports higher cutting speeds and stable performance, which can shorten cycle times and increase throughput. For production planning, the predictable wear behaviour simplifies reconditioning and inventory planning, while the robust geometry reduces the likelihood of tool-related interruptions during shifts.
