CNMG120408-MP5 WPP30G — Indexable turning insert, Tiger·tec Gold coating for steel (Walter Tools)

The CNMG120408-MP5 WPP30G is a rhombic 80° indexable insert engineered for efficient turning of steel components in production and jobbing environments.

• Tiger·tec Gold coated for high productivity
• MP5 chipbreaker for reliable chip control
• Rhombic 80° geometry for flexible turning
• 0.8 mm nose radius for consistent surface finish

Optimised productivity and process security with coated carbide

The combination of the Tiger·tec Gold coating and the coated carbide substrate provides a reliable balance between wear resistance and toughness, which leads to longer tool life under typical steel cutting conditions. This geometry and grade are specifically designed to manage the heat and chip formation that occur when machining steel; the result is improved cycle times and fewer interruptions for tool changes. The rhombic 80° form allows adaptable entry and exit angles in turning operations, while the MP5 chipbreaker optimises chip flow for automated and manual setups. Such characteristics contribute directly to stable machining behaviour and predictable performance.

Consistent surface finish and secure chip control

A 0.8 mm nose radius combined with the MP5 chipbreaker delivers a balance between edge strength and surface integrity. The moderate radius produces reliable component finishes without compromising the cutting edge under interrupted cuts or heavier feed rates. At the same time, the chip geometry promoted by the chipbreaker reduces the risk of entanglement and improves evacuation in both conventional and high-feed turning. For operations where repeatability and surface quality matter, the described insert minimises rework and supports consistent part acceptance criteria.

Versatility for steel applications and straightforward tool management

Classified for steel (ISO group P), this grade is intended for a broad range of steels from general-purpose to tougher, wear-prone materials. The insert’s tolerance class M and robust grade designation support repeatable indexing and predictable tool life across batch production. The rhombic 80° shape and standard size facilitate integration into common toolholders, simplifying inventory and tool change procedures. Together, these attributes reduce tooling complexity on the shop floor while maintaining a high level of process reliability and productivity.
