CCMT120408-MW4 WPP20G turning indexable insert by Walter Tools — Tiger‑tec Gold, MW4 chipbreaker

The CCMT120408-MW4 WPP20G is a rhombic 80° turning insert designed for efficient steel machining with a Tiger‑tec Gold coated carbide grade and a controlled-chip MW4 land.

• Tiger‑tec Gold coated carbide grade WPP20G
• MW4 chipbreaker for secure chip control
• Rhombic 80° geometry for versatile turning
• 7° clearance and 0.8 mm corner radius

Higher productivity through robust grade and coating

The combination of the WPP20G grade and Tiger‑tec Gold coating provides improved wear resistance and a consistent cutting edge suited to general steel turning. The coated carbide structure reduces flank wear and supports longer tool life, which translates into fewer tool changes and less downtime on production lines. For manufacturers focused on throughput, this insert delivers a balance of performance and economy by maintaining cutting stability across a variety of unalloyed and alloyed steels defined under ISO group P.

Predictable finishes and secure chip control for process reliability

The insert’s MW4 chipbreaker and rhombic 80° form are engineered for controlled chip formation during medium to heavy cuts. A 7° relief angle combined with a 0.8 mm corner radius stabilises the cutting edge, improving surface finish and dimensional repeatability on turned parts. These geometry choices reduce the likelihood of unexpected tool failures and help maintain machining parameters over longer runs. For toolroom planners and shopfloor engineers, the result is reliable cycle times and improved component quality.

Clear application focus and straightforward tooling decisions

This grade and geometry are optimised for machining steel (ISO P), offering a versatile solution for a broad range of turning tasks without needing multiple special-purpose grades. The insert’s coated carbide construction supports standard coolant conditions and offers predictable regrinding or replacement intervals. If additional technical details or cutting-parameter guidelines are required for specific steels or inserts holders, Metav Werkzeuge can provide application recommendations and machining data to support process setup.
