CNMG120412-MP5 WPP05G – Indexable turning insert, Tiger·tec Gold, Rhombic 80° (1.2 mm)

The CNMG120412-MP5 WPP05G is a rhombic 80° indexable turning insert designed for robust steel machining with a Tiger·tec Gold coated carbide grade

• Tiger·tec Gold coating for extended tool life
• MP5 chipbreaker for controlled chip formation
• 0° negative rake for stable heavy cuts
• 1.2 mm corner radius for consistent edge strength

Extended durability through advanced coating

The combination of a Tiger·tec Gold coated carbide grade and the WPP05G substrate delivers markedly improved resistance to abrasive and adhesive wear when machining steels. This coating technology is engineered to reduce flank wear and extend the interval between indexings, which translates into fewer tool changes and improved machine uptime. The coated carbide construction supports stable cutting temperatures and preserves the cutting edge under cyclical loading, providing a reliable basis for consistent production output.

Precise chip control and process stability

Equipped with the MP5 chipbreaker and a 0° negative rake, the insert is configured for dependable chip segmentation during a wide range of turning operations. This geometry reduces the risk of long or tangled chips on CNC lathes and enhances coolant access to the cutting zone, resulting in safer, more productive machining cycles. The controlled chip flow also helps maintain surface integrity and reduces the likelihood of workpiece damage, which supports higher first-pass yield rates in continuous production.

Geometry tuned for repeatable surface finish

The rhombic 80° form and a 1.2 mm corner radius combine to deliver a balance between edge strength and fine surface results. The insert geometry enables predictable tool engagement and a consistent cutting line, which assists in achieving dimensional accuracy and repeatable surface quality across batches. For operations where tool life and part finish must be balanced, this insert offers a clear advantage by reducing the trade-off between aggressive material removal and acceptable surface integrity.

Application guidance for efficient implementation

Designed primarily for steel (ISO P) applications, this insert is suited to unalloyed and alloyed steels where typical heat generation and chip formation patterns occur. The grade distribution within WPP05G favours a mix of wear resistance and toughness, supporting medium to high cutting speeds while maintaining a robust cutting edge. When integrating the insert into production, consider matching cutting parameters to material class and machine capability: the combination of the MP5 chipbreaker and the coated carbide grade performs best with stable machine setup, appropriate coolant strategy and moderate feed rates to exploit its wear-resistance without overloading the edge.
