Consistent performance and longer tool life with Tiger·tec Gold

The coated carbide grade in this series combines a wear-resistant substrate with the Tiger·tec Gold coating to deliver extended tool life under industrial turning conditions. The WPP20G grade is engineered for balanced toughness and wear resistance, which reduces the frequency of index changes and helps maintain consistent cycle times. As a result, process stability is improved and downtime for tool changes is reduced. The combination of a coated carbide substrate and an optimised surface finish on the insert flank contributes to reliable cutting edge behaviour at moderate cutting speeds.

Precise chip control and process reliability for Stahl

Equipped with the FP4 chipbreaker, this insert excels at controlling chip formation when machining Stahl. The chip geometry is shaped to break and evacuate efficiently, reducing the risk of built-up edge or entanglement in continuous turning operations. This targeted chip control supports safer, more predictable machining and helps achieve repeatable dimensional results. The insert’s features are specifically aligned to the thermal and material-removal characteristics of the P group, ensuring the grade addresses the typical heat and chip-formation challenges of Stahl.

Flexible geometry for a range of turning tasks and fine finishes

The rhombic 35° geometry provides a versatile cutting angle suitable for both roughing and light finishing passes, while the 0.4 mm corner radius helps produce consistent surface quality without compromising edge strength. A relief angle of 7° balances clearance with support behind the cutting edge, improving robustness during interrupted cuts. These geometry choices give machinists the option to use a single insert across multiple operations, simplifying inventory and setup.

Selection guidance and practical application notes

For demanding turning applications that require a balance of durability and surface integrity, the VCMT-style insert in the Tiger·tec Gold family represents a pragmatic choice. When choosing cutting parameters, prioritise stable feed rates and moderate speeds to exploit the coating’s wear resistance while maintaining chip-breaker effectiveness. If specific process data is needed—such as recommended speeds, feeds or machine-specific setup—technical consultation is available to ensure the grade and geometry align with the intended Stahl application and machining strategy.
