CNMG120412-MU5 WPP20G indexable turning insert — Tiger·tec Gold coating, MU5 chipbreaker by Walter Tools (for steel)

A CNMG120412-MU5 WPP20G indexable turning insert engineered for productive steel machining, combining a coated carbide grade with a chipbreaker tuned to ISO P applications

• Tiger·tec Gold coating for high process security
• MU5 chipbreaker optimised for steel machining
• Rhombic 80° shape with 1.2 mm corner radius
• Negative 0° geometry for stable cutting

Greater wear resistance for predictable cycle times

The WPP20G grade uses the Tiger·tec Gold coating on a coated carbide substrate to provide reliable resistance against abrasive wear and thermally induced edge degradation. This results in longer tool life and fewer insert changes during batch production, which supports higher uptime and consistent output. Because the grade is tailored to ISO P materials, the insert is particularly suitable for a wide range of steel machining tasks, from general turning to semi-finishing, delivering a low-maintenance cutting solution that reduces process interruptions.

Reliable chip control and improved surface finish

The MU5 chipbreaker is designed to shape and evacuate chips effectively when machining steel, reducing the risk of re-cutting and chatter. Combined with the Rhombic 80° form and 1.2 mm corner radius, this geometry supports stable cutting forces and a controlled contact zone, so finished surfaces show improved consistency. The negative 0° relief provides a robust cutting edge that resists deflection under heavier cuts, which helps maintain dimensional accuracy and surface quality across component batches.

Machine-friendly design for repeatable performance

As an indexable insert, the geometry and tolerance class M support repeatable seating and simple clamping in standard toolholders. The CNMG form factor and the thickness code ensure predictable engagement with the workpiece and compatibility with common turning toolholders. With the combination of coated carbide performance and consistent indexability, the component contributes to process reliability and cost-effective productivity in workshop and production environments where steel is the primary work material.
