CNMM160612-HU7 WPP20G indexable turning insert, Tiger·tec Gold — Walter Tools

The CNMM160612-HU7 WPP20G is a rhombic 80° indexable insert engineered for steel turning operations, combining a robust 1.2 mm corner radius with a Tiger·tec Gold coated carbide grade for extended wear resistance.

• Tiger·tec Gold coated carbide grade
• Rhombic 80° insert, 0° negative rake
• 1.2 mm corner radius for robust edge strength
• Optimised for steel machining (ISO P)

Longer life through advanced coating and grade

The Tiger·tec Gold technology used in this grade (WPP20G) provides a coated carbide formulation tuned for the thermal and tribological demands of steel cutting (ISO P). As a result, the insert delivers reduced flank wear and more consistent tool life under typical turning speeds, which translates into fewer tool changes and less machine downtime. The coated surface improves adhesion resistance and permits a broader range of cutting conditions while retaining predictable performance.

Reliable chip control and consistent surface quality

The integrated HU7 chipbreaker has been developed specifically for steel applications and promotes controlled chip formation across a wide range of feeds. Combined with the Rhombic 80° shape and 0° negative rake, this configuration offers stable cutting forces and improved process security during general turning and semi-finishing. The outcome is more repeatable part appearance and reduced risk of chip-related interruptions.

Stable edge and mechanical robustness for productive cutting

A 1.2 mm corner radius enhances edge strength and resistance to chipping, especially under interrupted cuts or moderate radial engagements. The insert dimensioning (16 mm nominal size, designation CNMM160612-HU7) and tolerance class M support precise seating in standard CNMM toolholders, ensuring accurate positioning and secure clamping. These mechanical attributes help maintain cutting stability, allowing higher metal removal rates without compromising component integrity.

Practical application and machining guidance

Designed primarily for steel, the grade distributes the balance between wear resistance and toughness to address both routine and demanding turning tasks. The coated indexable plate suits a range of operations from roughing to modest finishing when paired with appropriate feeds and cutting speeds. For specific cutting data, toolholder compatibility or optimisation strategies, Metav Werkzeuge provides application support and can advise on feed and speed windows aligned with the chosen machine and workpiece grade.
