CNMM190624-HU5 WPP20G Walter Tools – Turning indexable insert with Tiger·tec Gold coating, for steel

CNMM190624-HU5 WPP20G is a precision turning indexable insert designed for productive machining of steel components, combining a coated carbide grade with a HU5 chipbreaker for controlled chip formation

• Tiger·tec Gold coated, wear-resistant grade WPP20G
• Designed for steel machining (ISO group P)
• Rhombic 80° insert with 2.4 mm corner radius
• HU5 chipbreaker for controlled chip formation

Extended process reliability through a modern coated grade

The Tiger·tec Gold coating and the WPP20G carbide formulation deliver high wear resistance and consistent edge stability during turning of steel. Engineered for the thermal and mechanical demands of ISO group P materials, this coated insert reduces flank and crater wear under typical turning conditions. The coated substrate supports longer cutting intervals, which can translate into increased uptime on production lines and fewer tool changes. As a result, cycle times remain predictable and tool consumption is optimised for economical batch production.

Robust geometry that prioritises cutting stability

The rhombic 80° shape combined with a 2.4 mm corner radius provides a strong cutting edge that tolerates interrupted cuts and heavy cuts with reliable performance. The insert’s 0° negative free angle reinforces edge strength and helps maintain dimensional stability during roughing operations. This geometry aids in distributing cutting forces across the insert, reducing the risk of premature edge chipping and supporting reproducible component tolerances in serial machining environments.

Controlled chip formation for improved surface quality

Equipped with the HU5 chipbreaker, the insert promotes predictable chip segmentation and efficient evacuation when machining steels. The designed chipflow reduces the risk of long, stringy chips that can interfere with toolpaths or workpiece integrity, and it contributes directly to a better surface finish on the turned component. Where surface integrity and consistent finishing are required, the controlled chip behaviour helps minimise rework and supports continuous manufacturing workflows.

Practical application notes and compatibility

The insert is specified as size 19 with thickness code 06, fitting standard toolholders that accept CNMM-style turning inserts. Classified for steels (ISO group P), it is suited to a range of turning tasks from medium-duty roughing to finishing where a balance between tool life and edge robustness is required. The WPP20G coated carbide is positioned as a versatile, wear-resistant grade for shop-floor conditions, enabling stable results across mixed batches of unalloyed and alloyed steels.

FAQ

What materials is the CNMM190624-HU5 WPP20G best suited for? The CNMM190624-HU5 WPP20G is optimised for steels (ISO group P), handling unalloyed and alloyed steels with controlled wear behaviour using the Tiger·tec Gold coated grade.

How does the HU5 chipbreaker benefit machining operations? The HU5 chipbreaker on this Walter Tools indexable insert promotes segmented chip formation and reliable evacuation, helping to improve surface finish and reduce downtime from problematic swarf.

Which cutting situations benefit most from the 2.4 mm corner radius? A 2.4 mm corner radius offers enhanced edge strength for both medium-duty roughing and finishing operations, improving resistance to chipping in interrupted cuts and maintaining dimensional stability.

Is the CNMM190624-HU5 suitable for heavy interrupted cuts? Yes, the rhombic 80° geometry and the 0° negative free angle provide a robust edge that tolerates interrupted cutting conditions, making it suitable for heavier engagements where edge security is essential.
