CNMM250924-HU7 WPP30G turning insert — Rhombic 80°, 2.4 mm corner radius — Walter Tools

CNMM250924-HU7 WPP30G is a coated carbide turning insert optimised for machining steel under the Tiger·tec Gold technology, providing a balance of wear resistance and toughness.

• Tiger·tec Gold coating for long tool life
• Optimised for ISO P (steel) machining
• HU7 chipbreaker for stable chip control
• Rhombic 80° form with 2.4 mm corner radius

Increase throughput with a wear-resistant grade

The combination of the WPP30G coating and a coated carbide substrate delivers a measurable improvement in tool life and consistency when machining steels classified under ISO group P. The Tiger·tec Gold technology is engineered to reduce flank wear and extend usable tool life, which contributes directly to lower tooling costs per component and fewer interruptions for indexable insert changes. As a consequence, cycle times remain predictable and machine utilisation improves, supporting continuous production runs in batch or single-part environments.

Stable chip flow and predictable process behaviour

The HU7 chipbreaker paired with a 0° negative relief angle produces controlled chip formation and evacuation, which reduces the risk of built-up edge and vibration in medium to heavy cutting conditions. This geometry helps maintain surface finish and dimensional stability over longer tool lives, making the insert well suited for medium machining and finishing of steel components. The predictable chip form simplifies coolant and chip conveyor setup and supports higher cutting parameters where process reliability is required.

Geometry tailored for repeatable precision

The rhombic 80° shape and 2.4 mm corner radius provide a robust cutting edge while allowing favourable approach angles for versatility across turning tasks. This geometry offers a balance between edge strength and accessibility for shoulder and profile turning, reducing the likelihood of premature chipping on interrupted cuts. The insert’s designation signals a standardised form factor that integrates smoothly into established tool holders and tool-setting processes, ensuring repeatable results part after part.

Practical application notes and integration into production

Designed primarily for steel machining, the grade is classified for the typical thermal and chip-formation characteristics of carbon and alloy steels. The insert’s tolerance class M and execution M indicate consistent dimensional accuracy suitable for production environments where interchangeability and minimal manual adjustment are essential. For optimal results, combine the insert with appropriate cutting data derived from material hardness, depth of cut and feed; the Tiger·tec Gold performance tends to be especially beneficial where a mix of wear resistance and fracture toughness is required.
