CNMM120412-HU5 WPP20G turning insert — rhombic 80°, 1.2 mm radius, for steel — Walter Tools

CNMM120412-HU5 WPP20G is a rhombic 80° turning insert designed for general steel machining where consistent performance and chip control are required, offered as a coated carbide grade in the Tiger‑tec Gold family.

• Tiger‑tec Gold coating for high productivity
• Optimised HU5 chipbreaker for controlled chips
• Rhombic 80° geometry with 1.2 mm corner radius

Efficient wear resistance for productive steel turning

The coated carbide WPP20G grade, part of the Tiger‑tec Gold series, is developed for demanding turning operations in steel. The multilayer coating increases abrasive wear resistance and thermal stability, which translates into longer edge life and fewer index changes in series production. For manufacturing environments that prioritise cycle time and uptime, the technical specification delivers measurable process security: consistent cutting performance, reduced tool-change frequency and reliable surface quality on each workpiece.

Geometry and chip management that stabilise the cut

The rhombic 80° insert shape combined with a 0° (negative) rake and the HU5 chipbreaker creates a controlled cutting zone that supports predictable chip formation and evacuation. The 1.2 mm corner radius provides a robust cutting edge able to withstand interrupted cuts and light roughing, while the chipbreaker design helps fragment swarf to avoid entanglement. For operators and process planners, this means fewer stoppages, improved turning stability and an easier set-up window when transferring parameters between machines.

Application advice and industrial suitability

Engineered primarily for steel (ISO material group P), this insert suits job shops and production lines that require reproducible results across a range of unalloyed and alloyed steels. The coated carbide grade offers a balance between wear resistance and toughness (10 wear‑resistant / 20 universal / 30–35 tougher zones in its application profile), making it versatile for finishing and light to medium roughing tasks. For selection support or parameter recommendations, in‑house technical advisors can provide cutting data adjusted to spindle speed, feed and depth of cut to help achieve the best life and surface finish.
