Higher process stability through controlled chip formation

The combination of the HU5 chipbreaker and the Tiger‑tec Gold coated carbide grade WPP20G delivers consistently shaped chips during conventional and interrupted cuts. This reduces the risk of built‑up edge and tool chatter, which in turn supports predictable cycle times and reduces scrap rates. The insert’s negative rake of 0° (negative) promotes increased edge strength, making the geometry particularly suitable for robust turning tasks where tool integrity is paramount. Explaining the technicalities: the coating reduces friction at the cutting zone and enhances wear resistance, while the chipbreaker geometry shapes the flow of material, improving evacuation and surface finish on steel.

Geometry engineered for repeatable accuracy and surface quality

The rhombic 80° form and the 1.6 mm corner radius provide a good balance between cutting edge strength and surface finish. The insert’s form factor supports axial and radial engagements common in a wide range of turning operations, enabling predictable contact conditions and reduced deflection. With tolerance class M, the insert meets industrial repeatability demands, contributing to consistent component roundness and dimension control. The profile also facilitates indexability and fast edge changes, keeping machine downtime to a minimum and supporting tight production schedules.

Productivity advantages for serial production

As a coated carbide solution, the grade emphasises long tool life and broad applicability across unalloyed and alloyed steels. The WPP20G grade within the Tiger‑tec Gold family targets general steel machining with improved wear resistance and stable edge behaviour; the result is fewer tool changes and a lower cost per part. In practice, stations that switch to this insert observe less process variation and improved throughput. The product’s build supports industrial users seeking efficiency gains without sacrificing surface integrity or increasing inspection workload.

FAQ

What materials is this insert suitable for?
The CNMM190616‑HU5 WPP20G turning insert by Walter Tools is optimised for machining steel (P) and is designed to handle the heat and chip formation typical for that material group.

How does the Tiger‑tec Gold coating benefit production?
The Tiger‑tec Gold coating on the WPP20G grade reduces friction and improves wear resistance, which increases tool life and supports consistent performance across production runs.

What does the HU5 chipbreaker deliver in practice?
The HU5 chipbreaker provides stable chip formation and reliable evacuation, improving surface finish and reducing the likelihood of chip‑related interruptions during turning.

Is the negative rake angle important for heavy cuts?
Yes, the 0° (negative) free angle increases edge robustness and helps maintain tool integrity in heavy cuts and interrupted machining, contributing to process security.

Can this insert be used for finishing and roughing?
With a 1.6 mm corner radius and rhombic profile, the insert is versatile enough for both stable roughing operations and productive finishing when parameters are adjusted accordingly.
