CNMM190624‑HU3 WPP20G Turning indexable insert — Tiger‑tec Gold for steel, Walter Tools

CNMM190624‑HU3 WPP20G is a turning indexable insert engineered for productive steel machining, featuring Tiger‑tec Gold coating and an HU3 chipbreaker for controlled chip formation

• Tiger‑tec Gold coated carbide grade WPP20G
• Optimised HU3 chipbreaker for steel
• Rhombic 80° insert shape
• 2.4 mm corner radius for stable cutting

Boosted productivity through tailored coating and grade selection

The combination of the Tiger‑tec Gold coating and the WPP20G carbide composition is designed to increase machining efficiency when turning steels. The coating reduces flank and crater wear, so tool change intervals are extended and cycle times can be reduced without sacrificing process reliability. For the production environment, this means fewer interruptions and a higher throughput per tool life. The insert’s performance is particularly evident in medium to high cutting speeds where coating technology contributes to thermal stability and consistent edge life.

Consistent chip control and surface quality from the geometry

The rhombic 80° shape paired with the HU3 chipbreaker enables well‑formed chips and dependable evacuation in typical steel applications. A 2.4 mm corner radius provides a larger contact area, which stabilises the cut and helps to damp vibrations, improving surface finish and dimensional accuracy. The negative 0° free angle increases robustness for interrupted cuts and heavy‑duty turning tasks, so the insert withstands tougher engagement conditions while maintaining acceptable roughness values on the workpiece.

Clear application range and simplified process planning

This insert is classified for the ISO P group and is suited to a broad spectrum of steels, from high wear‑resistant to universal grades; the grade balance supports both productivity and tool life. The marked subdivision of the sort (10 wear‑resistant; 20 universal; 30/35 tougher) assists process engineers in selecting cutting data and feeds that match production aims. Selection is facilitated by the standardised CNMM190624‑HU3 designation, which aligns with established toolholder systems and reduces complexity in tooling logistics for batch production.

Reliability, repeatability and brand assurance

Designed by Walter Tools within the Tiger‑tec Gold family, the insert supports stable cutting edge behaviour and predictable performance in serial manufacturing. The robust construction and coating technology allow for repeatable results across shifts, aiding quality control and reducing rework rates. This combination of process certainty and tried‑and‑tested coating technology contributes to lower total tooling costs per produced component and a more efficient production flow.
