TNMM160412-HU3 WPP20G Turning indexable insert — Tiger·tec Gold, for steel (Walter Tools)

TNMM160412-HU3 WPP20G is an indexable turning insert designed for efficient steel turning, delivering reliable wear resistance and consistent chip control in general machining applications.

Tiger·tec Gold coating for high wear resistance
Designed for steel machining (ISO P)
HU3 chipbreaker for controlled chip formation
Triangle 60° form with 1.2 mm corner radius

Longer tool life through advanced coating technology

The insert’s Tiger·tec Gold grade WPP20G combines a hard, wear-resistant coating with a tough substrate to extend tool life during continuous steel turning. This formulation is optimised for the heat and chip shapes typical of ISO P materials, so the result is a reduced rate of flank wear and fewer tool changes. The outcome for production is greater uptime and lower tool consumption per component, which improves process economics without sacrificing finish.

Stable chip control and improved surface finish

The HU3 chipbreaker is engineered to produce predictable chips that evacuate cleanly from the cut, reducing the risk of entanglement and tool damage. The controlled chip formation contributes directly to a better surface quality and more stable cutting forces, which supports higher material removal rates under correct cutting conditions. For operations where part finish and dimensional consistency matter, this geometry helps maintain repeatable results over longer tool life.

Geometry designed for robust turning and versatility

A triangle 60° insert form offers multiple indexable cutting corners and a compact cutting edge for robust engagement in interrupted or continuous cuts. The 1.2 mm corner radius balances edge strength with the capacity to achieve fine surface finishes; a larger radius would increase robustness but could compromise fine finishing, while a smaller radius would be more fragile. The insert’s 0° negative clearance provides a stable cutting edge orientation for heavier cuts and reliable seat in standard TNMM toolholders.

Practical benefits for workshop integration

Marked as TNMM160412-HU3 WPP20G, the insert fits TNMM-compatible holders and is straightforward to replace and index, supporting quick changeovers. Its specification and ISO designation simplify procurement and inventory management across production lines. Given its focus on steel machining, this insert suits mixed-production environments seeking a universal grade that handles a broad range of unalloyed and alloyed steels while keeping processes predictable and efficient.
