TNMM220412-HU3 WPP20G turning indexable insert — Tiger·tec Gold grade for steel by Walter Tools

TNMM220412-HU3 WPP20G is a triangular turning insert engineered for efficient steel machining with a robust chipbreaker and a negative rake design

• Tiger·tec Gold coated carbide
• Optimised chip control HU3
• Triangle 60° shape for versatile turning

Improved process stability through a coated grade

The coated WPP20G grade from the Tiger·tec Gold series delivers consistent wear behaviour and stable cutting-edge performance in steel applications. The combination of a modern multi-layer coating and a wear-resistant substrate reduces flank and crater wear, resulting in longer tool life and fewer indexings. For production environments seeking predictable cycle times, this turning insert contributes to reduced unplanned downtime and improved overall equipment effectiveness.

Predictable chip formation for safer machining

The HU3 chipbreaker is specifically designed to produce short, controllable chips when cutting steels, which eases chip evacuation and minimises the risk of entanglement. The insert’s geometry — a triangle 60° form with a 1.2 mm corner radius and negative rake 0° — balances strength at the cutting edge with good access for finishing passes. This geometry ensures reliable surface results and reduces the likelihood of vibration-related defects in medium to heavy turning operations.

Flexible integration and handling advantages

As an indexable insert in the TNMM family, the plate offers four usable cutting edges, enabling economical use of the carbide blank before reconditioning or disposal. The standardised shape and size allow straightforward fitment in a wide range of turning tool holders, supporting quick changeovers on the shop floor. The tolerance class M and the plate’s design make it suitable for general turning tasks where robust performance and repeatability are required.

Clear application focus and machining guidance

Engineered for the ISO P group, this grade is optimised for a broad range of unalloyed and alloyed steel grades encountered in workshops and production lines. Speeds and feeds should be selected according to the specific steel grade and the machine’s rigidity; the coated carbide performs well at typical finishing and medium-cut conditions, improving surface quality without sacrificing tool life. The result is efficient material removal combined with a predictable tool consumption curve.
