TNMM220408-HU3 WPP20G indexable turning insert — Walter Tools, Tiger·tec Gold, for steel machining

The TNMM220408-HU3 WPP20G is an indexable turning insert designed for productive machining of steel (ISO P), combining Tiger·tec Gold coating and the HU3 chipbreaker for consistent chip control in industrial turning applications

• Tiger·tec Gold coating for high wear resistance
• Grade WPP20G optimised for steel (ISO P)
• Triangular 60° form with 0.8 mm corner radius
• HU3 chipbreaker for stable chip control

Increased tool life and stable cutting performance

The advanced Tiger·tec Gold coating applied to this indexable insert significantly improves wear resistance and thermal stability compared with uncoated grades. The WPP20G grade is specified for machining steels and is balanced for wear resistance and toughness, which reduces flank and crater wear under typical turning conditions. As a result, tool changes become less frequent and process uptime increases, delivering tangible productivity improvements and lower total machining costs.

Geometry engineered for robustness and surface quality

The triangular 60° geometry with a 0.8 mm corner radius provides a robust cutting edge that withstands intermittent and heavier cuts. The insert’s 0° (negative) clearance ensures a secure seat in the toolholder and supports stable chip formation under higher radial loads. These geometric choices translate into better surface finishes and repeatable dimensional results, especially in serial production where consistent component quality is essential.

Chip control and material suitability for productive turning

The HU3 chipbreaker is tuned for steel applications and promotes short, segmented chips that evacuate reliably from the cutting zone. This reduces the risk of chip entanglement and secondary finishing operations. Classified for ISO group P (steel), the insert suits a wide range of unalloyed and alloyed steels, making it a versatile choice across many production tasks where predictable chip behaviour and tool life are required.

Practical benefits for workshop integration and handling

The triangular form provides three indexed cutting edges, improving economy per insert. The insert’s format and thickness code 04 facilitate rigid clamping in compatible toolholders, supporting stable cutting conditions. Specification and repeatability are supported by the Walter Tools manufacturing standard, which promotes consistent edge condition and minimal batch variation — important when integrating inserts into established production cycles or CNC tool lists.
