TNMM160408-HU3 WPP20G indexable turning insert – for steel (Tiger‑tec Gold) | Walter Tools

The TNMM160408-HU3 WPP20G is a triangular 60° indexable turning insert with a Tiger‑tec Gold coated grade, engineered for efficient, high‑productivity turning of steel components.

Tiger‑tec Gold coating for extended tool life
WPP20G grade optimised for steel machining
Triangle 60° plate with 0.8 mm corner radius
HU3 chipbreaker for reliable chip control

High productivity through advanced coating and grade

The combination of the Tiger‑tec Gold coating and the WPP20G grade delivers a balanced performance profile tailored to steel turning. The coated carbide substrate provides improved wear resistance and heat management compared with uncoated grades, which translates into longer tool life and fewer indexings during production. This makes the insert particularly suitable for medium‑ to high‑volume machining where consistent cutting performance and reduced tool costs are priorities. The design reduces unscheduled downtime and supports steady output in a production environment.

Geometry and chip control for consistent surface finish

The triangular 60° plate form with a 0.8 mm corner radius and the HU3 chipbreaker create a robust cutting edge that tolerates interrupted cuts and varying engagement conditions. The 0° (negative) relief configuration contributes to a stable cutting geometry, while the chipbreaker optimises chip formation for typical steel alloys. Together these features help to maintain dimensional accuracy and surface quality during sustained turning operations, offering predictable results on turned parts where repeatability is essential.

Application range and process benefits

Designed for the ISO P material group, this insert is intended specifically for turning steel, including both unalloyed and alloyed grades. The WPP20G sort is aimed at a versatile balance between wear resistance and toughness, providing reliable performance across common steel machining tasks. For manufacturers and job shops seeking an economical, reproducible solution, the insert supports efficient cycle times and simplified tool management thanks to its standardised geometry and Walter Tools quality.

FAQ

What materials is this insert suitable for?
The TNMM160408-HU3 WPP20G insert is specified for the ISO P material group and is optimised for turning various types of steel.

How does the Tiger‑tec Gold coating benefit production?
The Tiger‑tec Gold coating on the WPP20G grade enhances wear resistance and thermal stability, which helps extend tool life and supports continuous production with fewer indexings.

What does the HU3 chipbreaker do?
The HU3 chipbreaker is designed to control chip formation in steel turning, improving evacuation and reducing the likelihood of built‑up edge, which contributes to consistent surface finishes.

Is the insert suitable for interrupted cuts?
Yes, the triangle 60° geometry combined with the 0° (negative) relief and robust grade makes the insert well suited to conditions that include interrupted cutting.

How to identify the correct designation for ordering?
Order using the full designation TNMM160408-HU3 WPP20G (Walter Tools) to ensure the correct insert geometry, grade and chipbreaker are supplied.
