TNMM220416-HU3 WPP20G turning insert (for steel) – Walter Tools

A TNMM220416-HU3 WPP20G triangular 60° turning insert engineered for stable chip control and extended tool life in general steel turning applications

• Tiger·tec Gold coated for extended tool life
• WPP20G grade, optimised for steel machining
• Triangle 60° insert with 1.6 mm corner radius
• HU3 chipbreaker for stable chip control

Higher productivity through consistent wear resistance

The combination of the Tiger·tec Gold coating and the WPP20G carbide grade is designed to provide consistent tool life when machining steels. The coating system reduces abrasive wear and improves thermal resistance, so cutting performance remains predictable over longer tool lives. This reliability translates into fewer insert changes, lower process interruptions and improved machine uptime. The result is an increase in overall machining productivity while maintaining repeatable dimensional and surface-quality outcomes.

Better surface finish and chip management for safer cycles

The HU3 chipbreaker together with the triangular 60° geometry and 1.6 mm corner radius is configured to produce controllable chip forms when turning unalloyed and alloyed steels. Stable chip formation lowers the risk of built-up edge and improves surface integrity, which reduces the need for secondary finishing operations. For operators and process planners, the improved chip flow simplifies handling and minimises downtime caused by chip-related disturbances, contributing to a safer and more efficient workshop environment.

Straightforward integration into standard toolholders

The ISO-style designation indicates compatibility with common clamping systems, which allows the insert to be used in many established turning toolholders without special adapters. The coated-carbide construction is suited to conventional cutting speeds for steel machining and is intended to balance toughness and wear resistance. Technical data such as geometry, negative relief angle and tolerance class support predictable set-up and repeatable results across series production runs, enabling process standardisation and simpler inventory management.

Application advice and practical support for process optimisation

For steel applications, the WPP20G grade is intended to address the typical heat and chip characteristics of this material group, offering a compromise between wear resistance and toughness. Cutting parameters should be selected according to the specific alloy and workpiece condition; when higher demands on tool life or finish are required, process trials under controlled conditions are recommended. If additional technical data or tailored cutting recommendations are needed, Metav Werkzeuge provides consultation and can supply recommended speeds, feeds and toolholder suggestions to match production goals.

FAQ

What materials is this insert suitable for?
The TNMM220416-HU3 WPP20G insert is specified for machining steels and the WPP20G grade is optimised for the thermal and chip-formation characteristics typical of that material group.

How does the HU3 chipbreaker affect machining?
The HU3 chipbreaker on this Walter Tools insert promotes controlled chip formation and evacuation, which enhances surface quality and reduces interruptions related to poor chip control.

What advantages does the Tiger·tec Gold series offer?
Tiger·tec Gold coating improves wear resistance and thermal stability, which helps to ensure consistent tool life and reliable performance in continuous turning operations.

Is the geometry compatible with common toolholders?
The ISO-style TNMM designation indicates compatibility with widely used toolholders for triangular 60° inserts, simplifying tool change and replacement.

What does the 1.6 mm corner radius mean for part quality?
A 1.6 mm corner radius balances edge strength and surface finish, providing robust cutting edges for general turning while maintaining good surface integrity.
