WNMG080408-MP3 WPP20G turning insert — Trigon 80°, Tiger·tec Gold coating, Walter Tools

WNMG080408-MP3 WPP20G is an indexable turning insert designed for machining steel with a Trigon 80° form and a negative 0° rake angle

• Trigon 80° geometry for stable turning
• Tiger·tec Gold coating for extended life
• MP3 chipbreaker for controlled chip formation
• Negative 0° rake, 0.8 mm corner radius

Higher throughput through coating and chip control

The combination of the Tiger·tec Gold coating and the MP3 chipbreaker delivers improved tool life and consistent chip formation when machining ISO P materials (steel). The advanced coating reduces flank wear under typical steel cutting temperatures, which translates into longer operational intervals between index changes and fewer unplanned stoppages. As an indexable insert, this item is intended for series production where repeatability and predictable wear behaviour are decisive for process planning and cost control.

Stable geometry for precise turning and surface quality

A Trigon 80° shape with a 0.8 mm corner radius and a negative 0° rake provides mechanical strength at the cutting edge and resistance to edge chipping during interrupted cuts. This geometry supports stable cutting forces and helps maintain dimensional accuracy on shafts and turned faces. The tougher corner form is especially beneficial for medium to heavy turning operations where tool robustness outweighs the need for the finest possible nose radii.

Practical benefits for shop-floor productivity

Using the WPP20G grade means a balanced hardmetal substrate and coating designed for a broad range of steels, offering a compromise between wear resistance and toughness. The result is predictable performance across different steel grades and milling conditions, helping to reduce tooling variants in stock. The insert’s chip control and edge integrity contribute to fewer reworks and a more consistent process capability, supporting lean manufacturing targets and better utilisation of machine time.

Application guidance and selection hints

This turning insert is suited to general turning tasks on steel components, from roughing to medium finishing, and is particularly effective where robust edge stability is required. Selection should consider matching insert geometry and chipbreaker to the part application: the MP3 breaker is optimised for controlled chip segmentation in steels, while the Trigon 80° profile gives added edge strength for interrupted cuts.

FAQ

What materials is this insert intended for?
The insert is designed primarily for ISO P materials; the WPP20G grade from Walter Tools is optimised for machining steel.

How does the Tiger·tec Gold coating affect tool life?
The Tiger·tec Gold coating improves wear resistance and thermal stability, which typically extends the productive life of the insert under steel turning conditions.

What advantages does the Trigon 80° form provide?
Trigon 80° geometry offers increased corner strength and resistance to edge breakage, making it suitable for interrupted cuts and heavier turning operations.

Which chipbreaker should be selected for controlled chips?
The MP3 chipbreaker on this insert is tuned for reliable chip formation in steels and supports safe evacuation in both continuous and interrupted cuts.

Is this insert suitable for finishing operations?
The insert can be used for medium finishing; however, final surface requirement and part tolerances should guide the selection of nose radius and cutting parameters
