WNMG080412‑MW5 WMP20G — Trigon 80° turning insert, Tiger‑tec Gold (Walter Tools)

The WNMG080412‑MW5 WMP20G is a trigon 80° turning insert engineered for reliable machining of stainless steel under medium to robust cutting conditions

• Tiger‑tec Gold coating for enhanced wear resistance
• MW5 chipbreaker for stable chip control
• Trigon 80° geometry for secure clamping

Consistent results through optimised chip control and geometry

The combination of the MW5 chipbreaker and trigon form delivers stable chip control, reducing the risk of built-up edge and machine downtime when machining stainless steel. The insert’s design supports predictable chip forms even under interrupted cuts, which translates into fewer tool changes and more consistent parts per shift. This focus on process stability increases throughput without sacrificing component quality.

Extended tool life and surface quality from Tiger‑tec Gold

The Tiger‑tec Gold technology and coated‑carbide grade WMP20G provide improved wear resistance and thermal stability. Those properties help to maintain a sharper cutting edge for longer, which supports a steadier surface finish in serial production. In practice, the coating reduces flank wear and extends the interval between indexings, offering a measurable contribution to machining economy and reduced process variation.

Secure edge strength and clamping for heavy cuts

Trigon 80° geometry combined with a 1.2 mm corner radius and a 0° negative clearance ensures strong cutting edges and reliable clamping in robust operations. The insert’s shape improves cutting‑edge engagement and distributes cutting forces across a broader area, which is particularly beneficial when higher feed rates are required. The result is reduced vibration, fewer edge failures and a dependable platform for demanding turning tasks.

Application focus and process guidance

Designed primarily for stainless steel (material group M), this insert is intended for medium to robust conditions where secure chip evacuation and edge life are priorities. The coated carbide grade WMP20G is selected to counter the typical challenges of stainless steel machining — toughness, adhesion and heat generation — and to support predictable machining cycles. For process optimisation or insert selection across different stainless grades, technical consultation can help determine cutting data and toolholder combinations that maximise productivity.

FAQ

Which materials is this insert intended for? The WNMG080412‑MW5 WMP20G is specified for stainless steels (material group M), with the grade and coating tuned to cope with the toughness and adhesion tendencies of stainless steels.

What chip control can be expected with the MW5 chipbreaker? The MW5 chipbreaker on this insert promotes compact, controlled chips and reduces the likelihood of built‑up edge during turning with the WMP20G grade.

How does the trigon 80° geometry affect clamping and stability? Trigon 80° geometry provides a wide contact area for secure clamping; combined with a 1.2 mm corner radius and 0° negative clearance, it enhances edge strength and vibration resistance.

Is this insert suitable for finishing operations? The WMP20G grade and Tiger‑tec Gold coating favour robust and medium cutting conditions; while it supports good surface quality, process parameters should be adapted for fine finishing tasks.
