WNMG080408‑MU5 WMP20G indexable turning insert for stainless steel, Tiger·tec Gold — Walter Tools

The WNMG080408‑MU5 WMP20G is an indexable turning insert with Trigon 80° geometry, engineered for reliable machining of stainless steel under moderate to robust conditions.

• Tiger·tec Gold coated carbide grade WMP20G
• Optimised for stainless steel (ISO M)
• Trigon 80° geometry, 0.8 mm corner radius
• MU5 chipbreaker for stable chip formation

Consistent cutting performance that raises throughput

The Tiger·tec Gold grade WMP20G provides a balance between wear resistance and edge toughness, tailored for the demands of stainless steel turning. The combination of the coated carbide substrate and an optimised surface finish enables improved heat management and reduced tendency for built-up edge, which translates into fewer tool changes and higher machine uptime. This results in tangible production advantages: more consistent component quality and predictable machining cycles thanks to controlled flank wear and secure chip formation.

Robust geometry that protects the cutting edge and reduces rework

The Trigon 80° form with a corner radius of 0.8 mm and a negative rake of 0° is designed for stability during interrupted cuts and heavier feed conditions. A negative rake increases edge strength and supports repeatable performance in tougher turning operations, while the MU5 chipbreaker promotes short, manageable chips, lowering the risk of surface damage and machine downtime. These features together help to reduce rework rates and improve overall process reliability on demanding materials.

Practical integration and application advice for the workshop

As an indexable insert intended for ISO group M, this grade is suited to operations where secure chip control and edge life are priorities rather than ultra-high-speed finishing. Typical applications include medium-duty external turning and facing of austenitic and other stainless alloys. When introducing the insert into a tool system, select a compatible holder that supports the Trigon 80° form and verify clamping rigidity; modest increases in coolant or careful selection of cutting parameters often extend tool life. For tailored recommendations on cutting data or holder compatibility, expert consultation is available to facilitate efficient process adoption.
