WNMG080412-MM5 WMP20G Turning Insert — Trigon 80°, 1.2 mm corner radius — Walter Tools

WNMG080412-MM5 WMP20G is a trigon-shaped turning insert engineered for medium to robust stainless-steel machining applications, offering a balance of edge strength and consistent chip control.

• Tiger·tec Gold coated carbide grade WMP20G
• Designed for stainless steel machining
• Trigon 80° shape for versatile turning
• 1.2 mm corner radius for robust edges

Improved process stability for stainless-steel turning

The combination of the Tiger·tec Gold coating and the WMP20G substrate supports secure chip formation when machining stainless steel, a material group known for toughness and a tendency to form built-up edge. The coating promotes heat resistance and wear control, which translates into more predictable tool life and fewer interruptions. For production environments where consistent component quality and reduced rework are priorities, this insert helps maintain cycle times by limiting unexpected edge failures.

Geometry tailored to robustness and versatility

The Trigon 80° shape with a 1.2 mm corner radius and a 0° (negative) rake angle increases edge strength and resistance to mechanical and thermal loads. The MM5 chipbreaker is designed to support stable chip detachment under medium to heavy conditions, reducing the likelihood of long, tangled chips and improving surface finish stability. These geometry choices make the insert suitable for interrupted cuts and heavier cross-sections where a strong cutting edge is essential.

Practical benefits and application guidance

The insert is specified for the ISO material group M, explicitly indicating suitability for stainless steel. In practice, this means safer cutting in jobs where toughness and heat generation are challenges. The product’s balanced design reduces downtime caused by tool changes and can improve overall productivity in batch production or mixed-lot machining. For tailored recommendations on feeds and speeds based on machine rigidity and component geometry, Metav Werkzeuge provides application support to optimise cutting parameters for the WNMG080412-MM5 WMP20G insert.

FAQ

What materials is this insert suitable for?
The WNMG080412-MM5 WMP20G insert from Walter Tools is specified for ISO group M and is suitable for machining stainless steel under medium to robust conditions.

How does the Tiger·tec Gold coating benefit machining?
Tiger·tec Gold on the WMP20G grade enhances wear resistance and heat management, improving tool life and process stability when turning demanding stainless-steel grades.

What are the advantages of the Trigon 80° shape and 1.2 mm radius?
The Trigon 80° geometry with a 1.2 mm corner radius delivers a robust cutting edge and versatile approach angles, supporting heavier cuts and better resistance to edge chipping in tougher turning tasks.

Is the MM5 chipbreaker suitable for finishing?
The MM5 chipbreaker is optimised for stable chip control in moderate to heavier cutting conditions; it provides improved chip form and surface consistency, particularly in semi-finishing and roughing operations on stainless steel.

Can this insert handle interrupted cuts?
Yes, the negative 0° relief and robust corner radius make the insert well suited to interrupted cutting and applications requiring enhanced edge strength.
