VNMG160404-MM5 WMP20G turning indexable insert for stainless steel, Tiger·tec Gold — Walter Tools

The VNMG160404-MM5 WMP20G is a rhombic 35° turning indexable insert engineered for machining stainless steel under moderate to robust conditions, offering controlled chip formation and long edge life.

• Tiger·tec Gold coated carbide grade WMP20G
• Optimised chip control with MM5 breaker
• Rhombic 35° shape for versatile turning
• 0.4 mm corner radius for stable edge

Precise chip control for stainless steel turning

The WMP20G grade, implemented in the Tiger·tec Gold series, is a coated carbide solution optimised for stainless steel. The combination of coating technology and the MM5 chipbreaker promotes consistent chip formation and evacuation, reducing the risk of built-up edge. This leads to fewer interruptions and more stable cycle times. For operators unfamiliar with chipbreaker terminology: the chipbreaker is a surface geometry that controls chip flow and reduces thermal load at the cutting edge, which helps to maintain surface quality and dimensional stability.

Robust edge strength and consistent tool life

A 0° negative rake delivers mechanical strength at the cutting edge, making the insert resilient during interrupted cuts and heavier cross-sections. The 0.4 mm corner radius balances edge durability with the ability to achieve acceptable surface finishes; larger radii increase edge strength, while smaller radii favour finer finishes. The rhombic 35° shape provides a versatile entering angle for general turning operations, enabling secure clamping in standard holders and repeatable performance across diverse parts. These design choices contribute to predictable tool life and process security in series production.

Integration into production and practical notes

With a nominal size of 16 mm and a thickness of 4 mm, the insert is compatible with conventional VNMG holders and indexing systems, facilitating quick tool changes and minimal setup time. The ISO designation VNMG160404-MM5 WMP20G standardises tooling selection and helps with inventory management. For machining strategies, the insert is especially suited to medium to heavy operations on stainless steel, where controlled chip breaking and edge stability are priorities.
