TNMG160412‑MM5 WMP20G Drehwendeschneidplatte – Tiger·tec Gold for rostfreier Stahl (Walter Tools)

The TNMG160412‑MM5 WMP20G is a triangular indexable insert designed for turning rostfreier Stahl under medium to robust cutting conditions, offering secure chip control and a durable cutting edge.

• Tiger·tec Gold coating for extended life
• WMP20G grade for rostfreie Stähle
• MM5 chipbreaker for secure chip control
• Negative 0° rake for interrupted cuts

Consistent performance in rostfreier Stahl turning

The combination of the WMP20G cutting grade and the Tiger·tec Gold series is engineered for the specific demands of rostfreier Stahl, which typically produces tough, ductile chips and elevated temperatures during cutting. The coated carbide substrate and surface engineering support stable chip formation, reducing build‑up on the edge and keeping machining cycles consistent. This results in more predictable tool change intervals and less scrap from poor surface integrity, delivering measurable productivity improvements on stainless turning tasks.

Robust geometry for interrupted and heavy cuts

A negative 0° rake and the triangular 60° insert form give the insert a mechanically strong cutting edge that tolerates interrupted cuts and heavier feed rates without compromising edge stability. The corner radius 1.2 mm contributes to a balance between edge strength and surface finish; a larger radius improves edge life while maintaining acceptable component quality. The MM5 chipbreaker is optimised for secure chip control in demanding conditions, which lowers the risk of entanglement and supports automatic chip evacuation in production environments.

Economic benefits through longer tool life and process reliability

Using a coated carbide grade tailored to rostfreie Stähle ensures longer tool life and steadier cutting performance, translating into lower tool consumption and fewer unplanned stops. The insert's design supports predictable wear progression, enabling planned tool changes and improved machining throughput. For procurement and production planning, the clear specification of grade and geometry simplifies tool selection and reduces trial cycles, helping to keep machining costs under control without sacrificing part quality.

FAQ

What materials is this insert suitable for?
The TNMG160412‑MM5 WMP20G insert is specified for rostfreier Stahl and performs reliably under medium to robust cutting conditions.

How does the negative 0° rake affect machining?
A negative 0° rake strengthens the cutting edge for interrupted cuts and heavier feeds; the Walter Tools insert maintains edge stability while supporting consistent surface quality.

Which chip behaviour can be expected with the MM5 breaker?
The MM5 chipbreaker on this insert promotes secure chip formation and evacuation during rostfreier Stahl turning, reducing entanglement and improving process stability.

Can this insert be used for high‑speed finishing?
The WMP20G grade and Tiger·tec Gold coating are optimised for durability and chip control rather than ultra‑high‑speed finishing; consult Metav Werkzeuge for parameter tuning to balance speed and tool life.

What does the designation TNMG160412‑MM5 indicate?
The ISO code describes the insert geometry (triangular 60°), size (16 mm), corner radius (1.2 mm) and the fitted chipbreaker (MM5), enabling straightforward matching to appropriate tool holders.
