Stable chip control for rostfreier Stahl with Tiger·tec Gold

The combination of the WMP20G substrate and the Tiger·tec Gold coating delivers consistent chip formation when machining rostfreier Stahl, a material group known for high toughness and tendency to form built-up edge. The integrated MU5 chipbreaker is optimised for medium to heavy engagement, reducing the risk of long, stringy chips and improving process reliability. By promoting secure breakage and preventing unstable cutting conditions, the insert supports predictable cycle times and fewer interruptions for clearing chips, which directly benefits throughput and shop-floor efficiency.

Geometry and edge design that increase tool life and security

Built on a DNMG150408-MU5 platform, the insert features a Rhombus 55° shape and a 0° (negative) free angle that prioritises robustness in interrupted or heavy cuts. The 0.8 mm corner radius and the 04 thickness provide a solid cutting edge that resists chipping and wear under higher mechanical loads. This geometry translates into a stable contact area, improved edge security and prolonged service intervals. For production environments where repeatability and predictable tool-change intervals matter, the insert’s shape and edge specification help to reduce unplanned downtime and maintain component quality.

Proven process security and straightforward integration in turning setups

Designed for ISO material group M, the insert is particularly suited to rostfreier Stahl applications where temperature and adhesion challenge conventional grades. Its standard DNMG form ensures compatibility with common tool holders, allowing fast replacement without complex adjustments. The coated carbide grade supports stable cutting edges and consistent surface finish across serial runs, which helps to lower scrap rates and improve first-pass yield. When combined with a controlled machining strategy, this insert contributes to measurable improvements in process reliability and overall cost-efficiency.

FAQ

What types of materials is this insert designed for?
The DNMG150408-MU5 WMP20G insert is optimised for rostfreier Stahl (ISO group M), providing good chip control and edge stability in demanding stainless applications.

Which chipbreaker and coating does the insert use?
This insert features the MU5 chipbreaker and the Tiger·tec Gold coating, delivering improved chip formation and enhanced resistance to built-up edge during turning.

What does the negative 0° free angle mean in practice?
A 0° (negative) free angle increases edge security and robustness; the insert therefore performs well in interrupted cuts or heavier machining passes where edge stability is critical.

Will the insert fit standard DNMG tool holders?
Yes, the DNMG format is a standard indexable insert form and the DNMG150408-MU5 WMP20G is compatible with holders designed for DNMG inserts, facilitating quick replacement.
