Higher process reliability when machining rostfreier Stahl

The combination of the WMP20G grade and Tiger·tec Gold technology is engineered to stabilise cutting edges under the thermal and mechanical loads typical for rostfreier Stahl. The coated cemented carbide substrate supports a controlled wear behaviour, which reduces the risk of built-up edge and enables repeatable surface finishes. With a negative 0° rake and a robust geometry, the insert maintains consistent engagement even in interrupted cuts, translating into fewer tool changes and more predictable cycle times for production runs.

Consistent chip control and extended edge life

An MM5 chipbreaker is integrated to direct chip flow and reduce entanglement in long turning operations. This chip geometry, together with the triangular 60° form, promotes short, manageable chips and lowers the thermal load on the cutting edge. The 0.8 mm corner radius supports durable edge strength, improving resistance to mechanical shock and increasing tool life in medium to heavy-duty turning. The technical design therefore enhances process security and reduces downtime for regrinding or replacement.

Efficient tooling and inventory management for workshops

The triangular insert offers three indexable cutting edges per insert, which improves material utilisation and reduces tooling costs per cutting edge. The standard designation TNMG160408-MM5 WMP20G makes tooling selection straightforward and compatible with common holder systems. As a Walter Tools product, the insert aligns with industrial expectations for consistent performance and predictable maintenance intervals, helping to simplify tooling logistics across batch production and job-shop environments.
