SNMG150616-MK5 WKK20S — indexable turning insert for cast iron, Tiger‑tec Silver, Walter Tools

A SNMG150616-MK5 WKK20S indexable turning insert designed for efficient machining of cast iron with a MK5 chipbreaker and a negative 0° rake for secure cutting action

• High wear resistance from Tiger‑tec Silver coating
• MK5 chipbreaker for controlled chip formation
• Square 90° geometry for versatile grooving and shoulder work
• Suitable for cast iron machining according to ISO classification

Increase throughput with a coating engineered for abrasive materials

The combination of the Tiger‑tec Silver coating and the WKK20S grade delivers enhanced resistance to abrasive wear, which directly translates into longer tool life and fewer tool changes during production. For operations on cast iron, this coated carbide formulation is adapted to the frequently short, brittle chip form typical of such alloys, enabling stable chip control and reduced downtime. The result is measurable productivity gains and lower process costs per part.

Secure cutting action and predictable edge performance

The MK5 chipbreaker and negative 0° rake produce a controlled cutting geometry that minimises vibration and promotes consistent cutting forces. With a square 90° shape and a corner radius of 1.6, the insert is well suited to finishing and semi‑finishing shoulders and faces where dimensional accuracy and repeatability are required. These design choices favour process reliability and make setup and parameter selection more straightforward for CNC turning operations.

Practical benefits for the workshop and production planners

Specifying this insert supports a rational machining strategy: fewer tool offsets, predictable tool life, and consistent surface finish for cast iron components. The insert’s tolerance class M and the Walter Tools series pedigree ensure compatibility with standard toolholders and ease of inventory management. For production planners, this translates into predictable maintenance cycles and improved overall equipment effectiveness (OEE), backed by the proven technology of Tiger‑tec Silver.
