VNMG160408-MK5 WKK10S – indexable turning insert for cast iron, Tiger‑tec Silver | Walter Tools

A VNMG160408-MK5 WKK10S indexable turning insert designed for robust performance when machining cast iron, offering high wear resistance and consistent short-chip behaviour for interrupted and continuous turning

• Tiger‑tec Silver coating for wear resistance
• WKK10S grade optimised for cast iron
• MK5 chipbreaker for controlled short chips
• Rhombic 35° shape, 0.8 mm corner radius

Productive machining of cast iron with extended edge life

The combination of the WKK10S coated carbide grade and the Tiger‑tec Silver technology yields a cutting edge engineered for abrasive conditions typical of cast iron. This results in improved wear resistance and a longer service interval between index changes, which supports a more continuous production flow. The coated grade is optimised for the short, brittle chips of cast materials and reduces flank wear under intermittent cuts, helping to sustain component tolerances and surface quality over longer runs.

Secure chip control and consistent surface finish

The integrated MK5 chipbreaker geometry promotes the formation of short, manageable chips even under interrupted cutting conditions. Combined with the Rhombic 35° geometry and a 0.8 mm corner radius, the insert provides a balance between stable cutting action and the ability to produce a reliable surface finish. The 0° negative rake increases edge robustness for heavy engagement, making the insert suitable where chip control and process security are priorities.

Optimal process stability for small and large batch production

Tolerance class M and the compact plate size support repeatable seating and low vibration across toolholders that accept VNMG formats. The insert’s construction and geometry contribute to predictable tool life and minimise unscheduled downtime, which in turn enhances overall shop productivity. The design is particularly advantageous for shops seeking a compromise between aggressive material removal and tool economy.

Material guidance and application notes for safe integration

Classified for ISO group K (cast iron), the grade is tailored to the abrasive wear and brittle chip characteristics of cast materials. The coated, wear‑resistant design is intended for stable cutting parameters rather than extreme high‑speed finishing, and it is well suited to typical cast iron turning tasks where short chips and controlled breaking are required. For tailored cutting data and holder compatibility, refer to tooling system documentation when integrating this insert into existing setups.

FAQ

Is this insert suitable for machining cast iron?
Yes. The insert is supplied in the WKK10S grade from the Tiger‑tec Silver series and is specifically optimised for ISO group K (cast iron) applications, where abrasive wear and short chips are common.

What does the MK5 chipbreaker deliver in practice?
The MK5 chipbreaker promotes short, well controlled chips, improving process stability and reducing the risk of entanglement during turning of brittle or interrupted cast iron sections.

How do the geometry and corner radius affect performance?
The Rhombic 35° geometry and 0.8 mm corner radius provide a compromise between a robust cutting edge and the ability to achieve consistent surface quality, while the 0° negative rake enhances edge strength for heavier cross‑sections.

Which series and coating technology is used for this insert?
The insert belongs to the Tiger‑tec Silver series with the WKK10S coated carbide grade, designed for high wear resistance and dependable performance in cast iron turning.
