VNMG160404-MK5 WKK10S indexable turning insert — Rhombus 35°, Tiger‑tec Silver (Walter Tools)

A VNMG160404-MK5 WKK10S indexable turning insert engineered for productive cast iron machining, featuring a 0° negative rake and MK5 chip control for repeatable results.

• Tiger‑tec Silver coating for wear resistance
• Grade WKK10S optimised for cast iron
• Rhombus 35° geometry for versatile turning
• 0.4 mm nose radius, 0° negative rake

Engineered for high productivity and extended tool life

The combination of the Tiger‑tec Silver series and the WKK10S grade provides a balance of wear resistance and toughness tailored to abrasive cast iron applications. The coated carbide composition reduces flank wear and extends edge life under typical interrupted cutting conditions encountered in foundry components. As a result, cycle times can remain consistent across production batches while maintaining dimensional accuracy. This balance supports efficient machining strategies and reduces the frequency of index changes on multi‑op turning centres.

Reliable chip control for safer, cleaner turning operations

The MK5 chipbreaker is designed to break and guide chips reliably when machining cast iron, helping to prevent long, hazardous swarf and to protect the workpiece surface. Combined with the Rhombus 35° insert geometry and a 0° (negative) rake angle, the chipformer promotes short, fragmenting chips that evacuate predictably. For operators less familiar with chipbreaker functions: the chipbreaker modifies local cutting forces and chip curl to encourage controlled fracture of brittle cast iron chips, improving process stability and reducing secondary operations for swarf handling.

Geometry and dimensions that support versatility on standard tool holders

With a nominal size designation of 16 and a 0.4 mm nose radius, the cutting edge offers a compromise between surface finish and edge strength suitable for both finishing and semi‑finishing passes on cast iron components. The insert thickness and VNMG form make it compatible with a wide range of VNMG toolholders commonly used in turning centres. This compatibility simplifies inventory management and tooling setup, enabling rapid insertion changes and consistent clamping without specialised adaptors.

Process integration and quality assurance in production environments

The insert’s tolerance class M and the coated carbide construction ensure consistent edge geometry and repeatable performance across batches, aiding quality control and process documentation. The specification explicitly supports the machining of cast iron (ISO group K), where the grade is tuned for abrasive wear and the typical short, breaking chip morphology of grey and ductile castings. For engineers planning tool lists or cycle sheets, the insert’s defined geometry and chipbreaker behaviour allow straightforward calculation of cutting forces and tool life projections, supporting both productivity goals and component quality standards.
