WNMG060404-MK5 WKK20S indexable turning insert, Trigon 80° – Walter Tools

The WNMG060404-MK5 WKK20S is an indexable turning insert engineered for reliable machining of cast iron components in production environments.

• Tiger·tec Silver coating for high wear resistance
• Optimised for cast iron machining (ISO K)
• Trigon 80° geometry for secure chip control
• 0.4 mm corner radius for consistent surface finish

Longer tool life through advanced coating and substrate

The combination of the Tiger·tec Silver coating and the WKK20S grade produces a wear-resistant cutting edge designed for the abrasive nature of cast iron. The coated carbide substrate resists flank wear and abrasion, extending interval times between index changes and reducing overall tool cost per component. The MK5 chipbreaker is matched to the grade to encourage short, fragmenting chips commonly required when machining grey and nodular cast irons; this improves process security in automated turning cells and eases chip evacuation without compromising the cutting edge. For operations where component throughput and predictable tool life are priorities, this specification supports a stable production flow and fewer unscheduled stops.

Geometry designed for repeatable surface quality and stability

The trigon, 80° insert shape with a 0.4 mm corner radius offers a balance between edge strength and surface finish. The blunt negative relief (0°) increases insert robustness under interrupted cuts and hard inclusions that are typical in cast iron workpieces. The M tolerance class and standard plate thickness provide consistent seating and repeatable positioning in the tool holder, which translates into uniform part geometry and reduced scrap rates. For machinists and process engineers, the result is a dependable insert that contributes to dimensional consistency across batches.

Process benefits: chip control, rigidity and compatibility

Integrating this insert into existing turning operations brings measurable process advantages: the tailored chip control reduces nestling and toolholder interference, the solid geometry supports higher feed stability, and the grade’s focus on cast iron enables predictable wear patterns. As a component of Walter Tools’ Tiger·tec Silver range, the insert aligns with modern production demands for productivity and reproducibility. Technical teams benefit from straightforward tool selection for ISO group K materials and can rely on documented performance trends when planning tool rotations. For shops aiming to combine efficiency with consistent quality, this insert offers a practical route to improved cycle times and lower per-part tooling costs.

FAQ

What materials is this insert suitable for?
The WNMG060404-MK5 WKK20S is specifically formulated for cast iron (ISO K) applications, utilising the Tiger·tec Silver coating to manage abrasive wear.

How does the MK5 chipbreaker affect machining?
The MK5 chipbreaker promotes short, controllable chips when using the WKK20S grade, improving chip evacuation and reducing the risk of entanglement in turning operations with Walter Tools inserts.

Is the 0.4 mm corner radius suitable for finishing?
A 0.4 mm corner radius delivers a compromise between edge strength and surface quality; with appropriate feeds, the insert supports consistent finishes while maintaining robustness under intermittent cuts.
