WNMG100616-MK5 WKK10S — Indexable turning insert, Trigon 80° form, Tiger‑tec Silver, Walter Tools

The WNMG100616-MK5 WKK10S is a trigon‑shaped indexable turning insert engineered for efficient machining of cast iron components in industrial turning applications.

• Tiger‑tec Silver coating for high wear resistance
• Optimised for cast iron machining (ISO group K)
• Trigon 80° form with 1.6 mm corner radius
• 0° negative rake with MK5 chipbreaker

Consistent performance for cast iron turning

The Tiger‑tec Silver coating combined with a coated carbide substrate provides enhanced abrasion resistance and predictable tool life when machining abrasive cast iron grades. The insert’s grade WKK10S is specifically developed for the ISO group K (cast iron) and balances wear resistance with toughness to handle the short, brittle chips typical of grey and nodular cast irons. The integrated MK5 chipbreaker promotes controlled chip breaking and evacuation, reducing the risk of chip entanglement and improving machining stability on automated turning centres and conventional lathes.

Robust geometry for interrupted and stable cutting

The trigon 80° insert form and 0° negative rake give a mechanically strong cutting edge, making this indexable insert suited to interrupted cuts and demanding roughing tasks. The 1.6 mm corner radius increases edge robustness and distributes cutting forces, which supports higher material removal rates and consistent surface quality. The negative rake geometry further enhances edge resistance to chipping, while the tolerance class M ensures reproducible seating and repeatable performance in standard toolholders.

Productivity and application advantages

With a compact plate size and the series’ focus on process reliability, this insert is designed to deliver productive machining cycles and easy insert indexing for extended tool life. The insert is suitable for both roughing and medium finishing of cast iron components, offering a balance between economy and surface integrity. Using this indexable insert in a properly set-up holder reduces downtime for insert changes and supports efficient production runs, particularly where predictable tool behaviour and good chip control are essential for cycle-time improvements.

FAQ

What materials is this insert intended for?
The WNMG100616‑MK5 WKK10S insert is optimised for machining cast iron (ISO group K) and the WKK10S grade is tuned for abrasive wear characteristics of those materials.

How does the 0° negative rake affect cutting performance?
A 0° negative rake increases edge strength and resistance to chipping; with the Trigon 80° form and 1.6 mm corner radius, the insert is well suited to interrupted cuts and heavy‑duty turning operations.

Can this insert achieve good chip control?
Yes — the MK5 chipbreaker combined with the Tiger‑tec Silver grade promotes controlled chip formation and evacuation, improving process stability during cast iron turning.

Is the insert compatible with standard toolholders for WNMG form?
The WNMG form is a standard trigon indexable geometry; the WNMG100616‑MK5 WKK10S will seat in holders designed for WNMG inserts with matching size and thickness specifications.

What production benefits does the Tiger‑tec Silver series provide?
The Tiger‑tec Silver coating enhances wear resistance and repeatable tool life, helping to reduce insert change frequency and maintain consistent machining quality over longer production runs.
