TNMG160412-MK5 WKK10S — Turning indexable insert, Tiger‑tec Silver coating, for cast iron (Walter Tools)

The TNMG160412-MK5 WKK10S is a triangular 60° coated carbide insert designed for productive turning of cast iron, offering a robust edge and consistent chip formation for industrial turning applications.

• Tiger‑tec Silver coating for abrasion resistance
• Optimised for cast iron applications
• Corner radius 1.2 mm for stable cutting
• Chipbreaker MK5 for controlled chip formation

Higher productivity through wear-resistant cutting technology

The combination of Tiger‑tec Silver coating and the WKK10S grade provides enhanced resistance to abrasive wear typical of cast iron machining. The coated carbide substrate reduces flank wear and maintains edge integrity over longer tool life, which translates into fewer tool changes and more uninterrupted machining time. Using a coated grade specifically tuned for cast iron means the manufacturing process benefits from consistent component quality and reduced finishing passes, supporting higher throughput in serial production.

Predictable chips and secure process behaviour for safer machining

The integrated MK5 chipbreaker is engineered to break and evacuate the short, brittle chips produced when turning cast iron, improving surface quality and reducing the risk of chip-related interruptions. With a corner radius 1.2 mm and a 0° negative rake, the geometry offers a controlled engagement with the workpiece, delivering stable cutting forces and improved cycle-time predictability. These features assist in maintaining a reliable process window, particularly under interrupted cuts or heavy roughing conditions.

Cost-effectiveness through multiple usable edges and consistent tolerances

The triangular 60° insert shape delivers three indexed cutting corners, enabling efficient use of the insert stock and straightforward re-indexing on toolholders. The tolerance class M ensures dimensional consistency for repeatable set-ups and predictable runout behaviour in high-volume environments. As a turning indexable insert manufactured by Walter Tools, this solution balances durability and productivity, lowering overall cost per part when integrated into standard turning tool systems.
