CNMG120416-MK5 WKK10S – Turning insert, Tiger‑tec Silver coating, for cast iron | Walter Tools

The CNMG120416-MK5 WKK10S is a rhombic 80° turning insert engineered for productive finishing and medium‑depth turning of cast iron components.

• Tiger‑tec Silver coating for extended life
• WKK10S grade optimised for cast iron
• MK5 chipbreaker for controlled chips
• Rhombic 80° form with 1.6 mm corner radius

High performance on abrasive cast iron for consistent throughput

The combination of the WKK10S carbide grade and the Tiger‑tec Silver technology provides a marked improvement in wear resistance when cutting abrasive cast iron. These characteristics mean fewer tool changes and longer effective cutting intervals, which supports higher machine utilisation and predictable cycle times. The coated carbide substrate is tuned to handle the short, breaking chips typical of grey and nodular cast irons, converting material behaviour into a repeatable, manageable process.

Controlled chips and stable cutting conditions reduce rework

Equipped with the MK5 chipbreaker, this insert promotes consistent chip formation and evacuation, reducing the risk of workpiece damage and machine stoppage. The stable chip control simplifies coolant and cutting parameter selection, enabling safer operation in both automated and manual setups. The result is fewer interruptions, improved surface quality and lower downstream finishing effort.

Geometry designed for reliable set‑up and dimensional repeatability

The rhombic 80° plate form combined with a 1.6 mm corner radius and a 0° (negative) relief angle delivers a robust edge that tolerates interrupted cuts and variable surface conditions. This geometry supports precise radial positioning and easy indexing, which shortens tool changeover time and helps maintain part tolerances across production batches. Straightforward geometry also aids tool management in multi‑station toolholders.

Economical machining through longer tool life and predictable performance

With a coated, wear‑resistant composition and a grade tailored for cast iron, this insert provides a favourable cost‑per‑part ratio. The material and coating choices reduce flank wear and maintain edge stability, which lowers scrap rates and contributes to consistent surface finishes. For operations seeking to balance throughput and component quality, the insert offers an effective compromise between productivity and tool economy. The Walter Tools pedigree supports reliable sourcing and documented performance characteristics.
