TNMG160404-MK5 WKK10S turning indexable insert — Tiger‑tec Silver, for cast iron (Walter Tools)

The TNMG160404-MK5 WKK10S is a triangular 60° turning insert in the Tiger‑tec Silver series, engineered for productive and wear‑resistant machining of cast iron components.

• Tiger‑tec Silver coating technology
• Optimised for cast iron machining
• Triangle 60° form, 0.4 mm nose radius
• MK5 chipbreaker for controlled chips

Increase throughput with a grade built for abrasiveness

The Tiger‑tec Silver WKK10S grade combines a wear‑resistant coated carbide with a geometry optimised for the typical short, brittle chips of cast iron. This results in stable cutting performance during continuous turning and fewer tool changes, which directly supports higher machine uptime and lower cycle costs. The insert’s construction balances hardness and toughness: the coating reduces abrasive wear while the substrate maintains edge integrity, offering a reliable compromise between tool life and cutting stability.

Precise geometry for consistent part quality

A triangular 60° form with a 0.4 mm nose radius and a negative 0° rake angle delivers repeatable contact conditions and dimensional stability in finishing and general turning operations. The insert’s tolerance class M ensures consistent fit and repeatability in the toolholder, reducing setup variation. Those characteristics translate into fewer scrapped parts and consistent surface finishes when machining grey or nodular cast iron, even under varying feed conditions.

Efficient chip control and process security with MK5

The integrated MK5 chipbreaker is designed to break and evacuate the short, fragmented chips typical of cast iron, reducing the risk of chip re‑cutting and stabilising the cut. Controlled chip formation improves safety around the machine and supports unattended cycles. Combined with the Tiger‑tec Silver coating, the MK5 chip control helps maintain a stable cutting edge over multiple passes, meaning predictable performance and lower overall tooling consumption.

Practical application and compatibility

The insert is intended specifically for machining cast iron materials and is identified by the ISO designation TNMG160404-MK5 WKK10S. Its dimensions correspond to standard toolholders for TNMG‑type inserts, enabling straightforward integration into existing turning setups. The negative rake and robust grade make it suitable for medium to heavy interrupted cuts that are common in foundry component machining.

Why choose this Walter Tools grade

Choosing a grade from the Tiger‑tec Silver family offers a proven balance of process reliability and economy for cast iron production. The WKK10S composition emphasises abrasive wear resistance while the insert form and chipbreaker enhance operational stability. For production environments where repeatability and tool change intervals affect throughput, this configuration supports measurable improvements in efficiency and part quality.
