CNMA120416-RK5 CNMA120416-RK5 WKK10S — Turning insert for cast iron, Tiger‑tec Silver (Walter Tools)

The CNMA120416-RK5 WKK10S is a rhombic 80° turning insert with a Tiger‑tec Silver coated carbide grade, optimised for productive machining of cast‑iron components.

• Tiger‑tec Silver coated carbide
• RK5 chipbreaker for stable chips
• Rhombic 80° geometry, 1.6 mm corner radius
• 0° negative rake for robust cutting

High efficiency and controlled chip formation for cast iron

The combination of the Tiger‑tec Silver coating and the WKK10S grade provides enhanced resistance to abrasive wear, which is common when machining cast iron. The RK5 chipbreaker is tuned for the typically short, brittle chips produced from cast materials, enabling predictable chip flow and reduced risk of machine stoppages. This translated technical advantage means fewer interruptions for chip clearance and less unplanned downtime, supporting continuous production cycles and improved process reliability.

Consistent tool life and repeatable surface quality

The coated WKK10S carbide establishes a balance between hardness and toughness suited to abrasive cast‑iron alloys. With a tolerance class M and a controlled edge geometry, the insert maintains a stable cutting edge across prolonged use, which contributes to repeatable component finish and dimensional consistency. The robust 0° negative rake geometry increases edge strength for heavy cuts, while the 1.6 mm corner radius helps to avoid premature edge fracture, extending effective tool life and reducing the frequency of tool changes in batch production.

Practical geometry and straightforward integration into workflows

The rhombic 80° form offers versatility for a range of turning operations where access and approach angles vary. Marked as a CNMA configuration, the insert fits standard CNMA toolholders and the clear identification codes simplify tooling logistics. With plate size code 12 and thickness code 04, the component is suitable for both finishing and semi‑roughing strategies depending on cutting data. For process planning, the combination of chipbreaker, negative rake and corner radius provides a robust baseline that supports consistent machining parameters across shifts and operators.

FAQ

Which materials is this insert intended for?
The CNMA120416‑RK5 WKK10S turning insert from Walter Tools is specifically designed for machining cast iron and is optimised for the abrasive wear and short chip morphology typical of that material.

What is the advantage of the RK5 chipbreaker?
The RK5 chipbreaker on the CNMA120416‑RK5 WKK10S promotes controlled, compact chips when turning cast iron, improving chip evacuation and reducing the likelihood of chip entanglement.

How does the 0° negative rake affect cutting?
A 0° negative rake increases edge strength on the Walter Tools insert, providing greater robustness for interrupted cuts and higher feed rates, which supports stable production in demanding turning applications.

Is this insert compatible with standard CNMA toolholders?
Yes, the CNMA designation indicates compatibility with holders designed for CNMA‑format inserts, facilitating straightforward integration into existing tool setups.

What benefits does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating enhances abrasion resistance and heat management, extending the effective tool life of the WKK10S grade during continuous cast‑iron machining.
