CNMA160612-RK5 WKK10S Tiger‑tec Silver Drehwendeschneidplatte — Walter Tools (Rhombic 80°, for cast‑iron)

CNMA160612-RK5 WKK10S is a rhombic turning insert developed for productive, abrasion‑resistant machining of cast‑iron components in industrial production environments

• Tiger‑tec Silver coated carbide grade WKK10S
• Optimised for abrasive cast‑iron machining
• RK5 chipbreaker for short, controlled chips
• Rhombic 80° form with 1.2 mm corner radius

Increased tool life through advanced coating and grade

The Tiger‑tec Silver coating combined with the WKK10S coated carbide grade is engineered to resist abrasive wear typical of grey and nodular cast irons. This formulation provides a clear production advantage by extending tool life under interrupted cuts and high‑load conditions. The result is fewer indexings and less frequent insert changes, which translates into improved uptime and lower unit costs in serial turning operations. The chemistry and coating structure are optimised specifically for the demands of the K material group, delivering consistent performance where abrasive particles and short, breaking chips are present.

Controlled chips and stable cutting for uninterrupted processes

The built‑in RK5 chipbreaker produces short, well controlled chips that evacuate reliably from the cutting zone. Combined with the negative 0° relief, the geometry delivers a stable cutting edge that reduces vibration and supports repeatable surface quality. These characteristics contribute to higher process stability during heavy cuts and interrupted machining, meaning fewer rejects and a smoother workflow on the shop floor. The insert’s design therefore supports both productivity and operator safety by reducing entanglement and tool‑related interruptions.

Precise geometry for predictable results and easy tool matching

With an inscribed circle of 16 mm, a thickness of 6 mm and a corner radius of 1.2 mm, this rhombic 80° insert offers a reliable fit in standard CNMA toolholders and predictable engagement in profile and roughing applications. The medium tolerance (M) class ensures consistent dimensions across batches, simplifying tool presetting and minimising adjustment time at the machine. These attributes support quick tool changes and consistent part quality, whether used for serial production or smaller batches requiring reproducible results.

FAQ

What materials is this insert designed to machine?
The CNMA160612‑RK5 WKK10S insert from Walter Tools is optimised for machining cast‑iron (ISO material group K) and is particularly suitable where abrasive wear and short chips occur.

How does the RK5 chipbreaker benefit production?
The RK5 chipbreaker on the Walter Tools insert produces short, controlled chips that evacuate reliably, supporting process stability and reducing interruptions during heavy or interrupted cuts.

Which toolholders are compatible with this insert geometry?
The rhombic 80° form with a 16 mm inscribed circle and 6 mm thickness fits standard CNMA toolholders designed for rhombic 80° turning inserts; the medium tolerance class ensures consistent seating and repeatable results.

What advantage does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating on the WKK10S grade enhances resistance to abrasive wear common in cast‑iron machining, extending tool life and maintaining cutting performance under demanding conditions.

Is the insert suitable for finishing and roughing operations?
The combination of a 1.2 mm corner radius, RK5 chip control and the robust coated grade makes the insert versatile for roughing and medium finishing passes on cast‑iron, offering a balance of material removal rate and surface quality.
