WNMG080412-MK5 WKK10S turning insert for cast iron — Walter Tools, Tiger‑tec Silver

WNMG080412-MK5 WKK10S is a trigon 80° turning insert designed for high‑productivity machining of cast iron components with a Tiger‑tec Silver coated carbide grade.

• Tiger‑tec Silver coated carbide
• Optimised for cast iron (K)
• Trigon 80° geometry for stability
• MK5 chipbreaker for consistent chips

Greater throughput through wear‑resistant grade and coating

The combination of the WKK10S grade and the Tiger‑tec Silver coating delivers improved wear resistance and prolonged cutting life when machining abrasive cast‑iron materials. Coated carbide technology reduces flank and crater wear under the typical short, brittle‑chip conditions of grey and nodular cast irons, which leads to longer tool life and fewer indexings. From a process viewpoint, this translates directly into higher uptime on the lathe and a lower cost per component — measurable gains for batch production and serial turning applications.

Geometry and chip control that stabilise the cut

A trigon 80° shape with a 0° negative rake and a 1.2 mm corner radius provides mechanical robustness at the cutting edge and supports consistent surface finish on interrupted or profiled cast‑iron work. The integrated MK5 chipbreaker is tuned for the chip forms typical of cast iron, promoting secure chip evacuation and reducing the risk of rework caused by chip entanglement. In practice, the defined geometry ensures repeatable tolerances and a reliable surface quality with stable cutting forces, which is particularly valuable on less rigid setups or where short cycle times are required.

Practical selection and application guidance for process reliability

Marked for ISO group K, the insert is specifically suited to cast‑iron applications and should be paired with a matching WNMG‑compatible toolholder and appropriate cutting data for the workpiece grade. For general guidance, begin with conservative feeds and speeds and increase within tool life limits while monitoring wear; the WKK10S grade is engineered to cope with the abrasive nature of cast iron while maintaining edge stability. The clear technical match between grade, chipbreaker and geometry simplifies tooling decisions and supports consistent production results across a range of cast‑iron components.

FAQ

What materials is this insert intended for?
The insert is specified for machining cast iron (ISO group K); the WKK10S grade and Tiger‑tec Silver coating are optimised for abrasive cast‑iron behaviour.

Which geometry attributes improve stability in interrupted cuts?
The trigon 80° shape combined with a 0° negative rake and 1.2 mm corner radius provides mechanical strength and consistent surface finish in interrupted or profiled turning.

How does the MK5 chipbreaker affect chip formation?
The MK5 chipbreaker is designed for typical cast‑iron chips, producing short, controllable fragments to aid chip evacuation and reduce the risk of re‑cutting or workpiece damage.

Can this insert be used in heavy‑duty roughing operations?
The coated‑carbide grade and robust trigon geometry support productive roughing in cast iron, though cutting data should be adjusted to machine rigidity and part tolerances.

How should the tool be paired for best results?
Use a compatible WNMG‑capable toolholder and start with conservative speeds and feeds, then increase within observed tool life limits; the Walter Tools grade is intended to deliver stable performance across serial production runs.
