CNMG190612-MK5 WKK10S — Indexable turning insert (rhombic 80°, 0° negative) by Walter Tools

The CNMG190612-MK5 WKK10S is an indexable turning insert designed for productive, wear-resistant machining of cast iron components in industrial turning applications.

• Tiger·tec Silver coating for wear resistance
• Optimised for abrasive cast-iron machining
• Rhombic 80° shape with 1.2 mm corner
• MK5 chipbreaker for stable chips

Increased productivity for cast-iron turning

The combination of the Tiger·tec Silver coating and the WKK10S carbide grade is tuned to resist the abrasive wear characteristic of cast iron. This insert turns short, brittle chips reliably due to its geometry and coating, which translates into longer tool life and fewer tool changes. The 0° negative relief angle provides a robust cutting edge under interrupted cuts and heavy engagement, improving process stability and helping to maintain cycle times in series production.

Predictable chip control and edge stability

Built around the MK5 chipbreaker and a rhombic 80° form, the insert delivers consistent chip control for varying depths of cut, reducing the risk of chip build-up and machine stoppages. The 1.2 mm corner radius adds edge strength, permitting higher feed rates where component tolerances allow. Together these features provide a balance between surface finish and durability, enabling steady, repeatable results on demanding cast-iron workpieces.

Easy integration into standard toolholders and workshops

The ISO designation CNMG indicates compatibility with common turning toolholders, simplifying inventory and changeover. With an inscribed circle of 19 mm and a thickness designation of 06, the insert fits established tool systems and replacement procedures. The tolerance class M supports consistent manufacturing quality, while the ISO material group K confirms the insert’s suitability for cast iron. This predictability reduces setup time and supports leaner production workflows.

FAQ

What materials is this insert suitable for?
The CNMG190612-MK5 WKK10S is designed primarily for cast iron (ISO group K); the WKK10S grade and Tiger·tec Silver coating are optimised for abrasive grey and compacted graphite irons.

How does the MK5 chipbreaker affect machining?
The MK5 chipbreaker on this Walter Tools insert promotes short, controlled chips during turning, improving machining reliability and reducing the likelihood of chip-related interruptions.

What does the 0° negative relief angle mean in practice?
A 0° (negative) relief angle gives a robust cutting edge that tolerates heavier cuts and interrupted machining, enhancing edge stability and tool life in demanding cast-iron operations.

Is the insert compatible with standard CNMG toolholders?
Yes, the CNMG190612-MK5 form conforms to the CNMG ISO designation and fits conventional CNMG toolholders, simplifying insert changes and tooling logistics.

What benefits does the Tiger·tec Silver coating provide?
Tiger·tec Silver improves wear resistance and thermal stability, extending edge life on abrasive cast-iron materials and contributing to more consistent production results.
