CPMW060204-RK6 WKK20S indexable turning insert — Walter Tools, Tiger·tec Silver for cast iron

The CPMW060204-RK6 WKK20S is an indexable turning insert engineered for reliable finishing and medium-duty turning in cast iron, combining a robust chipbreaker and Tiger·tec Silver coating for stable process performance.

• Tiger·tec Silver coated carbide grade WKK20S
• RK6 chipbreaker for stable chip control
• Rhombic 80° plate with 11° clearance angle
• 0.4 mm corner radius for consistent edge life

High productivity through optimised chip control and grade selection

The insert’s combination of WKK20S grade and RK6 chipbreaker is designed to tackle the abrasive nature of cast iron by encouraging predictable, short chips and reducing heat concentration at the cutting edge. This results in fewer interruptions for chip clearing and more consistent cycle times. The Tiger·tec Silver coating supports thermal stability and wear resistance, which together increase the usable life of the cutting edge and lower tool change frequency; the outcome is a measurable improvement in operational efficiency for workshops focused on continuous production.

Geometry that supports accuracy and process security

The rhombic 80° plate form and 11° clearance angle deliver a balance between cutting strength and access to narrow profiles, while the 0.4 mm corner radius provides a defined edge that enhances dimensional repeatability. These geometric attributes reduce the risk of vibration-induced surface defects and contribute to predictable tolerances in turned components. For toolroom planners and production engineers, the insert’s design translates directly into better surface quality and fewer scrap parts when machining grey and nodular cast irons.

Coating and material match for longer tool life

Tiger·tec Silver’s multilayer coating technology is specifically tuned to combat abrasive wear typical of cast iron machining. The coating reduces adhesion and improves heat dissipation, which helps maintain the integrity of the cutting edge under intermittent cutting conditions. Using a coated cemented carbide substrate enhances resistance to flank wear, so the insert sustains useful life across a wider range of feed rates and cutting speeds. The result is improved cost-per-part when compared with uncoated or less optimised grades.

Practical advantages in workshop use and tool management

With a standard plate size and a compact thickness, this insert fits common toolholders and is straightforward to index when a fresh edge is required. The toleranced design and consistent production quality simplify tool inventory management and rotation strategies. For production planners, the straightforward classification under the Tiger·tec Silver family enables easier grade selection for a variety of cast iron tasks, while preserving the ability to switch to other Walter Tools grades if process demands change. If additional machining data or application-specific recommendations are required, technical consultation is available.

FAQ

Is this insert suitable for grey and nodular cast irons?
The CPMW060204-RK6 WKK20S insert from Walter Tools is formulated for cast iron (ISO group K) and performs well on both grey and nodular grades thanks to the WKK20S grade and RK6 chipbreaker.

Which chip control behaviour can be expected with this insert?
The RK6 chipbreaker promotes short, controllable chips during turning in cast iron, improving machining stability and reducing interruptions for chip evacuation.

What makes the Tiger·tec Silver coating advantageous for cast iron machining?
The Tiger·tec Silver coating on the WKK20S grade reduces abrasive wear and improves thermal stability, which helps maintain edge integrity and extends tool life under typical cast iron cutting conditions.

Can the insert be used in standard toolholders for 80° rhombic plates?
Yes, the rhombic 80° form and standard dimensions of this insert make it compatible with conventional holders designed for CPMW-style plates.

How is the corner radius relevant to surface finish and tool life?
The 0.4 mm corner radius offers a compromise between a defined cutting edge for accurate profiles and sufficient edge strength to resist chipping, aiding both surface quality and consistent tool life.
