CCMT060208-RK4 WKK10S – Drill and turning indexable insert, Tiger·tec Silver coating (for cast iron) · Walter Tools

A CCMT060208-RK4 WKK10S is an indexable insert engineered for high-performance machining of cast iron in drilling, boring and turning operations.

• Tiger·tec Silver coating for improved wear resistance
• Optimised RK4 chipbreaker for cast iron chips
• Rhombic 80° shape with 0.8 mm corner radius
• Tolerance class M, clearance angle 7°

Predictable chip control for uninterrupted production

The combination of the RK4 chipbreaker and the WKK10S cutting grade gives highly predictable chip formation when working with abrasive cast iron materials. This delivers a clear rational advantage: fewer interruptions from clogged flutes or irregular chip shapes, which translates into higher machine uptime and more consistent cycle times. For production environments where repeatability matters, the controlled chip break reduces rework and improves throughput.

Longer tool life through advanced coating technology

The Tiger·tec Silver surface treatment is a multi-layer coating designed to resist abrasive wear typical of cast iron machining. By reducing flank wear and protecting the cutting edge, the coated cemented carbide substrate extends the service interval of the insert. The result is measurable: fewer index changes per shift and a better cost-in-use ratio for the tooling budget, while maintaining dimensional stability on critical bores and turned surfaces.

Geometry engineered for accuracy and stability

The rhombic 80° form combined with a 0.8 mm corner radius offers a balance between edge strength and accessibility in confined bores or tight turning contours. The moderate clearance angle of 7° and tolerance class M support stable seating in toolholders and repeatable positioning, which helps maintain process accuracy across multiple insert changes. For operators, this means easier set-up and steady surface finishes without frequent adjustments.

Seamless integration into existing toolholding systems

Designed in the popular CCMT format, the insert fits standard CCMT seats and can be used in compact drill heads and turning holders alike. Its coated cemented carbide composition and series designation provide clear selection criteria for procurement and inventory management. For workshop planning, the straightforward grade choice for cast iron simplifies stock keeping and reduces the risk of incorrect insert selection during busy production runs.

FAQ

What materials is this insert suitable for?
The CCMT060208-RK4 WKK10S from Walter Tools is optimised for machining cast iron (ISO group K) and designed to handle the abrasive wear typical of those materials.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating on the WKK10S grade increases wear resistance and helps extend insert life under abrasive cast iron conditions, improving overall process economy.

Can this insert be used in standard CCMT toolholders?
Yes, the CCMT form is compatible with common CCMT-compatible holders used for drilling, boring and turning operations.

What chip behaviour can be expected with the RK4 chipbreaker?
The RK4 chipbreaker produces short, controlled chips when machining cast iron, reducing the risk of chip build-up and improving machining stability.

Is this product suitable for finishing cuts?
With its 0.8 mm corner radius and coated grade, the insert can achieve stable surface quality; however, final surface requirements depend on cutting data and machine stability.
