CCMT060208-RK4 WKK20S – Turning insert, Rhombus 80°, Tiger‑tec Silver (Walter Tools)

The CCMT060208-RK4 WKK20S is a coated carbide indexable insert designed for precision turning and boring operations in cast iron, combining a rhombic 80° geometry with a specialised chipbreaker for reliable chip control.

• Tiger‑tec Silver coated carbide grade WKK20S
• Optimised for cast iron (ISO K)
• Rhombic 80° insert geometry
• RK4 chipbreaker for short, stable chips

Improved process efficiency through coating and chip control

The combination of the Tiger‑tec Silver coating and the WKK20S grade delivers significantly enhanced wear resistance and lifecycle stability when machining cast iron. The advanced coating technology reduces abrasive wear typical of grey and nodular cast irons, which in turn extends tool life and reduces machine downtime. The integrated RK4 chipbreaker is tuned for the short, brittle chips produced from cast irons, enabling a steady evacuation pattern that lowers the risk of built‑up edge and improves feed stability. These technical characteristics translate into fewer insert changes and a more predictable production rhythm.

Predictable surface finish and repeatable accuracy

The rhombic 80° geometry provides a balanced cutting edge that combines strength with access to the workpiece, while the 0.8 mm nose radius helps achieve a consistent surface finish without compromising edge robustness. The insert’s 7° clearance angle supports low cutting forces and good dimensional repeatability across batch runs. As a coated carbide indexable solution, this insert offers repeatable seating and predictable performance in standard CCMT toolholders, making it straightforward to maintain process tolerances and meet quality targets in serial production.

Easy integration and inventory rationalisation

Available in the common CCMT06 form and a slim 02 thickness specification, the insert fits a wide range of established toolholder systems and is convenient to index and replace. The WKK20S grade is designed as a universal, wear‑resistant solution for cast iron applications, which helps to reduce the number of grades held in inventory while covering a broad spectrum of machining tasks. For shopfloors seeking consistent results and simple tool management, this insert offers pragmatic advantages in both setup speed and ongoing tool control, supporting more efficient work cycles.

FAQ

What materials is this insert designed for?

The CCMT060208-RK4 WKK20S insert is engineered primarily for cast iron machining (ISO K), with the WKK20S grade tuned to resist abrasive wear typical of those materials.

What does the RK4 chipbreaker do?

The RK4 chipbreaker promotes short, controllable chips when turning cast iron, improving chip evacuation and reducing the likelihood of built‑up edge during operation with the CCMT06 insert.

How does the Tiger‑tec Silver coating benefit production?

The Tiger‑tec Silver coating increases resistance to abrasive wear and heat, extending insert life and enabling more consistent performance across long production runs when machining cast iron.

Is this insert compatible with standard CCMT toolholders?

Yes, the CCMT060208-RK4 WKK20S is manufactured in the common CCMT06 form factor and is compatible with widely used CCMT toolholder geometries for straightforward indexing.

What edge preparation and finish can be expected?

With a 0.8 mm nose radius and a rhombic 80° geometry, the insert supports good surface quality and repeatable dimensional accuracy for finishing and medium turning operations.
