CCMW060202-RK6 WKK20S – Turning insert for cast iron, Tiger·tec Silver (Walter Tools)

The CCMW060202-RK6 WKK20S is a rhombic 80° indexable insert designed for productive external turning of cast-iron materials in industrial machining.

• Tiger·tec Silver coated grade WKK20S
• Optimised for cast-iron turning
• RK6 chipbreaker for controlled chips
• Rhombic 80° form with 0.2 mm radius

Productivity and process stability for cast-iron operations

The insert is built on the Tiger·tec Silver coating platform and the WKK20S grade, a combination tuned for the abrasive wear and typically short, brittle chips of cast-iron machining. This configuration delivers longer edge life and predictable wear behaviour, which supports higher productivity and fewer indexings per component. The specification emphasises repeatable performance under interrupted cuts and heavy cross-sections, making the insert a practical choice where consistent cycle times and low tool-change frequency are priorities. The coated carbide substrate reduces adhesive and abrasive degradation, improving tool life in demanding grey and nodular cast-iron applications.

Controlled chips and surface quality with engineered geometry

The integrated RK6 chipbreaker provides defined chip formation and evacuation, reducing the risk of built-up edge and improving machining security on interrupted profiles. The insert geometry – a rhombic 80° shape with a 0.2 mm corner radius and a 7° clearance angle – balances cutting-edge strength and surface finish: the small radius improves dimensional control, while the relief angle aids tool engagement in tight contours. For clarification, a chipbreaker shapes the chip to avoid long, stringy swarf; this is particularly relevant when turning cast iron, where short, fragmented chips are desirable to protect workpiece and toolclamping systems.

Practical integration into workshop toolrooms

Marked as size code 06 and thickness code 02, the insert follows established form factors and fits common external turning holders designed for rhombic inserts. The designation on the insert allows quick identification in tool management systems and facilitates spare-part planning. While cutting parameters vary with machine rigidity and alloy, the combination of coated grade and RK6 geometry generally enables stable feeds and depths in standard roughing and finishing operations. For exact speed and feed recommendations, the technical specialists at Metav Werkzeuge can supply tailored process data matched to the lathe, holder and workpiece composition.

Why this insert improves job-shop efficiency

Choosing this grade and geometry supports a cost-effective machining strategy through fewer tool changes and predictable performance, which reduces downtime and scrap risk. The insert’s attributes favour shops that require a robust, repeatable solution for cast-iron turning and who prioritise throughput without sacrificing surface quality. For newcomers to indexable tooling, the construction simplifies inventory: a single grade covers a broad range of cast-iron tasks while delivering stable chip formation and good resistance to abrasive wear.

FAQ

What workpiece materials is this insert intended for?
The CCMW060202-RK6 WKK20S insert is specified for machining cast iron; the WKK20S grade is tailored to withstand abrasive wear common with cast-iron alloys.

How does the RK6 chipbreaker affect machining?
The RK6 chipbreaker produces short, controlled chips that improve swarf evacuation and reduce the risk of chip entanglement during cast-iron turning with this Walter Tools insert.

Can the insert be used for finishing as well as roughing?
Yes; the combination of the WKK20S grade and a 0.2 mm corner radius allows for both productive roughing and controlled finishing passes, depending on cut parameters.

What does the Tiger·tec Silver coating deliver in practice?
The Tiger·tec Silver coating increases wear resistance and thermal stability, which translates to longer edge life and more consistent machining performance on abrasive cast-iron materials.

Is the insert compatible with common holders for rhombic 80° inserts?
The insert follows standard rhombic 80° form factors (size code 06), so it is compatible with holders designed for that geometry; verify clamping and seating with the chosen holder.
