DCMT070204-FK6 DCMT070204-FK6 WKK20S – Turning insert for cast iron (Tiger‑tec Silver) | Walter Tools

The DCMT070204-FK6 WKK20S is a rhombic 55° turning insert designed for robust, repeatable machining of cast iron components with a coated carbide grade optimised for abrasive materials

• Tiger‑tec Silver coating for high wear resistance
• Optimised for cast iron (ISO group K)
• Rhombic 55° insert with 0.4 mm corner radius
• FK6 chipbreaker for reliable chip control

High-performance grade for abrasive cast-iron machining

The Tiger‑tec Silver WKK20S grade provides a coated carbide formulation that balances wear resistance and toughness for abrasive cast-iron applications. This combination reduces flank wear and extends tool life, which directly lowers tool-change frequency and supports uninterrupted production runs. The engineered coating chemistry helps maintain a stable cutting edge under the short, breaking chip behaviour typical of cast iron, delivering consistent results in batch and series production.

Precision geometry for consistent surface quality

The rhombic 55° shape with a 7° clearance angle and 0.4 mm corner radius ensures predictable cutting forces and a repeatable edge line. The geometrical setup contributes to a controllable cutting zone and a reliable surface finish, while the tolerance class M supports interchangeability in tooling systems. These properties make the insert suitable where dimensional reproducibility and a steady process window are required, reducing the need for frequent adjustment and inspection.

Effective chip control and process stability

Equipped with the FK6 chipbreaker, the insert promotes short, manageable chips and prevents entanglement in the tool zone. Improved chip formation reduces downtime for chip clearing and decreases the risk of surface damage on the workpiece. The chip control characteristic is particularly valuable when machining discontinuous or porous castings, where uncontrolled chips can otherwise compromise cycle time and part quality.

Practical application and shop-floor benefits

Designed for ISO group K materials, this turning insert fits a wide range of cast-iron turning tasks from roughing to finishing when balanced feeds and speeds are applied. The coated grade and chipbreaker together enhance productivity and process reliability, making the insert an effective choice for component manufacturers seeking stable operation and longer tool life.

FAQ

What materials is this insert designed for? The DCMT070204-FK6 WKK20S is designed primarily for machining cast iron (ISO group K) and its coated carbide grade is tuned for abrasive cast materials.

How does the FK6 chipbreaker affect machining? The FK6 chipbreaker creates short, controllable chips, improving process stability and minimising interruptions during cast-iron turning.

What are the key geometry values to consider for setup? Important values include the rhombic 55° shape, a 7° free angle and a 0.4 mm corner radius, which together influence cutting forces and surface finish.

Is this insert suitable for finishing as well as roughing? Yes; with appropriately adjusted feeds and speeds the coated WKK20S grade and the insert geometry allow both productive roughing and consistent finishing operations.

Where can recommended cutting data be obtained? Cutting data and application advice are available from Metav Werkzeuge; the Walter Tools grade information can guide initial parameter selection.
