CCMT09T308-FK6 WKK20S drilling/turning indexable insert — Tiger·tec Silver, for cast iron

CCMT09T308-FK6 WKK20S is an indexable insert engineered for efficient drilling, reaming and turning in cast iron applications, combining a coated carbide grade with a specialised chipbreaker and versatile rhombic geometry

• Tiger·tec Silver coating for extended tool life
• Optimised FK6 chipbreaker for reliable chip control
• Designed for cast iron machining (ISO K)
• Rhombic 80° geometry with 0.8 mm corner radius

High productivity through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WKK20S carbide grade is engineered to extend tool life and maintain consistent cutting-edge performance in abrasive materials. This coated hardmetal grade is tuned for the specific wear patterns encountered when machining cast iron, reducing flank and crater wear and stabilising cutting performance over longer production runs. The result is fewer tool changes and a more predictable process window, which supports higher overall equipment effectiveness and lower unit costs.

Controlled chip formation for safer, continuous operation

Integrated with an FK6 chipbreaker, the cutter pocket geometry promotes short, broken chips typical of grey and ductile cast irons, which assists chip evacuation and reduces the risk of entanglement. The optimised chip control lowers heat concentration at the cutting edge and improves surface consistency, making the insert particularly suitable where clean chip flow and stable machining are required. This leads to improved cycle reliability and easier machine handling in continuous or automated production.

Geometry and edge preparation that add flexibility

The rhombic 80° insert form offers a versatile approach to a range of turning and boring tasks, combining a stable seating in toolholders with accessibility in confined or stepped profiles. A 0.8 mm corner radius provides a balance between edge strength and surface finish, while the 7° clearance angle helps to reduce rubbing and avoid notch formation at the cutting edge. The T3 plate thickness and the size code 09 ensure mechanical rigidity for interrupted cuts and moderate depths of cut without compromising accuracy.

Ready for integration in standard toolholders and production lines

Produced to tolerance class M, the insert fits common CCMT toolholder systems and can be indexed to use multiple cutting edges, improving cost-per-edge economy. The CCMT09T308-FK6 WKK20S insert supports a focused tool inventory strategy for cast-iron work, allowing straightforward replacement and minimal set-up adjustments. Its stable wear characteristics and chip control contribute to consistent part quality and reduced cycle variability, supporting leaner operations and predictable throughput.

FAQ

What materials is this insert intended for?
The CCMT09T308-FK6 WKK20S insert is designed primarily for cast iron machining (ISO K), with the WKK20S grade optimised for abrasive wear and short, breaking chips.

How does the FK6 chipbreaker benefit production?
The FK6 chipbreaker provides reliable short-chip formation in cast-iron applications, improving chip evacuation and reducing the risk of chip entanglement during continuous turning or drilling operations.

Is the insert compatible with standard CCMT toolholders?
Yes, the insert follows the CCMT geometry and, produced to tolerance class M, is compatible with common CCMT toolholders for easy integration and indexing.

What advantages does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating enhances wear resistance and heat management at the cutting edge, which extends tool life and stabilises machining performance on abrasive cast-iron materials.

Can this insert be used for interrupted cuts and roughing?
With a 0.8 mm corner radius and a robust plate thickness, the insert provides mechanical rigidity suitable for interrupted cuts and moderate roughing in cast iron.
