SCMT09T304-FK6 WKK20S square 90° turning insert, Tiger‑tec Silver coating — Walter Tools

The SCMT09T304-FK6 WKK20S is a square 90° turning insert designed for productive machining of cast iron, featuring a Tiger‑tec Silver coating and an FK6 chipbreaker for controlled chip formation

• Tiger‑tec Silver coating for wear resistance
• Optimised FK6 chipbreaker for cast iron machining
• Square 90° form with 0.4 mm corner radius
• 7° clearance angle for stable cutting

Durable coating for abrasive cast iron work

The combination of the Tiger‑tec Silver coating and the WKK20S grade targets the abrasive wear typical of cast iron components. Coating technology provides a protective layer that reduces flank and crater wear, which translates directly into longer tool life and fewer indexings. For production environments where downtime and insert changes are costly, this results in measurable efficiency gains and a more predictable tool-change schedule.

Geometry designed for consistent surfaces and dimensional control

A square 90° insert with a 0.4 mm corner radius and a 7° clearance angle delivers mechanical stability and repeatable contact conditions during turning. The robust geometry reduces vibration and supports a steady cutting edge, producing reliable surface finish and dimensional accuracy. In practice, this means fewer rework cycles and improved first-pass yield when finishing cast iron components.

Chip control that keeps cycles running smoothly

The FK6 chipbreaker has been developed specifically for brittle, breaking chips from cast iron. It promotes short, manageable chip segments that evacuate reliably from the cutting zone, lowering the risk of entanglement and interruption. Improved chip control shortens non-productive time and supports higher uninterrupted cycle times, contributing to overall productivity improvements on CNC lathes.

Practical use and process integration

With a compact T3 thickness and ISO designation matching standard toolholders, the insert integrates easily into established toolpacks for turning cast iron. The substrate and coating combination is optimised for abrasive materials, providing stable edge behaviour under typical cutting forces. For machining strategies, moderate feeds combined with the FK6 geometry usually yield the best balance between tool life and productivity; process trials in the actual production setup are recommended to determine optimal cutting data.
