CNMA160612-RK7 WKK10S — Turning insert, Tiger‑tec Silver, for cast iron (Walter Tools)

The CNMA160612-RK7 WKK10S is a rhombic 80° turning insert crafted for productive machining of cast iron, offering a wear‑resistant Tiger‑tec Silver grade for stable, repeatable results

• Tiger·tec Silver coating for high wear resistance
• RK7 chipbreaker for controlled chip formation
• Rhombic 80° shape with 1.2 mm corner radius
• 0° negative rake for robust interrupted cuts

Reliable chip control that reduces process variation

The combination of the RK7 chipbreaker and the WKK10S coated carbide ensures consistent chip shaping when machining abrasive cast iron grades. The engineered chipformer promotes predictable breakage of short, brittle chips, which reduces the risk of workpiece damage and tool‑holder clogging. As a practical benefit, stable chip flow cuts down unplanned stoppages and supports smoother cycle times on production lines.

Geometry designed for edge security and surface quality

A rhombic 80° configuration paired with a 1.2 mm corner radius and a 0° negative rake gives the insert high mechanical strength at the cutting edge. This geometry is particularly suited to interrupted cuts and heavy engagement typical in cast‑iron turning, where edge stability matters most. The result is a durable cutting edge that maintains dimensional accuracy and surface integrity over longer tool life.

Process integration and predictable productivity gains

The insert follows the ISO designation and tolerance class standards, enabling straightforward insertion into common toolholders and predictable set‑up repeatability. The Tiger‑tec Silver coating on the coated carbide substrate optimises resistance to abrasive wear from cast materials, leading to fewer tool changes and improved overall equipment effectiveness. For production environments, this translates into higher uptime and more consistent batch quality.
