Consistent edge life from Tiger‑tec Silver for cast iron

The WKK10S grade, part of Tiger‑tec Silver, is a coated cemented carbide designed specifically for abrasive cast iron conditions. The coating improves wear resistance and supports a stable cutting edge under interrupted cuts and abrasive inclusions common in cast components. This results in fewer indexings and longer effective tool life, which directly contributes to reduced tool costs and increased machine uptime. The description of the grade highlights its optimisation for short, breaking chips, which helps maintain process stability across batch and single-piece production.

Controlled chips and predictable surface quality

Geometry and chip control are decisive for efficient turning. The FK6 chipformer is engineered to produce short, manageable chips when machining cast iron, preventing chip entanglement and protecting the workpiece and toolholder. Combined with the rhombic 35° plate form and a 5° relief, the insert enables secure plunge and turning operations with good access to confined contours. A 0.4 mm corner radius balances edge strength and achievable surface finish, supporting consistent part quality without excessive cutting forces.

Stable process performance and practical data for setup

The insert is supplied in a standard industrial designation and fits common toolholders for 16 mm inscribed circle plates, making integration into existing tooling systems straightforward. Tolerance class M indicates medium dimensional accuracy suitable for many general turning tasks where dependable repeatability matters. Execution T and the FK6 chipbreaker make the grade a practical choice for component manufacturers seeking a balance of productivity and finish. For operations prioritising productivity in cast iron, this solution offers measurable benefits in cycle times and tool-change frequency.
