CCMT09T304-RK4 WKK10S indexable insert — RK4 chipbreaker for cast iron (Walter Tools)

A CCMT09T304-RK4 WKK10S insert engineered for productive cast iron turning and boring, offering Tiger·tec Silver performance in a rhombic 80° geometry.

• Tiger·tec Silver coated carbide
• Optimised RK4 chipbreaker
• Designed for cast iron machining
• Rhombic 80° insert geometry

Stable chip control for higher process efficiency

The combination of the RK4 chipbreaker and the Tiger·tec Silver coating is designed to control the short, breaking chips typical of cast iron. The chipformer geometry reduces interruptions and decreases tool changes, which in turn supports higher productivity in serial production. For operators with limited metrology background: a chipbreaker channels and fractures chips reliably, preventing blockages and improving cycle consistency while also protecting the cutting edge from irregular loading.

Geometry that improves surface finish and insert life

The rhombic 80° geometry together with a 7° clearance and a 0.4 mm corner radius offers a balanced compromise between cutting strength and accessibility in tight turning grooves. The modest corner radius supports a better surface finish on interrupted surfaces and extends the effective life of the cutting edge under abrasive conditions typical for cast iron. The tolerance class M ensures consistent seat fit and repeatable positioning in standard toolholders, which reduces rework and fixture adjustments on the shop floor.

Versatile application across turning and boring operations

Classified for cast iron workpieces, the grade WKK10S is a coated carbide solution optimised for abrasive wear and frequent short-chip formation. The insert is suitable for both turning and boring set-ups where reliable chip flow and stable cutting forces are required. In production environments the insert’s design supports straightforward integration into common toolholders and boring heads used in machining centres and lathes, allowing shops to standardise tooling across similar cast iron operations.

Practical handling and performance guidance

For best results, pair the insert with tool geometries and feeds matched to cast iron characteristics: medium cutting speeds and steady feed rates produce the intended chip shape and promote consistent wear. The Tiger·tec Silver technology improves thermal resistance and edge stability, which lowers tooling costs per component in longer runs. If application parameters require fine-tuning, consult the technical documentation or our specialists for recommended speed and feed windows tailored to specific cast iron grades.
