DNMA150608-RK5 WKK10S indexable turning insert for cast iron — Walter Tools (Tiger·tec Silver, Rhombic 55°)

DNMA150608-RK5 WKK10S is an indexable turning insert optimised for cast iron machining; it pairs a wear-resistant coated grade with a chipformer designed for short, breaking chips.

• Tiger·tec Silver coating for wear resistance
• RK5 chipbreaker for predictable chip control
• Rhombic 55° geometry for versatile turning
• 0° negative relief for secure cutting

Longer tool life through advanced coating technology

The combination of the Tiger·tec Silver coating and the WKK10S grade provides enhanced wear resistance in abrasive cast iron applications. The coated carbide composition is engineered to withstand the frequent, brittle-chip conditions typical of cast iron, reducing flank wear and extending service intervals. By selecting a coating technology optimised for abrasive materials, the insert supports more reliable cycle times and fewer tool changes, which translates into measurable production stability and lower overall tooling costs.

Consistent chip control and process reliability

Equipped with the RK5 chipbreaker, this indexable plate produces short, controlled chips that reduce the risk of chip entanglement and improve surface quality. The chipformer geometry is tuned for cast iron (K) and therefore minimises interruptions caused by poor chip evacuation. For operations where repeatable cutting behaviour matters, the predictable chip flow supports higher feed rates and helps maintain steady machining parameters, improving throughput without sacrificing component finish.

Geometry and edge preparation that support precision work

The rhombic 55° insert form and a 0.8 mm corner radius balance strength and profile fidelity for diverse turning tasks. The 55° geometry enables a stable cutting edge while allowing access to a range of part contours; the moderate corner radius reduces edge chipping yet preserves profile accuracy. Additionally, the specified 0° negative relief offers a secure seating and robust engagement in turning holders, which is especially useful for interrupted cuts or unstable setups where insert retention and edge strength are critical.

Clear application focus and simple integration

This insert is explicitly designated for machining cast iron, matching the ISO group K requirements for short, brittle chips and abrasive material behaviour. The designation and series information make it straightforward to match the insert to existing toolholders and machining strategies. For engineers and production planners seeking an insert tuned to cast-iron dynamics, the combination of grade, chipbreaker and geometry simplifies specification decisions and helps standardise tooling across relevant turning operations.
