DCMW11T308-RK6 WKK20S turning indexable insert – Tiger·tec Silver, RK6 chipbreaker (Walter Tools)

DCMW11T308-RK6 WKK20S is a rhombic 55° turning indexable insert designed for productive machining of cast iron in industrial turning applications

• Tiger·tec Silver coating for enhanced wear resistance
• WKK20S grade tuned for abrasive cast iron machining
• RK6 chipbreaker for controlled, short chips
• Rhombic 55° form with 7° clearance angle

High-efficiency machining for abrasive cast iron

The insert’s WKK20S carbide grade, developed under the Tiger·tec Silver technology, is engineered specifically for the challenges of cast iron. The coated hardmetal layer reduces abrasive wear and extends tool life, enabling longer uninterrupted cutting periods and fewer insert changes. This advantage translates into higher process efficiency and lower downtime in serial production. By selecting a grade optimised for short, breaking chips, the insert supports consistent cycle times and predictable tool consumption, which simplifies production planning and cost-calculation.

Consistent chip control and surface quality

A core benefit is the RK6 chipbreaker, which is matched to the rhombic geometry to ensure repeatable chip separation and smooth evacuation. The Rhombus 55° form combined with a 7° clearance reduces rubbing on the flank face and helps maintain tool stability, while the 0.8 mm corner radius delivers a balance between edge strength and surface finish. Improved chip control reduces interruption caused by tangled chips and lowers the risk of workpiece damage, supporting reliable surface quality without the need for complex coolant strategies.

Robust form factor for secure tool handling

The insert designation DCMW11T308-RK6 indicates a format that is compatible with standard turning toolholders and offers repeatable seating and clamping precision. The thickness T3 and tolerance class M contribute to secure positioning in the toolholder and stable cutting conditions under varying depths of cut. For workshops seeking predictable component tolerances and longer tool life, this format combines mechanical rigidity with an insert geometry optimised for medium-to-heavy interrupted cuts in cast iron.
