CNMG120408-RP5 CNMG120408-RP5 WKK10S (WKK10S) — indexable turning insert, Tiger·tec Silver for cast iron, Walter Tools

CNMG120408-RP5 WKK10S is an indexable turning insert engineered for productive cast‑iron turning with a robust RP5 chipbreaker and a rhombic 80° geometry

• Tiger·tec Silver coating for abrasion resistance
• Optimised RP5 chipbreaker for controlled chips
• 0.8 mm nose radius for consistent finishes
• Rhombic 80° geometry for versatile turning

Enhanced wear resistance for abrasive cast‑iron machining

The combination of the Tiger·tec Silver coating and the WKK10S cutting grade is designed to address the high abrasive wear typical of cast‑iron workpieces. The coated carbide substrate gives a clear advantage in applications with short, brittle chips, offering improved tool life and reduced frequency of insert changes. For manufacturers seeking steadier production cycles, this insert reduces unscheduled stops through consistent wear behaviour and predictable regrinding intervals.

Consistent chip control and surface quality

Equipped with the RP5 chipbreaker and a 0.8 mm corner radius, the insert ensures reliable chip formation and evacuation during interrupted cuts and variable depth passes. The negative rake (0°) and rhombic 80° format support stable cutting forces, which translates into repeatable surface quality and dimensional control on cast‑iron components. This combination is particularly suitable for medium to heavy turning operations where chip control and workpiece integrity are critical.

Productivity through geometry and tolerance stability

The rhombic profile coupled with the insert’s tolerance class M and execution G supports accurate seat fit and repeatable clamping in standard toolholders. This stability in mounting reduces runout and vibration, improving cycle times and enabling higher material removal rates while maintaining component finish. The plate thickness and geometry balance mechanical strength with accessibility in diverse tool setups, making the insert a practical choice for batch production as well as continuous turning lines.

Application scope and practical handling

Specifically optimised for cast iron (ISO group K), the insert’s coated grade suits abrasive grey and nodular cast iron where short, breaking chips are common. The design minimises burr formation and eases chip disposal in automated environments. For process planning, refer to existing machining tables for coated carbide grades and adapt feed and depth parameters to the 0.8 mm nose radius to preserve edge life.
