• Optimised for cast iron (K)
• FK6 chipbreaker for stable chip control
• 7° clearance, Rhombic 80° geometry

Productivity and wear resistance for cast iron production

The coated carbide grade WKK20S, applied with Tiger·tec Silver technology, is optimised for the abrasive wear typical of cast iron machining. Its formulation balances toughness and hardness to maintain a stable cutting edge under the intermittent, brittle-chip conditions of grey and nodular cast irons. The FK6 chipbreaker promotes reproducible, short-chip formation, reducing risk of chip entanglement and improving process reliability. Specifying this grade supports higher productivity by extending tool life and lowering indexable insert change frequency in batch and series production.

Geometry that reduces cutting forces and stabilises machining

The Rhombic 80° shape combined with a 7° clearance angle yields a versatile cutting geometry that balances accessibility and edge strength for internal boring and external turning operations. The 0.4 corner radius helps distribute cutting forces at the nose, diminishing local stress peaks and improving edge robustness during interrupted cuts. Thickness designation T3 provides the mechanical stiffness required for stable clamping in standard toolholders. These geometric choices translate into predictable tool behaviour, improved surface finishes and fewer rejects in demanding casting removal or finish passes.

Practical benefits in process integration and tool management

Integration into existing tool systems is straightforward thanks to the standard CCMT form and consistent tolerances. The insert's indexable nature enables simple repositioning of fresh cutting edges, lowering downtime compared with brazed or solid tools. For process planning, the coated grade and chipbreaker combination supports elevated cutting parameters for roughing operations on cast iron while still permitting controlled finishing passes when required. Using a structured inventory of these inserts can reduce setup variability and contribute to leaner changeover routines on turning centres and boring bars.

Quality assurance and application guidance

Walter Tools' manufacturing standards ensure reproducible geometry and coating performance across batches. For best results, pair the insert with toolholders rated for CCMT-style inserts and verify clamping torque to prevent micro-movements. In abrasive cast-iron work, coolant strategy and cutting speed adjustments can further extend edge life; the WKK20S grade is designed to tolerate typical coolant conditions used in workshop and production environments. The combination of Tiger·tec Silver coating and the FK6 chipbreaker supports consistent part quality and predictable maintenance intervals.

FAQ

What cast-iron grades is this insert intended for?
The CCMT09T304-FK6 WKK20S insert is formulated for cast iron (ISO group K), with the WKK20S grade tuned to handle abrasive wear and short-chip tendencies.

How does the FK6 chipbreaker affect chip formation?
The FK6 chipbreaker on this insert promotes short, manageable chips during cast-iron machining, improving process safety and reducing chip-related interruptions.

Can the insert be used in standard CCMT toolholders?
Yes, the insert follows the CCMT form factor and is compatible with standard toolholders designed for that geometry; correct clamping is essential for repeatable results.

What advantage does Tiger·tec Silver coating provide?
The Tiger·tec Silver coating enhances wear resistance and thermal stability, supporting higher cutting parameters and longer edge life in abrasive cast-iron applications.

Is the insert suitable for finishing as well as roughing?
While optimised for robust roughing of cast iron, the combination of geometry and grade also permits controlled finishing passes when appropriate machining parameters are selected.
