TPMW16T304-RK6 TPMW16T304-RK6 WKK20S – indexable turning insert, Tiger·tec Silver for cast iron (Walter Tools)

A TPMW16T304-RK6 WKK20S indexable turning insert engineered for productive turning of cast iron, offering a triangular 60° form and optimised chip control for stable machining in industrial applications.

• Tiger·tec Silver coating for wear resistance
• RK6 chipbreaker optimised for cast iron
• Triangle 60° form with 0.4 mm corner radius

High process stability and prolonged cutting life on cast iron

The Tiger·tec Silver grade WKK20S is formulated for the abrasive nature of cast iron, delivering consistent wear resistance and reliable edge life under interrupted or continuous cuts. The coated carbide substrate balances toughness and hardness to reduce flank wear and crater development, which translates into fewer tool changes and improved uptime. This grade is specifically adapted to the short, brittle chips typical of cast components and is therefore recommended where repeatable results and predictable maintenance intervals are priorities.

Predictable chip control and secure cutting geometry

Equipped with the RK6 chipbreaker and a triangle 60° format, the insert offers controlled chip formation and evacuation, lowering the risk of built-up edge and workpiece damage. The 0.4 mm corner radius combined with an 11° clearance angle supports stable cutting forces and good surface finish while maintaining edge strength for small to medium cutting depths. The insert’s T3 thickness contributes to rigidity in toolholders, reducing chatter and enabling steady material removal rates for series production.

Productivity advantages for industrial turning workflows

This insert supports efficient setups with three usable cutting corners per indexable plate, enabling rapid rotation and minimal downtime. The combination of coating technology and optimised geometry reduces overall tooling costs by extending life and maintaining surface quality longer between indexings. For manufacturers processing cast iron components, the WKK20S grade provides a practical balance between economy and performance, allowing for higher feed rates or extended tool life depending on the chosen cutting parameters.

FAQ

What materials is this insert designed for?
The WKK20S grade is formulated primarily for cast iron machining; the TPMW16T304-RK6 WKK20S insert performs best when cutting abrasive, brittle cast materials.

How does the RK6 chipbreaker benefit production turning?
The RK6 chipbreaker promotes controlled chip formation and evacuation, reducing the chance of chip entanglement and improving surface finish during high-volume cast iron turning.

How many indexings does the triangular insert offer?
The triangle 60° format provides three usable cutting corners per insert, allowing quick indexing and efficient utilisation of the TPMW16T304-RK6 WKK20S insert.

Is the Tiger·tec Silver coating suitable for interrupted cuts?
Yes, the Tiger·tec Silver technology combines wear resistance with sufficient toughness, making it suitable for interrupted cuts common in cast iron operations.
