SNMA150616-RK5 WKK20S – Indexable turning insert, square 90°, Tiger·tec Silver (Walter Tools)

SNMA150616-RK5 WKK20S is an indexable turning insert designed for productive machining of cast iron with a square 90° geometry and a 1.6 mm corner radius

• Tiger·tec Silver coating for high wear resistance
• Optimised for abrasive cast-iron machining
• RK5 chipbreaker for controlled, short chips
• Square 90° form with 1.6 mm cutting corner

Greater productivity for cast-iron turning operations

The integration of Tiger·tec Silver technology delivers high wear resistance, allowing longer cutting times between indexings and fewer unplanned interruptions. The grade has been developed with the abrasive nature and short, breaking chips of cast iron in mind, so the insert supports consistently high metal removal rates while maintaining dimensional stability. This translates into more efficient cycle times and reduced process variability on serial turning operations.

Controlled chips and consistent edge life reduce downtime

The RK5 chipbreaker is tailored to chip formation in grey and nodular cast irons, producing short, manageable chips and preventing chip entanglement. Combined with the 1.6 mm corner radius, this geometry promotes a stable cutting edge under intermittent or interrupted cuts, leading to predictable wear progression and fewer tool indexing cycles. The result is enhanced machine uptime and simplified chip handling, especially in lights-out or high-volume turning.

Practical handling and secure integration in production

The square 90° plate form offers reliable seat support and multiple effective cutting edges per insert, improving cost-efficiency per edge. The standard designation SNMA150616-RK5 WKK20S fits common toolholders for turning applications, enabling quick insert changes and minimal setup time. Documentation and marking match industrial conventions, supporting traceability and easy stock management in workshops and production cells.

FAQ

What materials is this insert suitable for?
The SNMA150616-RK5 WKK20S is specifically designed for machining cast iron, with the coating and chipbreaker tuned to handle abrasive cast-iron behaviour.

How does the Tiger·tec Silver series improve performance?
Tiger·tec Silver enhances wear resistance and thermal stability; when used with the SNMA150616-RK5 WKK20S, it helps to extend edge life during continuous cast-iron turning.

Which chip control can be expected with the RK5 breaker?
The RK5 chipbreaker on the SNMA150616-RK5 WKK20S produces short, controllable chips, reducing clogging and improving operational safety in turning cycles.

Is the insert compatible with standard turn­ing toolholders?
The SNMA150616-RK5 WKK20S conforms to common indexable insert geometries for square 90° seats and can be integrated with matching toolholders for quick replacement.

What is the benefit of the 1.6 mm corner radius in practical use?
A 1.6 mm corner radius balances edge strength and surface finish, providing a robust edge for interrupted cuts while maintaining acceptable workpiece quality.
