SNMA120408-RK5 WKK10S turning insert — Tiger·tec Silver, for cast iron — Walter Tools

SNMA120408-RK5 WKK10S is a square 90° indexable turning insert designed for machining cast iron with a coated‑carbide grade optimised for abrasive wear and short, breaking chips

• Tiger·tec Silver coating for long tool life
• Optimised for cast iron machining
• RK5 chipbreaker for controlled chips
• Square 90° geometry with 0° negative rake

Increase uptime with a wear‑resistant grade and precise geometry

The SNMA120408‑RK5 WKK10S insert pairs a Tiger·tec Silver coating with a coated carbide substrate to resist abrasive wear typical of cast‑iron workpieces. The result is a measurable reduction in insert consumption over repetitive turning cycles, which translates into fewer tool changes and more stable production. The square 90° format and a 0° negative rake contribute to robust cutting edge support, making the component especially suitable where short, brittle chips and high abrasion are the dominating challenges.

Consistent chip formation and machining quality through RK5 design

The RK5 chipbreaker is engineered for effective fragmentation of cast‑iron swarf, improving process safety and evacuation at the tool nose. Controlled chips reduce the risk of surface damage and machine downtime while facilitating higher feed rates where appropriate. By combining chip control with a 0.8 mm corner radius, the insert offers a balance between edge strength and surface finish, so operators achieve reproducible part quality without complex parameter tuning.

Practical integration and application guidance for production

Installation and setup follow standard indexable tooling practices; the insert fits toolholders that accept the SNMA geometry and thickness classification. The WKK10S grade is targeted at material group K (cast iron), providing predictable performance across a range of grey and nodular cast irons. For process improvement, consider modest increases in cutting speed before raising feed, monitoring tool life and surface integrity; technical consultation from Metav Werkzeuge can support parameter optimisation for specific machine and casting formats.
