WNMA060408-RK5 WKK10S indexable turning insert – Tiger·tec Silver for cast iron by Walter Tools

WNMA060408-RK5 WKK10S is an indexable turning insert designed for secure, high-productivity machining of cast iron components, featuring a Trigon 80° form and RK5 chipbreaker.

• Tiger·tec Silver coating for cast iron
• RK5 chipbreaker for controlled chips
• Trigon 80° form for stable turning
• 0.8 mm corner radius for smooth finishes

Maximise productivity in cast-iron turning

The Tiger·tec Silver coating combined with the WKK10S grade has been developed to resist the abrasive wear typical of cast-iron machining. This results in longer tool life and fewer indexings, which directly improves uptime and reduces tooling costs. The RK5 chipbreaker is engineered to produce short, easily evacuated chips in brittle materials, so interruptions for chip clearing are minimised and cycle times remain consistent. For production environments where repeatability and reduced machine downtime are priorities, this combination yields measurable efficiency gains.

Geometry that delivers mechanical stability and consistent finishes

A Trigon 80° insert shape provides a robust seating face and improved toolholder support, which reduces vibration and enhances dimensional repeatability. The 0.8 mm corner radius adds edge strength for interrupted cuts while still enabling a fine surface finish when feeds and speeds are set appropriately. The insert’s 0° negative rake contributes to a stronger cutting edge that tolerates heavier depths of cut without premature chipping. These geometric choices are intended to balance strength and finish, making the component processing chain more predictable.

Practical handling and machining recommendations for workshop use

This insert is coded for machining in the ISO group K (cast iron) and is therefore optimised for the short, breaking chip forms typical of these alloys. The controlled chip formation provided by the RK5 geometry simplifies extraction and reduces the risk of chip entanglement on long turning runs. For best results, pair the insert with a rigid toolholder and moderate cutting speeds suited to grey and nodular cast iron; the coated grade supports stable wear behaviour throughout longer shifts. If specification matching or toolholder compatibility is required, Metav Werkzeuge can advise on suitable holders and machining parameters to align with existing shopfloor practices.
