SNMA150612‑RK5 WKK10S turning insert for cast iron by Walter Tools — Tiger‑tec Silver, RK5 chipbreaker

A SNMA150612‑RK5 WKK10S is a square 90° indexable turning insert with a negative rake and an RK5 chipbreaker, designed specifically for productive machining of cast iron.

• Tiger‑tec Silver coating for long tool life
• RK5 chipbreaker for reliable chip control
• Square 90° form with 1.2 mm corner radius
• Optimised for cast iron (ISO group K)

Consistent chip control for productive turning

The combination of the RK5 chipbreaker and the insert geometry provides predictable chip control, which reduces interruptions and improves process stability when machining cast iron. The chipbreaker has been developed for the typical short, brittle chips of cast materials, so operators benefit from fewer tool stoppages and safer swarf handling. This results in smoother production cycles and less time spent on chip management.

Durable coating and grade for longer tool life

The Tiger‑tec Silver series and the WKK10S grade denote a coated carbide designed to withstand the abrasive wear encountered in cast‑iron turning. The coating increases resistance to flank wear while maintaining edge stability, translating directly into longer tool life and fewer insert changes. For production environments, this means reduced tooling costs per component and improved machining uptime.

Geometry tailored to cast‑iron finishing and roughing

A square 90° insert with a 1.2 mm corner radius and a 0° negative rake offers a balance between edge strength and surface finish. The robust edge supports heavier cuts during roughing, while the corner radius helps to maintain dimensional accuracy under load. Because the insert is optimised for ISO group K (cast iron), it performs reliably across a range of cast‑iron grades without compromising on repeatability or surface quality.

FAQ

What materials is this insert suitable for? The SNMA150612‑RK5 WKK10S is optimised for cast iron (ISO group K) and is designed to handle the abrasive wear and short, brittle chips typical of these materials.

What benefit does the RK5 chipbreaker provide? The RK5 chipbreaker ensures controlled, short chip formation during turning operations, improving process stability and making chip evacuation more predictable.

How does the Tiger‑tec Silver coating improve performance? The Tiger‑tec Silver coating increases resistance to abrasive wear and stabilises the cutting edge, resulting in longer tool life and more consistent surface quality when using the WKK10S grade.

Is the insert suitable for heavy roughing cuts? Yes, the square 90° geometry with a 1.2 mm corner radius and a 0° negative rake provides a robust cutting edge capable of handling heavier cuts while maintaining dimensional accuracy.

How many cutting edges are available per insert and how is indexing handled? The SNMA‑style square insert offers multiple indexable cutting edges; once one edge is worn, the insert can be rotated to a fresh edge and reused, reducing tooling consumption.
