SNMA150616-RK7 WKK10S — square 90° indexable turning insert, RK7 chipbreaker | Walter Tools

The SNMA150616-RK7 WKK10S is a square 90° turning insert designed for productive, reliable machining of cast iron components in general turning operations.

• Tiger‑tec Silver coating for long tool life
• Optimised for cast iron (ISO group K)
• RK7 chipbreaker for reliable chip control
• Square 90° insert with 1.6 mm corner radius

Stable wear performance for abrasive cast‑iron turning

The insert uses the WKK10S grade within the Tiger‑tec Silver family, a coated carbide solution tailored to the abrasive nature of cast iron. The coating and substrate combination reduce flank and crater wear under typical grey‑ and nodular‑cast‑iron conditions, which translates into extended tool life and fewer insert changes during a production shift. For workshops seeking predictable economy, this means fewer process interruptions and lower tooling consumption without sacrificing machining stability.

Geometry and chip control for dependable surface quality

A square 90° shape combined with a corner radius 1.6 mm and a negative rake 0° delivers a strong cutting edge and controlled engagement during heavy cuts. The RK7 chipbreaker is designed to produce short, easily evacuated chips when turning cast iron, reducing the risk of entanglement and improving surface consistency. Negative rake geometry increases edge strength for interrupted cuts and hard spots typical of cast materials, giving repeatable results and reduced rework.

Practical integration and productivity advantages on the shop floor

The insert’s nominal size and standard mounting make it compatible with common toolholders used in turning centres, simplifying inventory and changeover. The combination of a robust grade and an effective chipbreaker supports higher metal removal rates and consistent tool life, which together improve overall process efficiency. Technical teams benefit from straightforward tool selection: the insert is engineered specifically for cast‑iron applications, enabling faster setup and more predictable machining windows.

FAQ

What materials is this insert intended for?
The SNMA150616‑RK7 WKK10S insert is designed for machining cast iron (ISO group K), where the WKK10S grade and Tiger‑tec Silver coating address abrasive wear and breakable chip forms.

How does the RK7 chipbreaker affect machining?
The RK7 chipbreaker promotes short, controllable chips in cast‑iron turning, improving chip evacuation and reducing the risk of re-cutting, which benefits surface quality and process consistency.

Is the negative rake suitable for heavy cuts?
Yes. A negative rake 0° increases edge strength and resilience for heavy depths of cut and interrupted surfaces, which supports reliable performance in demanding turning operations.

Can this insert be used with standard toolholders?
The insert’s square 90° format and conventional dimensions make it compatible with standard turning toolholders designed for SNMA‑style inserts, simplifying replacement and stock management.

What production advantages can be expected from the Tiger‑tec Silver series?
The Tiger‑tec Silver coating improves resistance to abrasive wear typical of cast‑iron machining, leading to longer tool life, fewer indexings and more consistent cycle times with reduced tooling costs.
