SNMA190616-RK5 WKK10S — Square 90° Indexable Turning Insert for Cast Iron | Walter Tools

The SNMA190616-RK5 WKK10S is a square 90° indexable turning insert engineered for productive machining of cast iron, combining a coated carbide grade with a chipbreaker developed for short, brittle chips.

• Tiger‑tec Silver coating for extended tool life
• RK5 chipbreaker tuned for cast‑iron chip control
• Square 90° geometry for versatile turning
• 1.6 mm corner radius for a robust cutting edge

Delivering consistent, cost‑effective cast‑iron machining

The coated carbide grade from the Tiger‑tec Silver family provides a balance between wear resistance and toughness. Together with the RK5 chipbreaker, this combination reduces flank and crater wear under abrasive conditions commonly encountered when machining cast iron (ISO group K). The result is a lower cost per component through longer tool life and fewer indexings. These technical characteristics support stable process parameters and predictable maintenance intervals, enhancing overall shop-floor efficiency. The insert designation SNMA190616-RK5 WKK10S indicates the geometry and grade in a format compatible with established toolholder systems.

Robust geometry for secure cutting and tool life extension

A square 90° insert form with a 1.6 mm corner radius delivers a strong cutting edge that tolerates intermittent cuts and variable chip thicknesses. The 0° negative rake (listed as 0° (negative)) contributes to effective shear control and reduces the risk of edge chipping when encountering hard inclusions in cast iron. The thickness designation 06 and the tolerance class M reflect the manufacturing precision and mechanical stability required in demanding turning operations. These design choices aim to provide predictable behaviour when increasing feed or depth of cut for productivity gains while maintaining surface quality.

Simple process integration and application guidance

The combination of coated carbide technology and a cast‑iron specific chipbreaker makes integration into existing turning processes straightforward. The chipbreaker promotes short, controlled chips, improving evacuation and reducing tool‑holder interference. For process setup, starting parameters may follow Walter Tools recommendations for K‑group materials and then be adjusted for machine power and workpiece specifics. For further machining data or to verify suitability for a particular casting grade, technical advice is available from Metav Werkzeuge; sharing workpiece material details and machine constraints enables targeted recommendations and minimises trial time.

FAQ

What materials is this insert designed for?
The SNMA190616-RK5 WKK10S insert is optimised for machining cast iron (ISO group K), with the Tiger‑tec Silver grade and RK5 chipbreaker tuned to abrasive, brittle chip behaviour.

Is the chipcontrol suitable for long, continuous cuts?
The RK5 chipbreaker on this Walter Tools indexable insert is designed to produce short, controlled chips in cast iron; for continuous heavy cuts, adjust feeds and toolpath to maintain chip evacuation.

How does the 1.6 mm corner radius affect cutting performance?
A 1.6 mm corner radius increases edge strength and improves resistance to radial impacts, offering longer tool life under interrupted cutting and aiding surface robustness.

Can the insert be used on standard holders for SNMA geometry?
The SNMA190616-RK5 WKK10S follows standard SNMA geometry dimensions and is compatible with holders specified for SNMA indexable inserts; verify seat and clamping specifications before assembly.

What advantage does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating enhances wear resistance and heat management during cast‑iron turning, contributing to longer runtimes and consistent component quality with this Walter Tools insert.
