SNGX0904ZNN-F57 WKK25G milling insert – Tiger·tec Gold, for cast iron (Walter Tools)

The SNGX0904ZNN-F57 WKK25G is a square, 90° indexable milling insert engineered for productive and reliable machining of cast iron components.

• Tiger·tec Gold coating for high wear resistance
• Optimised F57 chipbreaker for cast iron
• Square 90° geometry for robust milling
• 0° negative rake for stable cutting

Higher productivity for abrasive cast iron

The WKK25G grade, implemented within Walter Tools' Tiger·tec Gold family, is a coated carbide solution tailored to the demands of the ISO K group. It resists the abrasive wear typical of cast iron and copes with frequently short, breaking chips; this translates into high wear resistance and longer tool life under interrupted or heavy engagement. The coating technology reduces flank wear and supports a stable cutting edge, so fewer tool changes are required and production cycles remain smooth.

Secure geometry that reduces downtime

A square 90° insert form, combined with the 0° negative rake, provides structural strength and predictable cutting behaviour during milling operations. The robust geometry makes the insert suitable for medium to heavy cuts where rigidity and repeatability matter. The insert's designation (size 09, thickness 04) ensures solid pocket support and consistent indexability, which helps maintain surface quality and reduces setup iterations in high-volume production.

Chip control and process reliability as standard

The chipbreaker F57 is optimised for cast iron, promoting optimised chip formation and safe evacuation from the cutting zone. Controlled chip shapes prevent re-cutting and tool damage, improving component finish and machine availability. Combined with the coated carbide grade, this leads to enhanced process security and predictable performance in serial production, supporting consistent part quality and lower unit costs over time.

FAQ

What materials is this insert intended for? The SNGX0904ZNN-F57 WKK25G insert is designed for machining cast iron and is optimised for the ISO K material group.

How does the Tiger·tec Gold technology benefit production? Tiger·tec Gold coating on the WKK25G grade provides improved wear resistance and consistent cutting-edge stability, which enhances tool life and reduces total cycle interruptions.

What advantage does the F57 chipbreaker offer when milling cast iron? The chipbreaker F57 creates controlled, short chips suited to cast iron, improving evacuation from the cutting zone and lowering the risk of re-cutting and tool damage when using the SNGX0904ZNN-F57 insert.

Is the square 90° geometry suitable for heavy roughing? Yes, the square 90° geometry combined with a 0° negative rake offers mechanical strength and stability, making it appropriate for medium to heavy roughing operations on cast iron.

Can the insert be indexed to multiple cutting edges? The insert is an indexable design with repeatable seating; users can rotate or index the insert to access fresh cutting edges and maintain consistent performance.
