SNMX120520-F57 WKK25G — Milling insert for cast iron (Tiger‑tec Gold) by Walter Tools

SNMX120520-F57 WKK25G is a square milling indexable insert designed for productive machining of cast iron components, featuring a Tiger‑tec Gold coating and a negative 0° relief angle.

• Tiger‑tec Gold coating for wear resistance
• Optimised chipformer F57 for cast iron chips
• Square 90° geometry with 2 mm corner radius
• Negative 0° relief angle for robust milling

Durable wear protection for abrasive cast iron milling

The Tiger‑tec Gold coating combined with the WKK25G grade delivers high abrasion resistance tailored to the short, brittle chips typical of cast iron. This insert is a coated carbide design optimised to reduce flank and crater wear, which translates into longer tool life and fewer tool changes on milling operations. The result is improved process stability and more predictable tool consumption in series production.

Reliable chip control and stable cutting performance

Equipped with the F57 chipformer, the insert shapes and breaks chips effectively during interrupted or continuous milling of grey and nodular cast irons. Controlled chip formation reduces the risk of built‑up edge and coolant interruptions, enabling consistent surface quality and safer chip evacuation in milling fixtures. The combination of chipbreaker geometry and coating creates a measurable productivity gain when machining abrasive cast iron alloys.

Robust geometry for demanding milling conditions

The square 90° form with a 2 mm corner radius and a negative 0° relief angle makes this insert particularly suited to heavy‑duty face and shoulder milling where cutting forces are high. The geometry provides a secure seating and a strong cutting edge that resists chipping under load, decreasing the frequency of indexing and supporting higher metal removal rates while maintaining dimensional accuracy.

Application guidance and process benefits

This insert is primarily intended for machining cast iron according to ISO group K; it is not specified for stainless or hardened steels. When matched with appropriate cutter bodies and cutting data, the grade and coating support a cost‑effective balance between tool life and productivity. For versatile setups in production environments, the insert offers reproducible results and easier integration into existing milling strategies.

FAQ

What materials is this insert intended for?
The insert is optimised for machining cast iron (ISO group K); the Tiger‑tec Gold grade and chipformer F57 are tuned to handle abrasive, short‑breaking chips in these materials.

How does the negative 0° relief angle affect performance?
A negative 0° relief angle gives a robust edge to the insert, improving resistance to chipping under heavy cuts and supporting stable milling in demanding applications.

Can the SNMX120520-F57 WKK25G be used for finishing passes?
While the insert excels in productive and heavy‑duty milling of cast iron, controlled finishing can be achieved by adjusting cutting parameters and using appropriate machine rigidity; consult tooling data for optimal feeds and speeds.

What benefits does the Tiger‑tec Gold coating provide?
The Tiger‑tec Gold coating enhances abrasion resistance and extends tool life in abrasive workpiece materials, contributing to fewer tool changes and greater process uptime.

Is the insert compatible with standard square milling cutter bodies?
The insert conforms to common square‑indexed geometries and is compatible with cutter bodies designed for SNMX‑style inserts; ensure correct seat and clamping for safe operation.
