SNMX120520-D27 WKK25G milling indexable insert – Tiger·tec Gold for cast iron

The SNMX120520-D27 WKK25G is a square milling indexable insert designed for productive machining of cast iron, offering a Tiger·tec Gold coated carbide grade and a chipbreaker for controlled swarf flow

• Tiger·tec Gold coated carbide grade WKK25G
• Optimised for cast iron machining K group
• Square 90° form with corner radius 2
• Chipbreaker D27 for stable chip control

Reliable performance for abrasive cast iron work

The Tiger·tec Gold coating combined with the WKK25G grade delivers a balance between wear resistance and toughness that is particularly suited to abrasive cast iron materials. The insert is a coated carbide solution developed to tolerate the short, often brittle chips typical of castings while maintaining a stable cutting edge. This results in fewer interruptions for tool changes and a reduction in unexpected downtime. The design supports steady metal removal rates and helps to maintain component tolerances over longer tool lives, which contributes to predictable cycle times in production environments.

Improved chip control and edge stability for safer machining

Engineered with a negative 0° rake and a chipbreaker D27, the insert controls chip formation and evacuation to reduce the risk of recutting and tool damage. The square 90° geometry and corner radius 2 provide robust edge support for interrupted cuts and roughing operations, increasing resistance to mechanical shock. These features mean the insert performs reliably in demanding milling tasks, offering consistent surface quality and repeatable results when used with appropriate feeds and speeds for cast iron applications.

Practical selection and process benefits on the shop floor

Marked tolerance class M and the execution code X indicate measured production tolerances and a standardised fit for clamping systems, simplifying inventory matching and tool change routines. The insert’s size code and design facilitate quick identification and replacement in modular toolholders, lowering setup time between jobs. For operations seeking to improve throughput while containing tooling costs, the combination of Tiger·tec Gold technology and a geometry optimised for cast iron provides measurable gains in productivity and tool life without complex process changes.

FAQ

What materials is this insert intended for?
The SNMX120520-D27 WKK25G insert is optimised for machining cast iron (material group K) and is designed to handle the abrasive wear and short chip form typical of those workpieces.

What advantages does the Tiger·tec Gold grade provide?
Tiger·tec Gold enhances wear resistance and edge stability on the WKK25G grade, giving the insert longer life and consistent performance in demanding milling of cast iron components.

How does the chipbreaker D27 affect machining?
The D27 chipbreaker on this insert promotes controlled chip formation and evacuation, reducing the likelihood of recutting and improving surface finish consistency during milling operations.

What do the codes 05 and M indicate?
The thickness code 05 refers to the plate thickness designation used for tool matching; tolerance class M denotes the manufacturing tolerance level, aiding correct fit and repeatable positioning in toolholders.
