LNHU080304-B57T WKK25G – Indexable milling insert, Tiger·tec Gold grade for cast-iron

The LNHU080304-B57T WKK25G is a rectangular indexable insert engineered for high-performance milling of cast iron components in industrial machining environments.

• Tiger·tec Gold coating, high wear resistance
• Optimised for cast iron machining
• Rectangular insert, 0.4 mm corner radius
• Negative rake 0° with B57T chipbreaker

Boost productivity with predictable tool life

The coated carbide grade WKK25G in the Tiger·tec Gold series provides high wear resistance and stable chip formation, leading to longer intervals between tool changes and improved process reliability. The combination of a robust coating and a substrate designed for abrasive cast-iron conditions reduces flank wear and preserves edge geometry, which directly translates into higher productivity and lower machining costs per component. For process planners, these characteristics support consistent cycle times and simplified tool-replacement strategies.

Precision and process security in cast-iron milling

Designed specifically for cast iron, the insert's B57T chipbreaker and negative rake 0° deliver controlled chip flow and secure cutting engagement. The rectangular insert shape together with a corner radius of 0.4 mm helps maintain surface integrity on interrupted cuts and reduces vibration tendencies in heavy-duty passes. As a result, surface finish and dimensional stability are improved while reducing the risk of premature edge chipping—advantages that matter in medium- to high-volume production of grey and nodular cast-iron parts.

Compatibility, handling and recommended applications

The insert conforms to the LNHU08 geometry family and uses the industrial designation for plate thickness and form, allowing integration with toolholders that accept LNHU-format cutting edges. The B57T chip former is optimised for breaking the typically short, brittle chips of cast-iron materials, and the tolerance class H ensures repeatable seating and reliable indexability across tool changes. This makes the component particularly suitable for milling operations where repeatability and tool-change efficiency are priorities. For bespoke process parameters or holder compatibility checks, technical consultation is recommended.
