BCMT090304R-G55 WKK25G milling insert, Tiger‑tec Gold, G55 chipbreaker — Walter Tools

The BCMT090304R-G55 WKK25G is a Tiger‑tec Gold coated milling insert designed for productive machining of cast iron in a wide range of roughing and finishing operations.

• Tiger‑tec Gold coating for extended tool life
• Designed for cast iron (ISO group K)
• G55 chipbreaker for controlled chip formation
• Parallelogram 75° geometry, 0.4 mm nose radius

Predictable chip control for consistent productivity

The insert offers G55 chipbreaker technology tailored to the short, brittle chips typical of cast iron. Controlled chip formation reduces the risk of built‑up edge and improves process stability, which in turn lowers machine idle time and scrap rates. The chipbreaking geometry supports a wide range of feed rates while maintaining a consistent evacuation path, so machining cycles remain reliable even under varying cutting conditions. For production environments, this translates to fewer interruptions and more predictable throughput.

Longer tool life through advanced coating technology

Equipped with the Tiger‑tec Gold coating, the indexable insert combines a wear‑resistant surface with a robust substrate to withstand abrasive cast‑iron mixtures. The coating reduces abrasive wear and preserves the cutting edge, extending service intervals and reducing tooling consumption. In practice, this means fewer insert changes and lower tool‑related downtime, supporting higher overall equipment effectiveness (OEE) in demanding cast‑iron applications. The coated carbide grade is particularly effective where consistent edge retention is required.

Geometry that enhances milling flexibility and accuracy

The insert’s parallelogram 75° geometry and 0.4 mm nose radius provide a balance between edge strength and surface finish capability. The 75° approach allows for versatile tool paths and facilitates flexible tool engagement strategies across different operations, while the modest nose radius helps to achieve acceptable surface quality without compromising edge stability. With a 7° relief angle and tolerance class M, the component supports repeatable clamping and predictable positioning in standard toolholders, contributing to accurate, repeatable results.

Application suitability and integration into production

Marked as grade WKK25G, the insert is optimised specifically for the ISO group K (cast iron), offering a combination of wear resistance and toughness suitable for both roughing and semi‑finishing. The design and coating make the component a cost‑effective choice for series production where abrasive wear is the dominant wear mechanism. For integration, the designation BCMT090304R‑G55 provides the geometry and chipbreaker details needed to select compatible toolholders and programme stable cutting conditions.
