Description

The OSG Carbide Centre Cutting End Mill is built for aluminium workpieces. With a square-edge design and a long-length configuration, it’s ideal for machinists who need precision cuts in tight pockets or deep cavities.

This 25 mm diameter carbide end mill delivers reliable performance across a range of aluminium applications, combining direct plunge-cut capability, stable cutting, and efficient chip evacuation to help you produce high-quality components and parts.

  • Centre-cutting carbide design: Plunges directly into aluminium surfaces for efficient material removal and consistent chip formation, enabling versatile milling with minimal setup.
  • Long-length reach: Extended flute length provides deep reach into pockets, slots, and thick workpieces while preserving rigidity and stable cutting.
  • Square-edge, durable carbide: Sharp, square edges deliver clean corners and precise finishes in aluminium, with wear-resistant carbide for longer tool life in demanding workloads.

Designed for engineers, builders, and hobbyists working with aluminium, this end mill helps you complete parts faster with repeatable accuracy. The combination of centre-cutting capability, extended reach, and robust carbide edge supports smoother workflows, fewer tool changes, and consistently high-quality surface finishes.
