OSG Carbide 3 Flute End Mill Corner Radius DLC Coated - For Aluminium - 12mm x R1.5

The OSG Carbide 3 Flute End Mill with a corner radius and Diamond-Like Carbon (DLC) coating is a precision cutting tool designed for aluminum. With a 12 mm cutting diameter, three-flute geometry, and a 1.5 mm corner radius, it delivers controlled material removal and stable performance across pockets, profiles, and contour milling.

The DLC coating provides excellent hardness and wear resistance, helping the edge stay sharp longer and resist built-up edge in demanding aluminum runs. Built by OSG, a trusted name in cutting tools, this end mill offers reliable performance and consistent results for professional machinists and hobbyists alike.

• Three-flute design for efficient material removal: optimizes chip evacuation and provides stable, smooth cuts at a 12 mm diameter, improving cycle times and reducing chatter on aluminum workpieces.
• Corner radius of 1.5 mm for precise, durable corners: delivers clean, accurate pocket and contour finishes while distributing cutting loads to minimize corner breakage.
• DLC coating for wear resistance and longevity: extends tool life in aluminum applications by reducing wear and maintaining edge sharpness through demanding milling runs.

This end mill helps you finish aluminum parts more predictably and efficiently. The combination of a DLC-coated cutting edge, a rigid three-flute design, and a precise corner radius translates to longer tool life, fewer insert changes, and consistently high-quality finishes—supporting faster setup, reliable performance, and improved overall workflow.
