Description

The OSG Carbide 2 Flute Ball Nose End Mill (Regular Length) is a precision cutting tool designed for tough jobs. Its ball nose geometry and two-flute design excel at contouring, profiling, and 3D machining in titanium and other difficult-to-machine materials, delivering smooth radii and consistent material removal.

With a 12mm diameter, this end mill provides dependable rigidity and versatile reach for aerospace, automotive, and high-precision fabrication applications. It’s the go-to choice when reliability and accuracy matter most in challenging machining environments.

  • Ball Nose Geometry for Smooth Contouring: The rounded tip produces true radii and smooth surfaces on complex 3D parts, reducing post-processing and delivering consistent results across curved surfaces.
  • Two-Flute Design for Stability and Chip Clearing: Fewer flutes enable better chip evacuation and lower cutting forces in hard materials like titanium, reducing chatter and improving surface finish.
  • Regular Length for Versatile Reach and Rigidity: Balanced length provides useful reach into pockets while maintaining rigidity and tight tolerances during demanding contouring tasks.

This end mill supports faster, more predictable production: you get precise, repeatable contours in tough materials, fewer reworks thanks to stable cutting, and longer tool life from a carbide construction designed for demanding machining environments. It helps improve workflow efficiency, reduce downtime, and deliver high-quality finishes on challenging parts.
