Description

The OSG Carbide 2‑Flute End Mill with Ball Nose in a regular‑length body is a versatile milling tool designed for general machining tasks. With an 11 mm diameter, ball‑nose tip, two flutes, and center‑cutting geometry, it excels at contouring, profiling, and light 3D work while delivering efficient material removal and consistent results. Built for durability, it suits aerospace, automotive, and general manufacturing applications where predictable performance matters.

  • Ball Nose Geometry for Smooth 3D Contours: The rounded tip creates gentle radii and smooth surface finishes on complex profiles, reducing machining steps and improving part accuracy.
  • Two‑Flute Design for Efficient Cutting: Fewer flutes promote robust chip evacuation and stable cutting, enabling reliable material removal across a range of common shop materials.
  • Regular‑Length, Center‑Cutting Versatility: Regular length provides a balanced reach and rigidity for pockets, contours, and 3D features, while center‑cutting allows plunge milling and slotting in a single operation.

This end mill helps streamline workflows by delivering consistent, high‑quality finishes across contours, pockets, and 3D features. The ball nose yields accurate radii and smooth surfaces, while the center‑cutting geometry supports plunge milling without extra steps. Crafted from carbide, it resists wear for longer tool life, helping reduce downtime and tooling changes in everyday general machining tasks.
