Description

The OSG Carbide Centre Cutting End Mill is a 5 mm diameter ball-nose tool optimized for aluminum machining. It features a long length and a neck to reach deep pockets and intricate features, delivering precise material removal with efficiency for a wide range of users—from engineers and machinists to hobbyists.

  • Extended reach with long length and neck: The extended reach design lets you access challenging workpieces and tight spaces without repositioning, speeding up setups and reducing the need for multiple tools.
  • Ball nose for smooth, accurate contours: The rounded tip creates precise radii and clean finishes on aluminum, producing consistent geometric accuracy across complex profiles.
  • Carbide construction with center-cut geometry: Hard wearing carbide and a center-cut design provide durable, reliable milling performance for aluminum components and steady, repeatable results.

This end mill helps you streamline workflows by delivering dependable performance in aluminum projects, enabling faster progress from roughing to finishing with fewer tool changes and rework. It’s a reliable choice for producing high-quality parts and smooth surface finishes, whether you’re in a professional shop or a workshop setting.
