Description

The OSG Carbide 3 Flute End Mill Square is a regular-length, center-cutting tool with a 3 mm diameter. Made from durable carbide, it’s designed for reliable performance in a wide range of general machining tasks, from light milling to precise profiling.

With its three-flute geometry, this end mill delivers efficient material removal and steady cutting, helping you achieve clean edges and consistent finishes across different materials and setups.

  • Three-flute carbide design: Balances rigidity with effective chip evacuation to speed up material removal while delivering a smoother, more consistent surface finish, and featuring durable carbide for longer tool life.
  • Center-cutting square end: Enables plunging and precise side milling with clean, square slots and corners, reducing setup changes and expanding what you can accomplish in a single operation.
  • Regular-length versatility: Designed to work across a broad range of machines and applications, helping minimize tool deflection and maintain accuracy in everyday milling tasks.

With a 3 mm diameter, this end mill is ideal for small features, tight tolerances, and reliable performance in general-purpose milling, slotting, and profiling. Its robust carbide construction and well-balanced 3-flute geometry help streamline your workflow, reduce downtime, and consistently deliver precise results.
