Description

Engineered for general machining, the OSG Carbide 3 Flute End Mill Square is a 14 mm diameter tool with TiAlN coating. Its regular-length, center-cutting geometry makes it a dependable choice for milling, slotting, and profiling across a broad range of materials.

  • Three-Flute Square End for Efficient Material Removal: The 3-flute design balances strong rigidity with effective chip evacuation, delivering steady cutting and good finish on milling, slotting, and profiling tasks at 14 mm diameter.
  • TiAlN Coating for Extended Tool Life: The TiAlN coating reduces wear and heat buildup, helping you achieve longer tool life and more consistent cuts in demanding materials and higher-speed applications.
  • Center-Cutting Regular-Length Construction: Center-cutting geometry enables plunge milling, while the regular-length body provides predictable rigidity and versatility for a wide range of general machining operations.

This end mill is designed to deliver reliable, repeatable results in everyday shop tasks and production runs. Its carbide construction and TiAlN coating help you maintain cut quality, reduce downtime, and complete more work between tool changes. Whether you're profiling intricate contours, slotting tight channels, or milling across flat surfaces, this 14 mm end mill offers consistent performance, a smooth finish, and long service life.
