Description

The OSG Carbide 4 Flute End Mill with Ball Nose, regular length, and TiAlN coating is a versatile cutting tool designed for contouring, profiling, and 3D machining. With a 20 mm diameter and center-cutting geometry, it delivers precise, reliable performance across a wide range of general machining tasks, from hobby projects to professional production. The four-flute design enables efficient material removal, while the TiAlN coating enhances wear resistance for longer tool life in demanding work environments.

  • Ball Nose Geometry for Smooth 3D Contouring: Delivers clean, accurate curves and gentle transitions for intricate 3D shapes and finished surfaces.
  • TiAlN Coating for Extended Tool Life: Improves wear resistance and heat tolerance, helping the tool stay sharp longer and maintain consistent cuts.
  • Regular-Length, Center-Cutting 4-Flute Design: Provides stable, versatile performance for contouring, pocketing, and general milling with efficient chip evacuation.

This end mill helps you streamline workflows by delivering consistent results with fewer passes and less rework. The combination of carbide hardness, TiAlN protection, and the 4-flute design supports reliable performance across materials, enabling precise finishes and productive cutting in everyday machining tasks.
