Description

The OSG Carbide 4 Flute End Mill Square, 4.5 mm diameter, is a regular-length, center-cutting tool designed for general machining tasks. It’s a versatile choice for engineers, machinists, and hobbyists who need reliable milling, slotting, and profiling performance in a compact form.

Its square-end geometry and four-flute design deliver clean, precise edges and efficient material removal, supporting consistent results across everyday projects.

  • Four-Flute design for fast, smooth milling: The four cutting edges enable efficient material removal, smoother surface finishes, and higher feed rates for common milling tasks.
  • Center-cutting, regular-length versatility: Center-cutting capability allows plunge milling into pockets and slots, while the regular-length body provides balanced rigidity across a wide range of setups and applications.
  • Carbide construction for durability: Carbide offers excellent wear resistance and long tool life, helping you maintain accuracy through repeated use and challenging cuts.

In daily shop use, this end mill supports reliable, repeatable performance across milling, slotting, and profiling tasks. Expect clean edges, consistent results, and less downtime due to wear, making it a dependable addition to any workshop or production environment.
