Description

The OSG Carbide 4 Flute End Mill Square is a high-performance cutting tool designed for general machining. With a 16 mm diameter, four flutes, and carbide construction, it delivers dependable material removal and precise results across a broad range of applications. Its square end and center-cutting geometry make it versatile for milling, slotting, and profiling. The tool's extra-long length adds reach for deep pockets and hard-to-reach features, enabling more work in a single setup.

Whether you're creating slots, profiling complex contours, or cleaning up deep cavities, this end mill maintains rigidity and a consistent cut. The four-flute design balances aggressive material removal with controlled chip evacuation, helping you achieve clean edges and reliable surface finish in a variety of projects.

  • Extended reach for deep pockets and hard-to-reach areas: The extra-long length lets you access deep slots, pockets, and tight radii without re-clamping or swapping tools, reducing setup time and increasing part throughput.
  • Four-flute design for efficient cutting and finish: Four flutes provide robust material removal while maintaining rigidity, helping you achieve clean slots and a consistent surface finish across a range of materials and feeds.
  • Centre-cutting carbide for versatile plunging and profiling: Centre-cutting geometry enables plunge milling, slotting, and profiling from the edge, while carbide hardness delivers long tool life and reliable performance in demanding jobs.

With its extended reach, durable carbide construction, and centre-cutting geometry, this end mill helps you complete challenging milling tasks faster and with greater accuracy. Expect consistent tolerances on deep slots and profiles, fewer tool changes, and less fixture reconfiguration. In both prototyping and production environments, you’ll experience smoother cuts, reliable throughput, and longer tool life, maximizing your investment.
