Description

The OSG Carbide 4 Flute End Mill Square, 4mm diameter, is a long-length, center-cutting carbide end mill designed for general machining. It excels at milling, slotting, and profiling, especially when you need to reach deep or tight spaces.

With four flutes, it combines efficient material removal with precision, and its extended reach helps you access challenging workpieces without sacrificing cutting performance.

  • Long reach for deep and hard-to-reach work: The extended length lets you access deep pockets, slots, and tight areas while maintaining cutting efficiency, reducing changes in setup or tool position.
  • Four-flute design for efficient material removal: Four-flute geometry enables faster material removal and improved rigidity for stable, consistent cuts across a range of general machining tasks.
  • Square end with center-cutting for versatile operations: The square cutting tip and center-cutting capability allow plunging and a variety of milling tasks, including slotting and profiling, in a single tool.

This end mill delivers reliable, high-performance results in general machining workflows, helping you complete tasks more efficiently with clean slots and accurate profiles. Its carbide construction offers long tool life and consistent performance on challenging workpieces, giving you confidence to tackle demanding projects with one versatile tool.
