Description

The OSG Carbide 4 Flute End Mill Square, Long Length Center Cutting, 8mm diameter, is a versatile carbide cutting tool designed for general machining tasks. Its extended reach and four-flute geometry deliver efficient material removal and precise cuts, making it well-suited for milling, slotting, and profiling in deep or hard-to-reach areas.

Whether you’re an engineer, fabricator, hobbyist, or maintenance technician, this end mill provides reliable performance across a wide range of applications, helping you access challenging features with confidence and maintain cutting efficiency throughout the job.

  • Long reach for deep or hard-to-reach work: Access deep pockets, slots, and contours without re-clamping the workpiece, improving workflow and reducing setup time.
  • Four-flute design for efficient material removal: More cutting edges deliver faster material removal and better control, resulting in cleaner slots and smoother finishes with fewer rework cycles.
  • Center-cutting versatility: Center cutting enables plunging, ramping, and profiling in a single tool, making it ideal for milling, slotting, and contouring across general applications.

With this OSG end mill in your toolkit, you gain predictable, high-quality results across a broad range of machining tasks. The extended reach helps you tackle challenging workpieces, the four-flute geometry supports consistent finishes, and the center-cutting design offers versatile operation—from roughing to finishing—so you can complete projects faster and with fewer tool changes.
