Description
The OSG Carbide 4 Flute End Mill with Ball Nose is a long-length, center-cutting cutting tool designed for general machining tasks. Its ball-nose profile and four-flute design deliver precise contouring, profiling, and 3D work across a range of materials, with extended reach for deeper features.
- Ball Nose geometry for smooth contours: The rounded tip creates accurate radii on 3D surfaces, producing natural-looking finishes and reducing post-machining touch-ups.
- Long-length, high-rigidity design: Extended reach lets you reach deep pockets and complex geometries without sacrificing cutting efficiency or stability.
- Four-flute carbide with center-cutting: Efficient material removal and reliable plunging capability across general materials, delivering consistent chip removal and stable cutting in a variety of applications.
Designed for general machining workflows, this tool delivers consistent results from roughing to finishing. The combination of carbide durability, four-flute efficiency, and extended reach helps you complete more work in fewer passes, reduces setup time, and improves surface quality across contours, pockets, and profiling tasks.
