Description
The OSG Carbide 4 Flute End Mill with a Ball Nose is an 8 mm diameter carbide cutting tool designed for general machining tasks. Its ball-nose profile delivers smooth 3D contours and precise profiles on complex surfaces, while the four-flute geometry ensures efficient material removal during contouring and profiling work. The extra-long length expands your reach to deep pockets and challenging features, and the center-cutting design supports plunge milling in a single setup.
The TiAlN coating adds durability by improving wear resistance and heat tolerance, helping the tool keep a sharp edge for longer and maintain consistent performance in demanding jobs. Paired with a rigid carbide core, this end mill is ready to handle a broad range of everyday milling tasks with reliable results.
