Description
The OSG Carbide 4 Flute End Mill with Ball Nose, 20 mm diameter, features an extra-long length and a TiAlN coating for center cutting, delivering versatile performance for general machining. With four flutes and a ball nose, it excels in contouring, profiling, and 3D work, delivering precise curves and efficient material removal. The extended reach helps access deep pockets and challenging features without compromising cutting efficiency.
- Ball Nose geometry for smooth 3D contours: The rounded tip delivers consistent curvature on complex surfaces, reducing finishing passes and helping you achieve die-smooth, high-quality contours.
- Extra-long length for deep reach: Access deep pockets and hard-to-reach features without repositioning the workpiece, improving workflow and reducing setup time.
- TiAlN coating + center-cutting, four-flute design: TiAlN enhances wear resistance and tool life, while center-cutting and the four-flute geometry provide reliable plunging and efficient material removal across a range of general machining tasks.
This end mill is designed to streamline workflows, reduce tool changes, and deliver repeatable, high-quality surfaces in contouring, profiling, and 3D machining. Its combination of long reach, durable coating, and proven geometry inspires confidence for demanding jobs and everyday general machining success.
