Micro diameter four flute long neck square carbide end mill
Wholesale Custom Micro-Diameter Four-Flute Long Neck Square Carbide End Mill is designed for ultra-precision machining of miniature features. Made from sub-micron carbide, it ensures exceptional rigidity, sharp edges, and stable performance at very small diameters.The four-flute geometry provides balanced cutting, smooth feeds, and superior surface quality, while the long neck allows deep-pocket access with minimal interference. Optimized helix and edge design reduce vibration and support efficient chip evacuation.Ideal for micro-molds, medical devices, connectors, and precision electronics, the tool supports full customization—diameter, neck length, flute length, shank style, tolerance, and coatings —for reliable, high-accuracy CNC micro-machining.
