Long Neck Solid Carbide End Mill
Common end mill length is composed by two parts, cutting flute length and shank length, the cutting flute diameter is very small, below 1mm or 1-3mm, smaller than shank diameter (shank is 4mm or 3.175mm), there is one cone section length connecting the small diameter and shank, we call it neck. The long neck has a long neck as the name indicates, the long neck can avoid the interference between end mill and the workpiece, which is the very important point when mill a deep groove, so the long neck end mill is very good for deep groove milling, also named Deep Groove End Mill.
