What is long neck end mill?
Common end mill length is composed by two parts, cutting flute and shank , 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 the neck, this neck can give the end mill a smooth transition from small cutting diameter. to larger shank diameter, and enable the small end mill a tougher character with the connecting larger shank . 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.
