The Anatomy of an End Mill - In The Loupe

The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.
