The Anatomy of an End Mill
Dec 10, 2017· An end mill's overall reach, 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.
