              Lead Angle                                        Neutral Insert vs. Lead Angle Type
              Lead angle (K) on cut-off inserts reduces size of burr
              remaining on workpiece. Increasing the lead angle reduces
              the burr, but also reduces possible feed rates and tool life.
              Therefore, neutral inserts are recommended for parts on
              which a burr is tolerated.
              Insert designations such as TAG R... DGR (R.H.)
              and TAG L... DGL (L.H.) comply with standard
              terms for turning direction. When looking toward the   Lifetime               4
              chuck from the workpiece, R.H.=counterclockwise
              (C.C.) rotation of workpiece and L.H.=clockwise
              (C) rotation of workpiece. C.C. requires right-hand
              inserts; C requires left-hand inserts. A neutral insert
              with 0º lead angle increases D.O.C. capacity.      Chip Control               4
