USER GUIDE PARTING PARTING 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 chuck from the workpiece, R.H.=counterclockwise Lifetime 4 (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.
