PARTING USER GUIDE PARTING Lead Angle 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 (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 0° lead angle increases D.O.C capacity. Neutral Insert vs. Lead Angle Type 420 ISCAR
