For face grooving, use cutting conditions closer to the lower limit of the recommended cutting conditions to ensure that chips are long. In cut-off applications, reduce the feed rate to around 30% to 50% near the center of the workpiece. As there is less space for chip evacuation when machining internal diameters (particularly small bore diameters), ML/GL/GF Type chipbreakers are recommended. Modications to inserts and holders are required to perform machining such as radius grooving when using the RG type chipbreaker with the GNDF type holder for facing.
