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 chipbreakers are recommended. Modications to inserts and holders are required to perform machining such as radius grooving when using the RG chipbreaker with the GNDF holder for facing. ■ Recommended Cutting Conditions Recommended Cutting Conditions for GNDIS
