The invention relates to a guide bar (9) for a saw chain (10) having a sword-shaped base body (16). A peripheral guide groove (11) is introduced into the periphery (17) of the base body (16). an oil-feed channel (22) is provided which opens into the guide groove (11) in the region of the groove bottom (23) and is fed from a transverse channel (21) lying below the groove bottom (23). The inlet opening (20) of the transverse channel (21) is at an outer side (9.1, 9.2) of the base body (16). The position, shape and size of the oil-feed channel (22) as well as the transverse channel (21) can be freely configured. This is achieved by arranging the transverse channel (21) in an insert part (25) separate from the base body (16). The insert part has the oil-feed channel (22). The insert part (25) is mounted in an open cutout (24) of the base body (16). The cutout (24) is open to an outer side (9.1, 9.2) of the base body (16) and extends substantially below the groove bottom (23).
