The guide groove is delimited by a groove base, a first sidewall and a second sidewall positioned opposite the first sidewall. The guide bar has an opening for supply of oil into the guide groove, wherein the opening extends from an exterior side of the guide bar, wherein the exterior side extends in a longitudinal direction of the guide bar, into the guide groove and opens in the first sidewall into the guide groove. An insert is secured in the opening and reduces a free flow cross-sectional area of the opening.
