A round bar cutting tool (10) and a cutter head (8) provided especially for the same are provided. The cutting tool has a shank with a generally round cross-section for being fixed by clamping means (28, 30) in a cutting tool receiving bore (12) of the cutter head (8). A substantially planar positioning surface (38) which serves as an engagement surface for the clamping means (28, 30) is located along the shank length in an extension of a cutting face (43) formed on the cutting end (40) of the round bar cutting tool (10), parallel to the longitudinal cutting tool axis. The cutting face (43) and the positioning surface (38) lie in the same plane parallel to the longitudinal cutting tool axis. The cutting face is not reground during sharpening and can therefore have a coating which increases the serviceable life of the cutting edge. The clamping means are wedging devices which press with their clamping surface against the positioning surface (38) of the round bar cutting tool (10) in the same direction as the cutting load during operation. The round bar cutting tool (10) and the cutter head (8) can be produced at low cost. The round bar cutting tool has a long service life, can be easily set up in the cutter head (8) and also maintains its set-up during operation under load.
