The cutting tool for polyurethane elastomers, which is controllable manually or program-controlled comprising a cutting head ( 10 ) with a driving device ( 20 ), a blade holder ( 30 ) with a cutting knife ( 35 ) has at least one cutting head. The driving device has a driving motor ( 21 ) with a drive shaft ( 22 ) running in cutting head longitudinal axis (L), a cam disk actively connected with the drive shaft ( 22 ) of the driving motor ( 21 ), driven rotating about the drive shaft longitudinal axis (L 2 ), with control surfaces ( 40, 41 ) configured on the side ( 25 a) opposed to the driving motor ( 21 ) and lying in different planes, a roller ( 26 ) actively connected with one of the control surfaces ( 40. 41 ) of the cam disk ( 25 ), a lifting rod or tappet push rod ( 45 ) actuated by means of a spring ( 27 ) which is actively connected with the roller ( 26 ) and the cam disk ( 25 ) over a coupling piece ( 46 ) and which carries at its free end ( 45 a) the blade holder ( 30 ) for the cutting knife ( 25 ).
