The present invention relates to an isoparallelometre with at least a tool holding support, comprising: a base (1); a load bearing column (2) mounted o n the base (1); a central block (3) engaged to the load bearing column (2); at least an arm (38) engaged to the central block (3); and at least a tool holding support (41) engaged to the arm (38). The central block (3) is translatable along the load bearing column (2), between a first position (5a ) wherein the central block (3) is situated in correspondence with the base (1 ), and a second position (5b) wherein the central block (3) is situated in correspondence with an end (6) of the load bearing column (2) opposite to th e base (1). The arm (38) is slidingly translatable in a horizontal plane and i s free to rotate in a horizontal plane. Actuating means (7) are provided to translate the central block (3) between the first position (5a) and the seco nd position (5b). The actuating means (7) comprise: a support element (8); a le ad screw (9), having its own vertical longitudinal axis; and rotation means (10 ) to rotate the lead screw (9) about its own axis. The lead screw (9) is rotatorily sustained by the support element (8) and is operatively engaged i n a corresponding nut screw (11) obtained in the central block (3). The tool holding support (41) is rigidly mounted to one extremity of the arm (38), an d a second tool holding support (42) is provided, rigidly mounted to the other extremity of the arm (38), the tool holding supports serving as stops for th e translation of the arm (38). The tool holding support (41) is free to move according to independent cylindrical coordinates.
