A cutting and separation head for manual ceramic cutters, the cutting and separation head comprising supports movable on longitudinal guides of the cutter; a body mounted on the supports that can be rotably moved with respect to a first transverse rotary shaft, a grip handle secured to a first end of the body, a cutting tool and a separator provided with a support foot on the ceramic parts to be separated, characterized in that it comprises: - a class 1 lever mounted on a second transverse rotary shaft, the lever of which has a first end on which the foot of the separator is articulated and a second, opposite end; - a first coupling element articulated on the second end of the lever; - at least one spring that acts on the first coupling element and tends to rotate it towards a coupling position with a second coupling element defined in the body of the head, automatically establishing coupling of the first coupling element to the second coupling element and the separator being disposed in an operative position, when the body of the head is folded in an ascending direction, exceeding a first angle (a) of inclination with respect to the horizontal and is maintained at an inclination smaller than a second larger angle (b); - a cam for releasing the first and second coupling elements (10, 12), the cam being mounted on the body and relatively rotatable between a first position and a second position, the cam of which: - automatically acts on the first coupling element, releasing it from the second coupling element when the body is folded in an ascending direction and reaches the second angle (b); - maintains the first coupling element away from the path of the second coupling element when the body of the head is folded in a descending direction and; - automatically releases the first coupling element, the separator being disposed in an inoperative position when the body of the head reaches an inclination smaller than the first angle. - a class 1 lever mounted on a second transverse rotary shaft, the lever of which has a first end on which the foot of the separator is articulated and a second, opposite end; - a first coupling element articulated on the second end of the lever; - at least one spring that acts on the first coupling element and tends to rotate it towards a coupling position with a second coupling element defined in the body of the head, automatically establishing coupling of the first coupling element to the second coupling element and the separator being disposed in an operative position, when the body of the head is folded in an ascending direction, exceeding a first angle (a) of inclination with respect to the horizontal and is maintained at an inclination smaller than a second larger angle (b); - a cam for releasing the first and second coupling elements (10, 12), the cam being mounted on the body and relatively rotatable between a first position and a second position, the cam of which: - automatically acts on the first coupling element, releasing it from the second coupling element when the body is folded in an ascending direction and reaches the second angle (b); - maintains the first coupling element away from the path of the second coupling element when the body of the head is folded in a descending direction and; - automatically releases the first coupling element, the separator being disposed in an inoperative position when the body of the head reaches an inclination smaller than the first angle.
