A cutting head for an apparatus suited to strip a cable, comprising: - a protective casing, - at least one stop arranged fixed in translation relative to the casing intended to bear against a cable to be stripped, - a cutting blade, with a substantially circular shape, intended to cut a sheath wrapping the cable to be stripped, - a handling element arranged movable in rotation around an axis R orthogonal to the axis T, adapted to act on setting means for setting a cutting depth defined as being the maximum distance between said at least one stop and the edge of the blade, said setting means comprising a cam mechanism which, when the handling element is rotated, causes the movement of the blade in translation so as to adjust the cutting depth, characterised in that the blade is arranged movable in translation according to an axis T relative to the casing and in that said cam mechanism comprising: • a cam mechanically linked to the handling element and including a cam profile extending around the axis R of rotation of the handling element substantially according to a spiral-like shape, • a slider slidably arranged within the casing, to which is fastened the blade, said slider comprising a follower finger cooperating with the cam profile, and in that the blade is movable in rotation around the follower finger so as to be able to be driven in rotation when cutting a sheath of a cable to be stripped, and in that a plate comprising an aperture adapted to enable the movement of the follower finger in the cam profile is interposed between the blade and the cam. - a protective casing, - at least one stop arranged fixed in translation relative to the casing intended to bear against a cable to be stripped, - a cutting blade, with a substantially circular shape, intended to cut a sheath wrapping the cable to be stripped, - a handling element arranged movable in rotation around an axis R orthogonal to the axis T, adapted to act on setting means for setting a cutting depth defined as being the maximum distance between said at least one stop and the edge of the blade, said setting means comprising a cam mechanism which, when the handling element is rotated, causes the movement of the blade in translation so as to adjust the cutting depth, characterised in that the blade is arranged movable in translation according to an axis T relative to the casing and in that said cam mechanism comprising: • a cam mechanically linked to the handling element and including a cam profile extending around the axis R of rotation of the handling element substantially according to a spiral-like shape, • a slider slidably arranged within the casing, to which is fastened the blade, said slider comprising a follower finger cooperating with the cam profile, and in that the blade is movable in rotation around the follower finger so as to be able to be driven in rotation when cutting a sheath of a cable to be stripped, and in that a plate comprising an aperture adapted to enable the movement of the follower finger in the cam profile is interposed between the blade and the cam. • a cam mechanically linked to the handling element and including a cam profile extending around the axis R of rotation of the handling element substantially according to a spiral-like shape, • a slider slidably arranged within the casing, to which is fastened the blade, said slider comprising a follower finger cooperating with the cam profile,
