A method for manufacturing a handtool head involves rolling an elongate blank comprising many handtool heads which connected headend T by headend T and tailend W by tailend W, then cutting off the blank with length of the handtool head, thereby forming a handtool head. A mill for continuously rolling the handtool head includes an upper roller and a lower roller on which a ring-shape cavity is provided respectively. Both rollers are provided with a driving gear and a driven gear. When the rollers are to be driven, they are driven to rotate in opposite directions at a same speed by the gears. A plate billet is drawn into a mould cavity consisting of the two ring-shape cavities by the two ring-shape cavities after feeding in via an inlet of mill, so as to produce an elongate blank comprising many handtool head connected headend by headend at an outlet of mill. |
