The invention relates to a horizontal cold tapping machine tool, and belongs to the technical field of cold tapping machine tool equipment. The horizontal cold tapping machine tool mainly solves the technical problem that an existing cold tapping machine tool is small in machining range and low in machining precision. According to the technical scheme, the horizontal cold tapping machine tool comprises a workbench, a workpiece axial feeding device and a roll feeding device, wherein the workpiece axial feeding device is disposed on one side of the workbench, and the roll feeding device is disposed on the other side of the workbench; the workpiece axial feeding device includes a motor, a synchronous belt, a ball screw, a workpiece shaft feed box, an indexing system, a first gear set, a workpiece shaft and a three-jaw chuck; and the roll feeding device includes a brake motor, a second gear set, a left and right rotating ball screw, a left roll feed box, a right roll feed box and two setsof roll devices. The horizontal cold tapping machine tool has the advantages of wide machining range, high machining precision and the like.
