[0002] Tapping tools are specialized tools used to create internal threads in materials during machining. Key types include manual tappers, machine tappers, and electric tappers. Tapping tools are typically made of high-hardness materials, such as high-speed steel (HSS) or tungsten carbide, to ensure wear resistance and strength during machining. Tapping tool designs typically include different thread sizes and shapes to accommodate varying thread requirements. When using a tapping tool, a hole is pre-drilled in the workpiece, and then the tapping tool forms the threads within the hole.

[0003] A tapping tool for machining disclosed in Chinese patent publication number CN218050705U can automatically spray lubricating oil on the surface of a workpiece during the tapping operation by means of a tapping assembly and a lubricating spray assembly used in conjunction therewith, thereby assisting the tap in tapping operations without the need for manual operation, thereby improving machining efficiency. However, the overall flexibility of the tapping tool for machining is low, and the tapping angle cannot be adjusted according to the actual use requirements of the workpiece, thereby affecting the overall applicability and convenience of the tapping tool for machining.
