Percussion drilling is a manual drilling technique in which a heavy cutting or hammering bit attached to a rope or cable is lowered in the open hole or inside a temporary casing. The technique is often also referred to as 'Cable tool'. Usually a tripod is used to support the tools. By moving the rope or cable up and down, the cutting or hammering bit loosens the soil or consolidated rock in the borehole, which is then extracted later by using a bailer. Just as with hand augering, a temporary casing of steel or plastic may be used to prevent the hole from collapsing. When the permanent well screen and casing are installed, this temporary casing has to be removed.

Although China’s current decline in the automotive market has occurred, Japanese auto parts manufacturers believe that the Chinese market is still a growing market in the medium to long term, so it has recently stated that it wants to expand investment. Japan's auto parts company has accelerated the development of its business in China. Japan Otaru Manufacturing Co., Ltd. invested 6 billion yen to set up a third factory in China to produce high-performance headlights. Yuguang Brake Industrial Co., Ltd. invested 3 billion yen in three years and owned the first factory in China. Japan’s Otaru will open a new factory in Shanghai in 2006 through the Shanghai Kosaka light. Now, the annual output of Shanghai Xiaoxuan's headlamps is 2 million units, and after three years, the output will increase to 2.5 times now. It is also planned to produce a light system that changes according to the operation of the steering wheel and the illumination range of the headlight. Calsonic Kansei will invest 4 billion yen in the autumn of 2006 to open a new plant in Wuxi and Xiangfan City in Hubei Province. The company will produce heat exchangers for radiators in Wuxi and produce interior products in Xiangfan. After the start of the above two factories, the company will have five production plants in China.
- Percussion drilling can in principle deal with most ground conditions.
- Can drill hundreds of feet (one well hand-drilled in China in 1923 was over 4000 feet deep).
- Can drill further into the water table than dug wells, even drilling past one water table to reach another.
