In the past ten years, the research and development and production of medium and high wind pressure down-hole drilling tools in China have made great progress, and the product market has spread all over the world.
It has become one of the fastest developing tools after the top hammer type. However, with the development of the air compressor to the high pressure, the service life of the down-the-hole drilling tool is put forward higher.
At the same time, with the downturn of the mining industry, the user has lowered the construction cost and proposed the drilling efficiency of the down-hole drilling. High requirements, therefore, design and development to meet the market demand, lightweight, efficient, energy-saving and durable down-the-hole drilling tools become mainstream.
