Domestic split DTH drilling rig was first produced by Hebei Xuanhua area in the 50s of last century, through continuous investment and its own development, drilling rig performance and technical content greatly improved, has reached or even exceeded foreign split drilling rigs, in the domestic split DTH drilling rig synonymous with "Xuanhua drilling rig". Since 2000, with the establishment of China's environmental protection system, the manufacturing climax of China's integrated drilling rigs has been set off.

DTH impact drilling tools are usually composed of three parts: drill bit, impactor and drill pipe, equipped on the drilling rig (drilling frame), equipped with air compressor to form a rock drilling unit. According to the different compressed air pressures used in DTH impact drilling tools, it is usually divided into three types: low pressure DTH drilling tools (air pressure 0.6-0.8Mpa), medium and high pressure DTH drilling tools (air pressure 1.0-2.0Mpa), and high pressure DTH drilling tools (air pressure greater than 2.5Mpa). Due to the different driving air pressure, the drilling efficiency of DTH drilling tools is also different, and the performance requirements for products are also different, therefore, the product prices of low pressure DTH drilling tools and medium and high pressure DTH drilling tools are also quite different.
