(Summary description)Currently, Chinese low air pressure DTH bits are ranked from 65mm to 186mm and mainly from 90mm to 125mm. Low air pressure DTH hammers mainly include 90mm, 100mm and 150mm. Low air pressure DTH drilling tools are mainly used in mainland like small projects, small quarries and areas with poor drilling conditions. Now, Chinese domestic low air pressure DTH drilling tools exceed market needs and form a situation of low input, short service life and meager profit. High air pressure DTH drilling tools have strict requirements on material, machining, heat treatment and integral performance. Chinese high air pressure DTH drilling tools mainly include DTH bits of 105mm to 178 mm, and DTH drilling pipes of 76mm to 146mm. Chinese high air pressure DTH drilling tools are mainly manufactured in Changsha City, Hunan Province, Xuanhua City, Hebei Province, Hubei, Huludao City, Liaoning province, and Taizhou City, Zhejiang Province so on.. Among the products, DTH hammers and DTH bits with the diameters larger than 200 mm or less than 76mm have perfect performance. High air pressure DTH hammer and bits of Xuanhua City, Hebei Province are based on the technique of Ingersoll Land in America and Atlas in Sweden. There is a gap between overseas and domestic high air pressure DTH drilling tools in the aspects of material, machining, heat treatment, etc.
