DTH (Down the Hole) drilling tool including dth hammer, dth bit, and dth drill pipe. DTH bit is mady by tungsten carbide buttons and steel, with special heat treatment to improve the drill bit hardness and drill bit surface is compressed to improve the drill bit wear-resistance. Combine the quality raw material and the mature produce experience makes our DTH drill bit have long service lifeand good performance in thehard formation and widely used for large scale mine (open and underground), open quarry, water-well drilling, tunnel, geothermal drilling, subway engineering drilling, roads, power stations, and other construction projects, we can supply DTH drilling tool with high air pressure, middle air pressure and low air pressure.

PRODUCT DESCRIPTION
This machine is specially used for producing longitudinal welded pipe in metallurgical, construction, transportation, machinery and vehicle engineering industries. With strip steel as the raw material, through cold roll forming and high frequency welding techniques, it produces round pipes and square pipes with required sizes. By making the best of the similar products home and abroad and integrating with our company's years'Â practical experiences, we improved and upgraded the machine and came up with its latest generation. In particular, the advanced technologies namely roll pass design, computer saw PLC automatic control tracking system, UK European continent full digital servo system enable the machine to realize high efficiency, low fault rate, convenience of operation and maintenance, thereby saving investment, both economical and practical, and is equivalent of advanced pipe making machine abroad.
