DTH Drill Pipe is commonly referred to as twist drill pipe, and there are two types: dry type and wet type. The wet coal drill pipe can be connected to the water supply to inject water. Coal drill pipe is a tool accessory for mining consumables. It is a kind of high-efficiency twist-shaped drill pipe used in coal seam drilling auger. It is generally made of high-quality carbon steel. It is suitable for use in coal electric drill drilling. It is ideal for coal mining. An indispensable tool.
There are two types of coal drill pipes: solid (dry coal drill pipe) and hollow (wet coal drill pipe), with diameters of Φ26, Φ28, Φ30, Φ38, Φ40, etc., according to the needs of drilling and mining, the length is generally 0.5- 6M.
The coal drill pipe is based on the original Top Hammer Drilling Tools, made of high-quality steel pipe and T-shaped steel belt welding structure, and manufactured by advanced pre-stressed winding welding technology. This product is light in weight (45% lighter than the old twist drill pipe), fast in footage, small in dust, drills vertically downwards without leaving cuttings, and the hole is clear and analyzed. The rod body can be used separately from the drill tail, which prolongs the service life. Spring pin or thread connection is convenient and fast.
