Body made of high quality diamond exploration geology club dedicated steel pipe, drill pipe joints made of high quality alloy steel, tempered by the true air conditioning, greatly improving the fatigue strength and shear strength. The use of advanced production and processing of the friction welding process, with high bending strength, welding firm characteristics. Full use of advanced production equipment, CNC machining equipment, with high production efficiency and stable characteristics. To ensure the requirements of straightness deep hole drilling, the product has a high fatigue strength and long life. I can be based on the actual needs of the user design, production of special specifications and performance of the new T-shaped steel drill products prestressed wound spiral drill pipe, there is a solid core and air-core and other varieties can be used for coal mine gas emissions, water exploration This product has a light weight, high elasticity, easy to bend characteristics, self-aligning function, smooth operation, this product can be used alone or in combination, hollow rod joints sealed by seals. Drill with spring pin connection, automatically lock together, demolition is more convenient, with a hand pneumatic drill rig or strengthen supporting the use of coal, drilling 8-30m. Particularly suitable for high-density probe mine water discharge gas drilling and use, according to the actual needs of the user can choose the production of dry, wet, general use of three types of products. 2. Mine drilling drilling accessories: (1) B19, B22 drill, bolt, coal drill pipe, drill pipe hexagonal hollow bolt grouting, etc. (2) diamond drill bits, carbide drill bits, , PDC drill bits, core bits, air drill, drill connected sets, drill the end (3) bolt tray, air leg, manual cable cutter, manual cable tensioning equipment, tensioning jack, anchor stirrer, anchor Cable blender, bolt tension meter, cable anchor, anchor mining, water filter, oiler, injection valve.
