Down the hole(DTH) tools manufacturer KINGDRILLING supply DTH Drill Bits with COP shank type are available in a wide range of sizes and with a number of custom design features for optimum performance in a rock formation, which are designed to match all conceivable applications for water well industries, mining and construction.
High air pressure drill bits function by utilizing the force generated by pressurized air to cut through hard materials. When the drill bit is in operation, the high air pressure is directed to the cutting edges, where it creates sufficient force to break and remove the material being drilled. The design of the drill bit, including its cutting structure and geometry, plays a crucial role in determining the efficiency and effectiveness of the drilling process.
The rotation of the drill bit, combined with the high air pressure, allows it to bore into the material, creating holes of various sizes and depths. The precise cutting action of the drill bit ensures that the holes are clean and accurately sized, meeting the requirements of the project specifications. High air pressure drill bits are capable of drilling through a wide range of materials, including rock, concrete, metal, and other hard substances encountered in industrial drilling operations.
