Commonly used drill bits mainly include twist drills, flat drills, center drills, deep hole drills, and trepanning drills. Reamers and reamers are not capable of drilling solid materials, but they are also traditionally classified as drills. During digging, the drill bit rotates around the vertical shaft and moves axially. The soil is cut under the action of torque and axial force of the drill bit, is broken and loosened under the action of extrusion and centrifugal force of the working blades, forms soil flow and presses the pit wall, and meanwhile, the soil flow is lifted along the page and conveyed to the ground surface. When the soil flow moves to the position without pit wall blocking, the broken soil is thrown to the periphery of the pit due to the action of centrifugal force, and the whole pit digging process is completed; although the drill bit can realize the function of drilling, when the drill bit is damaged in the drilling process, people can only completely replace the drill bit, and the material for manufacturing the drill bit is wasted.
