Novel high-speed hollow drill bit

Abstract

The invention discloses a novel high-speed hollow drill bit. The drill bit is characterized in that a drill body is composed of a main drill body, a cutting part and a drillstock, one end of the main drill body is connected with the cutting part, the main drill body and the cutting part are integrally formed, the other end of the main drill body is connected with the drillstock, the main drill body and the drillstock are integrally formed, and the drillstock is of a long and thin cylinder structure. According to the drill bit, as a saw-tooth-shaped cutter blade and a ventilation hole are effectively combined, the strength of a drill hole is high, discharging and cutting are smooth, and installing is firm.

Description

technical field [0001] The invention belongs to the field of drill bits, in particular to a novel high-speed hollow drill bit. Background technique [0002] A tool on a drill, drill press, or drilling machine that creates holes in a workpiece or rock. Xu Chi's "Goldbach's Conjecture Oil Head": "In 1956, the drilling materials in our country were a little tight, and the drill bits were not enough." During the work process, the drill bit rotates with the vertical shaft and moves axially at the same time. The soil is cut under the torque and axial force of the drill bit, and loosened under the extrusion and centrifugal force of the working blades, forming a soil flow that is pressed to the pit wall and lifted to the surface along the page. When the soil flow moves to the place where there is no pit wall, the broken soil is thrown around the pit due to the centrifugal force, and the digging process is completed. [0003] The existing drill bit is a solid drill bit, which has t...
