Abstract

The invention discloses a novel drill having a cooling housing. The novel drill having the cooling housing is composed of a drill handle and a drill body which are connected together. The novel drill having the cooling housing is characterized in that the drill body is composed of a drill bit and a drill body main body which are formed in a whole body, a cooling liquid through hole is disposed in the drill and through the transversal central line, the diameter of the cooling liquid through hole is 0.5 to 1 mm, and the front end of the drill bit is provided with a filer screen. The drill body main body is composed of a drill body front end portion and a drill body rear end portion which are coaxially formed in a whole body, the drill body front end portion has two straight end faces and are 8-shaped, and the drill body rear end portion has two straight end faces and are 8-shaped. The drill handle is a long and thin cylinder, and one end, close to the end portion, of the drill handle is provided with a positioning groove. The drill can be cooled, and chippings cannot jam the cooling liquid through hole through cooperation of the cooling liquid through hole and the filter screen.

Description

technical field [0001] The invention belongs to the field of drill bits, in particular to a novel cold shell 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] In order to increase the cooling effect of the existing drill b...
