Embodiment Construction

[0017] Reference numerals: 1, main cutter, 2, S-shaped cutter, 3, cutting groove, 4, drill body, 5, drill shank, 6, positioning groove, 7, front end of drill

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0019] The structure of the special drilling drill bit for wood of the present invention is as figure 1 As shown, a stainless steel high-speed drill bit is formed by connecting two parts of a drill handle 5 and a drill body. The two parts of the drill body 4 are integrally formed on the same axis. This structure can not only realize two-stage drilling, one-time forming, smooth cutting surface of the drill hole, but also ensure the stability of the structure of the drill body.

[0020] A main cutting tool 1 and an S-shaped cutting tool 2 are arranged on the front end portion 7 of ...

Abstract

The invention discloses a stainless-steel high-speed drill bit which is formed by connecting a drill handle and a drill body. The stainless-steel high-speed drill bit is characterized in that the drill body is integrally formed by a drill body front end portion with two ends to be 8-shaped bodies with straight end faces and a drill body thing-in-itself of a cylindrical structure on a same axis, a main cutting knife and an S-shaped cutting knife are arranged on the drill body front end portion, the drill handle is of a lathy hexahedron, and a positioning groove is formed in a position, close to the end, at one end of the drill handle. The stainless-steel high-speed drill bit effectively combines the main cutting knife, the S-shaped cutting knife and a chip groove which are made by stainless steel, two-stage drilling and one-time forming are realized, the stainless-steel high-speed drill bit is smooth in chip removal, and service life of the drill bit is prolonged.

Description

technical field [0001] The invention belongs to the field of drill bits, in particular to a high-speed stainless steel 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] Stainless steel high-speed drills are more common...
