Abstract
The utility model discloses a drill bit structure which comprises a tool apron, a hilt and a tool bit. The tool bit comprises a disk-shaped part and a cylindrical part, wherein the disk-shaped part is connected at a front portion of the tool apron in a sleeve mode, and a chamfer is shaped at a lateral of the front end of the cylindrical part. The utility model has the advantages of being simple in structure, easy to achieve, and capable of effectively reducing the shaking degree of the tool bit and the cut-in capacity of the tool bit.
Description
Technical field
The utility model relates to machinery and uses the drill bit field, is specially a kind of drill bit structure.
Background technology
Mechanical part commonly used in the drill bit machinery industry, it is to go out through hole or blind hole in order to drilling on the solid material, and can be to the cutter of existing hole reaming.Drill bit is made up of tool rest, handle of a knife, cutter head, and the drill bit structure of prior art is simple, during boring cutter head shake bigger, it is into inclined to one side to cause cutter head to be prone to.
The utility model content
The utility model purpose provides a kind of drill bit, to solve the bigger problem of cutter head shake of prior art drill bit.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of drill bit structure; Include tool rest, be connected the tool rest rear end handle of a knife, be connected the cutter head of tool rest front end; It is characterized in that: said cutter head comprises that disc portion and the cylindrical portion that is connected the disc portion front end constitute; Said disc portion rear end is socketed in the tool rest front portion, and said cylindrical portion front end sidepiece forms chamfering.
