In view of the deficiencies of the prior art, the utility model provides a kind of twolip single flute drill header structure, by once drilling
Operation can complete the drilling processing of counter sink on product, and the processing so as to the counter sink to product is brought convenience.
The twolip single flute drill header structure of the utility model, including drill body, the right end of drill body are provided with the first brill
Bar portion is provided with the second rod portion in the middle part of drill body, and the second rod portion connects with the first rod portion, the second rod portion it is outer
Diameter is greater than the outer diameter of the first rod portion, forms step-like structure between the second rod portion and the first rod portion.
The twolip single flute drill header structure of the utility model, wherein the outer wall of the drill body on the left of the second rod portion
On be provided with annular convex platform.
The twolip single flute drill header structure of the utility model, wherein on the outer wall of the drill body on the left of annular convex platform
If being provided with arterial highway in circumferential equally distributed non-slip groove, per pass non-slip groove extends along the radial direction of drill body.
The twolip single flute drill header structure of the utility model, wherein the vertical section of non-slip groove is trapezoidal shape structure.
The twolip single flute drill header structure of the utility model, wherein the left end of drill body be provided with from right to left gradually to
The circular cone of contract.
The utility model on drill body by being arranged the first rod portion and the second rod portion, and so, this is practical
It is novel to complete the drilling processing of counter sink on product by a drilling operation when carrying out bore operation to product,
Processing so as to the counter sink to product is brought convenience.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present application, constitutes part of this application, this Shen
Illustrative embodiments and their description please are not constituted an undue limitation on the present application for explaining the application.In the accompanying drawings:

In addition, the description for being such as related to " first ", " second " in the present invention is used for description purposes only, and non-specifically
The meaning of order or cis-position is censured, it is also non-to limit the utility model, it is retouched just for the sake of difference with same technique term
The component stated or operation are not understood to indicate or imply its relative importance or implicitly indicate indicated technology
The quantity of feature." first " is defined as a result, the feature of " second " can explicitly or implicitly include at least one spy
Sign.It in addition, the technical solution between each embodiment can be combined with each other, but must be with those of ordinary skill in the art's energy
It is enough realize based on, will be understood that the knot of this technical solution when conflicting or cannot achieve when occurs in the combination of technical solution
Conjunction is not present, also not within the protection scope of the requires of the utility model.
The twolip single flute drill header structure of the utility model, including drill body 1, the right end of drill body 1 are provided with first
Rod portion 11, the middle part of drill body 1 are provided with the second rod portion 12, and the second rod portion 12 connects with the first rod portion 11, the
The outer diameter of two rod portions 12 is greater than the outer diameter of the first rod portion 11, forms step between the second rod portion 12 and the first rod portion 11
Shape structure.
