It is fixedly connected with drill bit with welding manner；The drill bit is prepared from by Hardmetal materials, and it includes 4 cutting edges, and distribution is fixed
Justice is the first cutting edge, the second cutting edge, the 3rd cutting edge and the 4th cutting edge, wherein first cutting edge and the 3rd cutting edge are relative to the brill
The center line of head is symmetrical arranged, and the first cutting edge intersects with the 3rd cutting edge in the side end away from brill body, and forms a spur；
Second cutting edge is symmetrical arranged with the 4th cutting edge, and is vertically arranged relative to the first cutting edge and the 3rd cutting edge.
As preferred version of the present utility model, short slot is offered respectively on second cutting edge and the 4th cutting edge.
Company as preferred version of the present utility model, between the short slot offered on second cutting edge and the 4th cutting edge
Line is vertically arranged relative to the first cutting edge and the 3rd cutting edge.
Used as preferred version of the present utility model, the outer face of the spur is in arc-shaped.
Used as preferred version of the present utility model, the spur is arranged on the center of gravity line of drill bit.
Used as preferred version of the present utility model, the drill bit is fixedly connected in the way of brazing with brill body.
Due to the application of above-mentioned technical proposal, the utility model has the advantages that：
Work cement of building with drill bit is strengthened of the present utility model is bored, and by the way that this to be built the drill bit of work cement brill 4 are set to
The structure of cutting edge, and 4 cutting edges are symmetrical arranged two-by-two, this causes this to build work cement to be drilled in when specifically carrying out drilling operation, just
Felt relieved in the drill bit for building work cement brill, and it is compared existing work of building and bores, it is possible to decrease in manipulation, this builds work to user
It is the moment of torsion to user that cement is bored, and further meets the use demand of people.
Description of the drawings
Fig. 1 is the structural representation for building work cement brill that the band that the utility model preferred embodiment is provided strengthens drill bit.
Fig. 2 is the structural representation of drill bit in the utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit the utility model.
Fig. 1 is referred to, the band that the utility model preferred embodiment is provided strengthens the work cement of building of drill bit and bores 100, including
Drillstock 10, brill body 20 and drill bit 30, on the outer face for boring body 20 screw thread convex tendon 21 is provided with, and is built work cement in order to this and is bored
100 in bore operation, and its brill connection drill bit 30 of body 20 is preferably stretched into treats operation workpiece.Wherein, described one end for boring body 20
Be connected as integral type structure with drillstock 10, the other end is fixedly connected with welding manner with drill bit 30, in the present embodiment its
Preferably it is fixed in the way of brazing between drill bit 30 and brill body 20.
Fig. 2 is referred to, the drill bit 30 builds the punching functional component that work cement bores 100 for this, and it is specifically closed by hard
Golden material is prepared from.In the present embodiment, the drill bit 30 specifically includes 4 cutting edges, for the ease of distinguishing, is respectively defined as
