Sword grinds the first shear blade relief angle and the second shear blade relief angle for having 3 ° on the end face of shear blade side, and the first shear blade relief angle is located at
Cutting edge end face is provided with positioning core, the positioning core and cutting far from auger spindle one end close to shear blade side, the drill body
Mill has knuckle between sword and between cutting edge end face and auger spindle.
As a kind of optimal technical scheme of the utility model, the cutting edge is that the first shear blade relief angle is formed with chip space
Tip-angled shape blade.
As a kind of optimal technical scheme of the utility model, the shear blade is vertical with auger spindle.
As a kind of optimal technical scheme of the utility model, the auger spindle is changed by reamer core entity to be ground.
As a kind of optimal technical scheme of the utility model, the auger spindle is an integral molding structure with cutting edge.
As a kind of optimal technical scheme of the utility model, the positioning core is an integral molding structure with cutting edge.
Compared with prior art, the utility model has the beneficial effects that：This kind of reamer restructures counterbit, passes through drill body one end
Grind knuckle, shear blade and shear blade relief angle so that restructuring after tool in cutting sword it is more sharp, and cutter have again preferably it is tough
Property, so that tool feeding speed is fast, cutting stabilization is not easy tipping, substantially increases the processing efficiency of workpiece, and workpiece table
Surface roughness is preferable, and since drill body is restructured using discarded reamer, the production is simple and convenient, greatly reduces the production of counterbit
Cost, and discarded reamer is recycled, be conducive to economize on resources.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of reamer restructures counterbit, including drill body 1, cuts
It cuts sword 2, chip space 3, the first shear blade relief angle 4, the second shear blade relief angle 5, knuckle 6, auger spindle 7, shear blade 8, shear blade anterior angle 9 and determines
Position fuse 10, for drill body 1 using being restructured using the waste and old reamer of rear curtailment, 1 one end of drill body is provided with auger spindle 7, bores
Multiple cutting edges 2 are provided on body 1, in the shape of a spiral, cutting edge 2 is provided with shear blade 8, cutting edge close to 7 one end of auger spindle to cutting edge 2
2 are provided with shear blade anterior angle 9 close to 8 side of shear blade, form chip space 3 between two shear blade anterior angles 9, cutting edge 2 is close to shear blade 8 one
Mill has 3 ° of the first shear blade relief angle 4 and the second shear blade relief angle 5 on the end face of side, and the first shear blade relief angle 4 is located at 2 end face of cutting edge and leans on
Nearly 8 side of shear blade, drill body 1 are provided with positioning core 10 far from 7 one end of auger spindle, between positioning core 10 and cutting edge 2 and cut
It cuts to grind between 2 end face of sword and auger spindle 7 and has knuckle 6.
Cutting edge 2 is the tip-angled shape blade that the first shear blade relief angle 4 is formed with chip space 3, and shear blade 8 is vertical with auger spindle 7, auger spindle
7 are changed by reamer core entity and grind, and auger spindle 7 is an integral molding structure with cutting edge 2, and positioning core 10 is with cutting edge 2
