Piece, the linear structural arrangement of composite sheet, first bit head, the second bit head, third bit head and the 4th bit head
Outer circumference surface be arranged in smooth convex structure.
Further, the composite sheet is diamond compact, first bit head, the second bit head, third drill bit
It is equipped in composite sheet in portion and the 4th bit head and is equipped with 3 groups of composite sheets.
Further, the trapezoidal structure setting in upper square section of the shank, the lower section of the shank are in cylindrical structure
Setting.
Further, the top of the shank is equipped with 4 groups of circular holes, and angle is equal between the circular hole.
Further, the top of the shank is equipped with protrusion, and the protrusion is equipped with two groups, and be centrosymmetric structure setting.
Further, the composite sheet is arranged in cylindrical structure.
Further, first bit head, the second bit head, third bit head and the 4th rounded array junctions of bit head
Structure setting.
Invention compared with prior art the advantages of be: a kind of NEW TYPE OF COMPOSITE piece drill bit of the present invention efficiently solves existing
The problem of technology, has many advantages, such as excellent wear-resisting property, practical；The first bit head, the second brill in the present invention
