Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As shown in Figures 1 to 5, this depth drill includes that matrix, described matrix include the connecting portion 110 of truncated cone-shaped, from connection
The front end in portion 110 has convexed to form columned installation portion 120, has convexed to form knife bar portion 130 from connecting portion 110 rear end.
Preferably, the outer surface of columned installation portion 120 offers the installed surface 121 tangent with installation portion 120,
Facilitate this utility model to be installed on equipment, improve the steadiness that this utility model is installed.
Further, installation portion 120 offers escape 122 near connecting portion 110 side, facilitates adding of installation
Work, offers cannelure 123 away from connecting portion 110 side on installation portion 120, and in installation process, this utility model can pass through
Cannelure 123 is installed on fixture, it is ensured that the steadiness that this utility model is connected between the two with fixture, it is to avoid using
Journey occurs the generation of position shift phenomenon.
Knife bar portion 130 offer relatively and the first chip area 131 and the second chip area 132 of arranging of spiral, first
Chip area 131 and the second chip area 132 all extend to connecting portion 110 from the end in knife bar portion 130 so that make at this utility model
During with, chip can discharge respectively along the first chip area 131 and the second chip area 132, thus avoids chip to cause
The generation of clogging, improves work efficiency of the present utility model.
The end face in knife bar portion 130 offers the bar-shaped trough 133 for installing drill, is provided with in bar-shaped trough 133
