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 6, this modified model depth drill includes that matrix, described matrix include that shape is the connection of truncated cone-shaped
Portion 110, front end from connecting portion 110 convex to form columned installation portion 120, convex to form from connecting portion 110 rear end
Knife bar portion 130, offers the first chip area 131 and the second chip area 132 being oppositely arranged in knife bar portion 130, and described first
Chip area 131 and the second chip area 132 extend to connecting portion 110 from the end in knife bar portion 130 so that use at this utility model
During chip can discharge respectively along the first chip area 131 and the second chip area 132, thus it is stifled to avoid chip to cause
The generation of plug phenomenon, improves work efficiency of the present utility model.
The lower surface in knife bar portion 130 offers the installing hole for installing drill 200, in installing hole, is provided with brill
Cutter 200 and drill 200 energy realizing self disassembling, facilitate the replacing when drill 200 abrasion occurs or collapses cutter phenomenon, improve brill
The replacing efficiency of cutter 200.
Preferably, matrix offers the fixing hole 150 running through matrix and communicating with installing hole, outside drill 200
Offer the confined planes 241 corresponding with fixing hole 150 on surface, in fixing hole 150, be provided with holding screw and described tightening
Screw is through fixing hole 150 being resisted against on confined planes 241, it is ensured that the steadiness that drill 200 is installed, it is to avoid in drill
During 200 work, drill 200 occurs that position skew affects the generation of the work efficiency phenomenon of drill 200, improves brill
