Abstract
The utility model discloses a saw-type trepanning drill, which is composed of a vertical type circular saw and a positioning drill. The vertical type circular saw forms cylinder shape; the end face of the cylinder mouth is provided with saw teeth; the side face of the circular saw is provided with a scrap discharging hole; the bottom face of the circular saw is provided with a material discharging hole; the center of the bottom face is provided with a positioning screw hole. The positioning drill is composed of the drill tip of the head part, the screw bolt of the middle part and the connecting rod of the hand held electric drill of the tail part. The positioning drill can be screwed in the central positioning screw hole of the bottom face of the vertical type circular through the screw bolt of the middle part. The drill tip part of the positioning drill can extend out of the cylinder mouth vertical type circular saw. The utility model has the advantages of simple structure and easy manufacture, and is suitable for hole drilling and installation of door locks, drawer locks and aluminium alloy door locks.
Description
The utility model relates to a kind of tool for cutting machining, is a kind of multipurpose saw formula trepanning drill specifically.
Traditional drilling method is generally all used spiral bit, because the spiral bit diameter is limited, so when needing to bore than macropore, hole with suitable spiral bit earlier, expands and several procedures such as file just can be finished again.
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and increases work efficiency, and reduces labor intensity, and collection bores, expands, files one step completed saw formula trepanning drill.
To achieve these goals, the utility model adopts following technical scheme: a kind of saw formula trepanning drill, it is characterized in that: it is made up of vertical circular saw and spitting drill, this vertical circle is sawn into cylindric, the end face of its nozzle is a sawtooth, the side is provided with discharging opening, the bottom surface is provided with discharge opening, the center of bottom surface is provided with the set screw hole, this spitting drill is by the apex point of head, the bolt at middle part and the electric hand drill connecting rod of afterbody are formed, this spitting drill screws in the centralized positioning screw hole of this vertical circular saw bottom surface by the bolt at this middle part, and this vertical circular saw nozzle stretches out in the apex point portion of this spitting drill.
Good effect of the present utility model is: simple in structure, easily make, and easy to use, several procedures such as collection brill, expansion, file are once finished, thereby can reduce labor intensity, increase work efficiency.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the structural representation of a preferred embodiment of the utility model;
Fig. 2 is that the vertical circular saw of a preferred embodiment of the utility model partly cuts open structural representation;
Fig. 3 is the spitting drill structural representation of a preferred embodiment of the utility model.
Seeing also Fig. 1, Fig. 2 and shown in Figure 3, is preferred embodiment of the utility model.It is made up of vertical circular saw 10 and spitting drill 20, this vertical circle is sawn into cylindric, the end face of its nozzle 15 is that sawtooth 11, side are provided with the center that discharging opening 12, bottom surface be provided with discharge opening 13, bottom surface set screw hole 14 is set, this spitting drill is made up of the apex point 21 of head, the bolt 22 at middle part and the electric hand drill connecting rod 23 of afterbody, this spitting drill screws in the centralized positioning screw hole of this vertical circular saw bottom surface by the bolt at this middle part, and this vertical circular saw nozzle stretches out in the apex point portion of this spitting drill.The utility model is applicable to timber cylinder drawback lock, ball catch, drawer-lock, uses when more can be used for all kinds lockhole such as aluminium alloy door lock by dress boring.
