Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clear, complete elaboration.
As Figure 1-3, a kind of hole making drill, including drilling rod 1 and cutter hub 2, the mistake cutter groove for connection is provided with drilling rod 1
3rd, drillstock 4 and drill bit 5, cross cutter groove 3 and be opened in the lower section of drilling rod 1, cross the side of cutter groove 3 and offer tightening screw 6, on tightening screw 6
Tight fixed bolt 7 is threaded with, drillstock 4 is welded in the top of drilling rod 1, and drill bit 5 is welded in the bottom of drilling rod 1, and cutter hub 2 was inserted in knife
In groove 3, chip area 8, graduation mark 9 and tightening groove 10 are provided with cutter hub 2, chip area 8 is opened in the lower section of cutter hub 2, and graduation mark 9 is carved
The top of cutter hub 2 is engraved on, tightening groove 10 is opened in the bottom of graduation mark 9.
Specifically used mode：When carrying out perforate to sheet material, cutter hub 2 is arranged in cutter groove 3, required according to perforate, is passed through
The size of the accurate adjustment cutter hub 2 of graduation mark 9, tight fixed bolt 7 is rotated and is screwed into the tightening groove 10 on cutter hub 2 is interior to enter cutter hub 2
Row is fixed, and then drillstock 4 is inserted on the drill chuck of power drill, starts power drill by the drilling sheet material of drill bit 5 to hole making drill
Positioned, with being continuously increased for the drilling depth of drill bit 5, cutter hub 2 carries out scraping to sheet material, and scrap caused by scraping passes through row
Bits groove 8 is quickly discharged outside sheet material.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within the scope of protection of the utility model.
