Abstract
The utility model discloses a drill suitable for drilling holes in concrete. The drill comprises a positioning drill, a drill body and a connecting rod, wherein the positioning drill is arranged at the center of the front end of the drill body, the connecting rod is arranged at the rear end of the drill body, a plurality of cutting edges are uniformly welded and embedded at the front end of the drill body, the positioning drill and the drill body (3) are integrated into a whole, two to four chip removing grooves are formed symmetrically at the front end of the drill body and extend backward spirally along the side of the front part of the drill body. Since the positioning drill and the drill body of the drill are of an integrated structure, loosening and breaking off of the positioning drill cannot occur, and chips can be quickly removed through the chip removing grooves in time, thereby improving the drilling speed.
Description
Technical field
The utility model relates to a kind of drilling tool, relates in particular to a kind of hole making drill that is adapted at punching on the concrete.
Background technology
Common hole making drill is made up of drill body, the spitting drill, the connecting rod that are installed on the drill body, and the drill body front end is embedded with drill lip.When this electronic hole making drill is holed, at first get out an aperture, utilize the spitting drill location, rely on the drill lip of drill body front end to leave the hole then with spitting drill.The part but this type of hole making drill also comes with some shortcomings, as in to the perforate process of concrete or wall, occurring the loosening and phenomenon that fractures of spitting drill easily, the scrap that produces in this external perforate process is difficult for getting rid of, and it is poor to influence perforate speed and radiating effect.
Summary of the invention
To the deficiency of above-mentioned prior art, the purpose of the utility model provides a kind of hole making drill that is adapted at punching on the concrete.
To achieve these goals, the technical scheme of the utility model employing is such: a kind of hole making drill that is adapted at punching on the concrete comprises spitting drill, drill body, connecting rod; Spitting drill is arranged on drill body front end center; Connecting rod is arranged on the drill body rear end, and said drill body front end welds equably and studs with some cutting edges, and said spitting drill and drill body are conjuncted; The front end symmetry of drill body offers two to four chip removal grooves, and the chip removal groove extends along the drill body toe lateral towards the rear screw shape.Loosening and the phenomenon that fractures of spitting drill can not appear in such setting, and the chip removal groove that the drill body front end is offered can in time be got rid of scrap apace.
Said drill body and connecting rod also are provided with the locking platform for being threaded on the sidewall of drill body.
The tail end cross section of said connecting rod is regular hexagon.
Compared with prior art, the advantage of the utility model is: the spitting drill of this hole making drill and drill body are conjuncted structure, the loosening and phenomenon that fractures of spitting drill can not occur, and the chip removal groove can in time be got rid of scrap apace, has improved perforate speed.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1, the hole making drill that is adapted at punching on the concrete of the utility model comprises spitting drill 1, drill body 3, connecting rod 4; Spitting drill 1 is arranged on drill body 3 front end centers, and connecting rod 4 is arranged on drill body 3 rear ends, and said drill body 3 front ends weld equably and stud with some cutting edges 6; Said spitting drill 1 is conjuncted with drill body 3; The front end symmetry of drill body 3 offers two chip removal grooves 2, and chip removal groove 2 extends along drill body 3 toe lateral towards the rear screw shape, and said drill body 3 and connecting rod 4 are for being threaded; On the sidewall of drill body 3, also be provided with locking platform 5, the tail end cross section of said connecting rod 4 is regular hexagon.
