Abstract
The utility model discloses a drill bit capable of removing burrs. The drill bit comprises a drill bit body, wherein a burr cutter is fixedly arranged on the outer wall of the upper end of the drill bit body; the burr cutter and the drill bit body are fixedly installed on a cutter handle; the sharp end of the drill bit body is provided with a plane; moreover, a square hole is formed in the plane; a spring is fixedly arranged on the internal bottom part of the square hole; the outer end of the spring is connected onto a positioning rod; the lower end of the positioning rod is provided with a flat positioning cutter; the positioning rod and the positioning cutter are connected by a magnet. The drill bit is simple in structure and easy to realize; as an elastic auxiliary positioning cutter is arranged on the cutter head, a preliminary positioning function can be realized by using the elastic auxiliary positioning cutter; therefore the drill bit can be effectively prevented from suffering from an excursion or damage problem; moreover, at the time of punching, burrs at the opening of the hole can be removed, so that the use range of the drill bit is expanded.
