The drill bit comprises a drill handle and a drill body, wherein a drill tip is formed at one end, far away from the drill handle, of the drill body, the drill tip comprises a main cutting edge and an auxiliary cutting edge, a spiral chip groove is formed on an extending surface of the auxiliary cutting edge and extends towards the direction of the drill handle, a left inclined step surface and a right inclined step surface which correspond to each other are arranged between the drill body and the drill tip, the inclined step surfaces on the two sides are arranged by taking the drill tip as the center, a plurality of inclined plane notches are arranged at the joint positions of the inclined step surfaces and the spiral chip groove, and the inclined plane notches are connected with the spiral chip groove.
The utility model is further improved in that: the inclined plane notches are arranged at the joint of the inclined step surface and the spiral chip groove at equal intervals.
The utility model is further improved in that: the inclined step surface and the horizontal plane form an included angle of 45 degrees +/-15 degrees.
The utility model is further improved in that: the outer diameter of the drill body is the same as that of the drill handle.
The utility model is further improved in that: the inclined plane gap is of a triangular polished surface structure.
The utility model is further improved in that: and a flow guide plane is arranged at the position of the spiral chip groove far away from the drill tip.
The utility model is further improved in that: the bottom of the drill handle is provided with a conical convex grinding surface.
The utility model has the beneficial effects that:
set up the drill point can carry out the location in hole earlier before product processing, then the rethread the work that the body of boring carried out drilling sets up the drill point can prevent skidding of the in-process of punching to can effectively improve the oblique problem of hole site, and improve the precision of punching, set up a plurality of simultaneously on the sloping step surface the inclined plane breach can effectively reduce the temperature of sloping step surface has improved the incorruptibility of drill bit, is in at last the end of heliciform chip groove is provided with water conservancy diversion planar structure for the chip removal is more smooth and easy, can also reduce the high temperature that produces in the course of working rapidly.
