Abstract

The utility model discloses a chip removal anti-winding drill bit which comprises a drill bit body. The drill bit is provided with at least two chip grooves; cutting teeth are arranged in the chip grooves, are in central symmetry along the axis, are in a sharp corner shape and are provided with two cutting edges, and the multiple sets of cutting teeth extend from the head of the drill bit to the tail of the drill bit at intervals in a spiral mode. The cutting-off teeth are arranged in the chip discharging groove, the cutting-off teeth can cut long-strip wood chips passing through the cutting-off teeth, the multiple sets of cutting-off teeth can sequentially cut the wood chips from bottom to top, and therefore short wood chips are discharged out of holes and prevented from winding a drill bit.

Description

Technical Field

[0001] The utility model belongs to the technical field of drill bits, and in particular relates to a chip removal and anti-winding drill bit. Background Art

[0002] The furniture wood industry often requires drilling, which is usually done with a drill press or handheld electric drill. The wood chips discharged from drilling the board will be in long strips and entangled on the drill bit, seriously affecting the quality and processing operation of the drilling process. When too much wood chips entangle the drill bit, it is necessary to stop the machine for cleaning, which seriously affects the processing efficiency. Therefore, it is necessary to further enhance the chip breaking effect of the drill bit to prevent the chips from entangled on the drill bit. Utility Model Content

[0003] In view of this, the technical problem to be solved by the utility model is to provide a chip removal and anti-entanglement drill bit, which solves the problem that wood chips are easily entangled in the drill bit in the prior art.

[0004] In order to solve the above technical problems, the utility model discloses a chip removal and anti-entanglement drill bit, comprising: a drill bit; the drill bit has at least two chip removal grooves; cutting teeth are arranged in the chip removal grooves, the cutting teeth are symmetrical along the axis center, the cutting teeth are pointed, and have two cutting edges, and multiple groups of cutting teeth extend from the drill head to the tail at spiral intervals.

[0005] Furthermore, the cutting teeth are flat, and two side surfaces are curved, with a cutting edge formed where the two side surfaces meet.

[0006] Furthermore, one of the cutting blades has an arc-shaped edge.

[0007] Furthermore, cutting teeth are arranged at 90° intervals in a spiral direction from the head to the tail of the drill bit.

[0008] Furthermore, the above-mentioned cutting teeth form an angle of 30° with the radial axis of the drill bit.

[0009] Compared with the prior art, the present application can obtain the following technical effects:

[0010] The utility model arranges cutting teeth in the chip removal groove, the cutting teeth can cut the long wood chips passing through, and the multiple groups of cutting teeth can cut the wood chips in sequence from bottom to top, so that the short wood chips are removed from the holes to prevent winding around the drill bit.

[0011] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The drawings described herein are used to provide a further understanding of the present application and constitute a part of the present application. The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute an improper limitation on the present application. In the drawings:

[0017] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a drill bit according to one embodiment of the utility model; Figure 2 It is a bottom view of a drill bit according to one embodiment of the present invention.

[0019] A chip removal and anti-entanglement drill comprises: a drill 1; the drill has at least two chip removal grooves 2; a cutting tooth 3 is arranged in the chip removal groove 2, the cutting tooth 3 is symmetrical along the axis center, the cutting tooth 3 is pointed, and has two cutting edges 4, and three groups of cutting teeth 3 extend from the head of the drill 1 to the tail at a spiral interval.

[0020] The cutting teeth 3 are flat, and the two side surfaces thereof are curved, which reduces the friction between the wood chips and the surface of the cutting teeth 3, and facilitates the wood chips to pass through the two edges of the cutting teeth 3, and the edges are formed at the junction of the two side surfaces; one of the cutting edges is in an arc shape; the cutting teeth 3 are arranged at 90° intervals in a spiral from the head to the tail of the drill bit 1; the cutting teeth 3 form an angle of 30° with the radial axis of the drill bit 1, and the inclined cutting teeth 3 can facilitate the passage of wood chips, and the cutting of wood chips is also smoother.

[0021] In summary, the utility model provides cutting teeth 3 in the chip removal groove 2, and the cutting teeth 3 can cut the long wood chips passing through, and multiple groups of cutting teeth can cut the wood chips from bottom to top in sequence, so that the short wood chips are excluded from the holes to prevent them from winding around the drill bit.

[0022] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
