Technical Field

[0001] The utility model belongs to the technical field of tooth implant drilling equipment, and more specifically relates to a side cutting drill. Background Art

[0002] Dental implants are a common occurrence in modern life. The implant process often requires drilling a hole in the mouth. This process is typically performed using a drill bit, which consists of a drill rod and a cutting edge attached to the rod. The cutting edge drills the hole as the rod rotates. However, existing cutting edges can only cut in one position as the rod rotates, resulting in low cutting efficiency.

[0003] The drill bit can refer to the cutter head in (China Invention Patent; Publication Number: CN117017536A; Subject Name: Dental Implant Positioning Assembly and Positioning Method Thereof; Publication Date: 2023-11-10). Utility Model Content

Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0028] It should be noted that the term "plurality" means two or more, unless otherwise clearly defined.

[0029] Please also refer to Figures 1 to 4 The side-cutting drill provided by the present invention is now described. The side-cutting drill comprises a drill rod 1 and a blade 2 provided on the drill rod 1. The blade 2 comprises a plurality of blades 21 sequentially arranged along the drill rod 1. The plurality of blades 21 are arranged in a zigzag pattern.

[0030] Thus, a blade 2 is provided on the drill rod 1. The blade 2 comprises a plurality of blades 21 arranged in a serrated pattern along the drill rod 1. Each blade 21 can cut the external workpiece as the drill rod 1 rotates, thereby improving processing efficiency. Furthermore, the serrated arrangement of the blades 21 allows the cut material to be discharged through the gaps between the teeth, and heat is also more easily dissipated from the teeth.

[0031] Further, see Figures 1 to 4 As a specific embodiment of the side cutting drill provided by the present invention, the number of blades 2 is multiple. In this way, multiple blades 2 can improve the cutting ability.

[0032] Further, see Figures 1 to 4 In a specific embodiment of the side-cutting drill provided by the present invention, a plurality of blades 2 are sequentially arranged around a drill rod 1. In the direction around the drill rod 1, any two adjacent blades 2 are spaced apart. This facilitates the discharge of chips along the gaps between adjacent blades 2.

[0033] Further, see Figures 1 to 4 As a specific embodiment of the side cutting drill provided by the present invention, each blade 2 is spirally wound around the outer surface of the drill rod 1. In this way, the chips are easily discharged along the gaps between adjacent blades 2.

[0034] Further, see Figures 1 to 4 As a specific embodiment of the side cutting drill provided by the present invention, a colored mark 3 is arranged on the drill rod 1. In this way, the user can judge the drilling depth of the drill rod 1 by the colored mark 3.

[0035] In one embodiment, the colored mark 3 is a coating layer having color and coated on the drill rod 1 .

[0036] In one embodiment, the color of the colored marking 3 is different from the color of the drill rod 1 .

[0037] Further, see Figures 1 to 4 As a specific embodiment of the side-cutting drill provided by the present invention, a plurality of colored markings 3 are arranged on the drill rod 1; the plurality of colored markings 3 are arranged sequentially along the drill rod 1. In this way, the user can more conveniently judge the different depths of the drill rod 1 by the plurality of colored markings 3.

[0038] Further, see Figures 1 to 4 As a specific embodiment of the side-cutting drill provided by the present invention, any two adjacent colored marks 3 are spaced apart in the extension direction of the drill rod 1. In this way, the spaced colored marks 3 make it easier to judge the different depths of the drill rod 1.

[0039] Further, see Figures 1 to 4As a specific embodiment of the side-cutting drill provided by the present invention, each blade 21 includes a left blade portion 211 for cutting the sidewall of the hole to be machined when the drill rod 1 rotates in one direction, and / or a right blade portion 212 for cutting the sidewall of the hole to be machined when the drill rod 1 rotates in the other direction. Thus, the left blade portion 211 can cut when the drill rod 1 rotates in one direction, and / or the right blade portion 212 can cut when the drill rod 1 rotates in the other direction.

[0040] Further, see Figures 1 to 4 As a specific embodiment of the side cutting drill provided by the present invention, each blade 21 further includes: a lower blade portion 213 for cutting the inner wall of the hole to be processed below when the drill rod 1 moves downward. In this way, the drill rod 1 can be cut by the lower blade portion 213 when it moves downward.

[0041] Further, see Figures 1 to 4 In a specific embodiment of the side-cutting drill provided by the present invention, the bottom end of the drill rod 1 has a protective portion 11; each blade 21 is located above the protective portion 11. In this way, when the drill rod 1 moves downward, the protective portion 11 at the bottom of the drill rod 1 can prevent the blade 21 from cutting the bottom wall of the hole to be processed.

[0042] In one embodiment, the drill rod 1 extends in a vertical direction.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
