Description

Technical Field

[0001] The utility model relates to the field of drill bits, in particular to an anti-skid die-cast titanium-plated hexagonal shank twist drill. Background Art

[0002] Most twist drill tips have a narrow V-shaped mouth, and the area of ​​the V-shaped drill tip in contact with the surface to be drilled is limited. Especially on smooth surfaces to be drilled, the drill tip is more likely to slip. Simply increasing the contact pressure between the drill bit and the surface to be drilled will leave marks when the drilling point is not clear, which is not very beautiful. Based on this, this article takes the hexagonal shank twist drill, which currently has a high market share, as an example to improve the slippage problem of hexagonal shank twist drills in a targeted manner. Utility Model Content

[0003] The utility model aims to provide a slip-proof die-cast titanium-plated hexagonal shank twist drill to solve the technical problem.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] An anti-slip die-cast titanium-plated hexagonal shank twist drill, comprising:

[0006] Twist drill, which has a drill point at the end;

[0007] The anti-slip part is used to trap the twist drill and cover the drill tip;

[0008] The anti-slip portion extends outward relative to the drill tip, and the outwardly extending portion contacts the surface to be drilled before the drill tip. In addition, when the twist drill is combined with the drill tip to press the anti-slip portion, the anti-slip portion is divided into two, and then the drill tip contacts the surface to be drilled.

[0009] Preferably, the anti-slip part includes a first half sleeve, a second half sleeve and a connecting rod for connecting the first half sleeve and the second half sleeve, wherein the connecting rod is located below the drill tip and is staggered and crossed with the cross section of the drill tip so that the connecting rod is divided into two when the twist drill is pressed against the anti-slip part.

[0010] Preferably, before the connecting rod is cut off, the first half sleeve and the second half sleeve are close to the twist drill.

[0011] Preferably, the connecting rod is a smooth rod.

[0012] Preferably, the connecting rod is a rod with notches on its surface.

[0013] Preferably, the first half sleeve and the second half sleeve have a plurality of protrusions for increasing friction.

[0014] Preferably, the first half set and the second half set are light transmissive.

[0015] Preferably, the connecting rod is opaque.

[0016] Preferably, the twist drill head has a second hexagonal shank, and the first hexagonal shank is connected to the second hexagonal shank.

[0017] The beneficial effects of the utility model are:

[0018] 1. In the utility model, the connecting rod is located below the drill tip, and the connecting rod and the cut surface of the drill tip are staggered and crossed. In this way, the connecting rod will contact the cut surface before the drill tip of the twist drill, which can avoid the drill tip slipping on the drill surface when the drilling position is not clear. In addition, the connecting rod can be combined with the first half set and the second half set to expand the contact surface of the drill tip, thereby preventing the technical problem of slipping when the drill tip contacts the smooth drill surface.

[0019] 2. In the utility model, after the connecting rod is divided into two, the first half sleeve and the second half sleeve will be away from the twist drill, and will not affect the drilling and cutting work of the twist drill. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0027] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] In this embodiment, a slip-resistant die-cast titanium-plated hexagonal shank twist drill is proposed. Figure 1-Figure 4 The anti-slip die-cast titanium-plated hexagonal shank twist drill comprises a first hexagonal shank 1 , a second hexagonal shank 2 connected to the first hexagonal shank 1 , and a twist drill 3 connected to the second hexagonal shank 2 .

[0030] See also Figure 2 and Figure 3 The twist drill 3 has a drill tip 5 at the end. In this embodiment, the drill tip 5 is covered by an anti-slip portion 4. For details, please refer to Figure 3 and Figure 4 The anti-slip portion 4 includes a first half sleeve 41 , a second half sleeve 43 , and a connecting rod 42 connecting the first half sleeve 41 and the second half sleeve 43 .

[0031] Regarding the connecting rod 42, its surface is smooth and is located below the drill tip 5. In addition, the connecting rod 42 and the cut surfaces of the drill tip 5 are staggered and crossed. In this way, it can be determined that the connecting rod 42 will contact the cut surface before the drill tip 5 of the twist drill 3. Then, the connecting rod 42 is combined with the first half sleeve 41 and the second half sleeve 43 to expand the contact surface of the twist drill 3 and prevent the technical problem of the twist drill 3 slipping when contacting the smooth surface to be drilled.

[0032] Example 2

[0033] In this embodiment, a slip-resistant die-cast titanium-plated hexagonal shank twist drill is proposed. Figure 1-Figure 4 The anti-slip die-cast titanium-plated hexagonal shank twist drill comprises a first hexagonal shank 1 , a second hexagonal shank 2 connected to the first hexagonal shank 1 , and a twist drill 3 connected to the second hexagonal shank 2 .

[0034] See also Figure 2 and Figure 3 The twist drill 3 has a drill tip 5 at the end. In this embodiment, the drill tip 5 is covered by an anti-slip portion 4. For details, please refer to Figure 3 and Figure 4 The anti-slip portion 4 includes a first half sleeve 41 , a second half sleeve 43 , and a connecting rod 42 connecting the first half sleeve 41 and the second half sleeve 43 .

[0035] Regarding the connecting rod 42, it is located below the drill tip 5. In the present embodiment, there is a notch 44 facing the drill tip 5 below the connecting rod 42. The notch 44 can facilitate the extension of the cut of the drill tip 5 into the groove. In this way, the misaligned intersection angle between the connecting rod 42 and the drill tip 5 is fixed, which can limit the deflection of the combination of the first half sleeve 41 and the second half sleeve 43 relative to the drill tip 5, thereby clarifying the cut position.

[0036] Consistent with the first embodiment, in this embodiment, the connecting rod 42 will combine the first half sleeve 41 and the second half sleeve 43 to expand the contact surface of the twist drill 3 and prevent the twist drill 3 from slipping when contacting the smooth surface to be drilled.

[0037] The following contents need to be explained in Example 1 and Example 2:

[0038] ① The first half sleeve 41 and the second half sleeve 43 have a number of protrusions for increasing friction, which can significantly increase the friction with the surface to be drilled and inhibit sliding.

[0039] ② The first half sleeve 41 and the second half sleeve 43 are light-transmissive, while the connecting rod 42 is not light-transmissive. This design, on the one hand, facilitates the positioning of the drilling position, and on the other hand, can be combined with the cross configuration of the connecting rod 42 and the cross section of the drill tip 5 (the center of the intersection is the drilling center) to more accurately position the drilling position.

[0040] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
