Technical Field

[0001] This utility model relates to the field of flat-head drill bits, specifically a coated multifunctional flat-head drill bit. Background Technology

[0002] Flathead drill bits are a common type of drill bit, primarily used for drilling holes in wood. The flathead drill bit has a flat center, a design that allows it to effectively cut and quickly remove sawdust during drilling, ensuring both drilling quality and efficiency. Common sizes for flathead drill bits range from 6 to 25 millimeters, meeting the drilling needs of most woodworking projects.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] like Figures 1-4As shown, this embodiment provides a coated multifunctional flat-head drill, including a flat-head drill rod 1. A cutting edge 2 is formed on the outer surface of the flat-head drill rod 1. A lifting layer 3 is connected to the outer surface of the flat-head drill rod 1. The lifting layer 3 includes a first hardness-increasing layer 301, a first toughness layer 302, a first rust-resistant layer 303, a second hardness-increasing layer 304, a second toughness layer 305, a second rust-resistant layer 306, a third hardness-increasing layer 307, a third toughness layer 308, and a third rust-resistant layer 309. One end of the flat-head drill rod 1 has a set of auxiliary opening grooves 4. Through the cutting edge 2 and the auxiliary opening grooves 4, drilling can be conveniently performed and drilling efficiency can be improved. This is combined with the first hardness-increasing layer 301, the second hardness-increasing layer 304, and the third hardness-increasing layer 307. The first hardness-increasing layer 301 is tungsten, the second hardness layer 305, and the third hardness layer 306. The first layer 304 is vanadium, and the second layer 307 is manganese. These layers improve the strength of the flat-head drill rod 1, preventing it from breaking easily. The third layer 308 consists of a first toughness layer 302, a second toughness layer 305, and a third toughness layer 308. The first toughness layer 302 is PEEK resin, the second toughness layer 305 is a chromium-cobalt-nickel alloy, and the third toughness layer 308 is chromium-molybdenum-vanadium powder high-speed steel. This improves the torque resistance of the flat-head drill rod 1. In conjunction with the first rust-resistant layer 303, the second rust-resistant layer 306, and the third rust-resistant layer 309, the first rust-resistant layer 303 is a nano-coating, the second rust-resistant layer 306 is Teflon, and the third rust-resistant layer 309 is an LDC diamond film. This enhances the rust resistance of the flat-head drill rod 1, preventing rust from appearing and affecting its service life.

[0024] In this embodiment, the outer surface of the first hardness-enhancing layer 301 is fixedly connected to the inner wall of the first toughness layer 302, and the outer surface of the first toughness layer 302 is fixedly connected to the inner wall of the first rust-resistant layer 303. This improves the connection stability between the first hardness-enhancing layer 301 and the first toughness layer 302. The outer surface of the first rust-resistant layer 303 is fixedly connected to the inner wall of the second hardness-enhancing layer 304, and the outer surface of the second hardness-enhancing layer 304 is fixedly connected to the inner wall of the second toughness layer 305. This increases the hardness of the second hardness-enhancing layer 304 and the second toughness layer 305. The stability of layer 5 is achieved by fixing the outer surface of the second toughness layer 305 to the inner wall of the second rust-resistant layer 306, fixing the outer surface of the second rust-resistant layer 306 to the inner wall of the third hardness-increasing layer 307, thereby increasing the tightness of the second rust-resistant layer 306 and the third hardness-increasing layer 307, fixing the outer surface of the third hardness-increasing layer 307 to the inner wall of the third toughness layer 308, and fixing the outer surface of the third toughness layer 308 to the inner wall of the third rust-resistant layer 309, thereby improving the firmness of the third toughness layer 308 and the third rust-resistant layer 309.

[0025] In this embodiment, each auxiliary opening slot 4 is located at the bottom end of the flat-head drill rod 1. The first hardness-increasing layer 301 is tungsten, the second hardness-increasing layer 304 is vanadium, and the third hardness-increasing layer 307 is manganese, which can increase the hardness of the flat-head drill rod 1. The first toughness layer 302 is PEEK resin, the second toughness layer 305 is chromium cobalt nickel alloy, and the third toughness layer 308 is chromium molybdenum vanadium powder high-speed steel, which can improve the toughness of the flat-head drill rod 1. The first rust-resistant layer 303 is a nano-coating, the second rust-resistant layer 306 is Teflon, and the third rust-resistant layer 309 is LDC diamond film, which can prevent the flat-head drill rod 1 from rusting and increase its service life.

[0026] Working principle: First, the cutting edge 2 and the auxiliary opening groove 4 can provide drilling and auxiliary opening for the flat-head drill rod 1. The first hardness increasing layer 301, the second hardness increasing layer 304 and the third hardness increasing layer 307 can increase the hardness of the flat-head drill rod 1. At the same time, the first toughness layer 302, the second toughness layer 305 and the third toughness layer 308 can provide the flat-head drill rod 1 with high toughness and torque. In addition, the first rust-resistant layer 303, the second rust-resistant layer 306 and the third rust-resistant layer 309 can provide the flat-head drill rod 1 with high rust resistance. The above is the complete usage process of this utility model.
