[0002] A drill bit is a tool used to drill holes in various materials. It is usually made of steel and has a sharp cutting edge that can remove material and form a hole through a rotating action. The design and use of drill bits vary. Common drill bit types include diamond drill bits, metal drill bits, woodworking drill bits, drilling blades, etc. In daily use, they are usually used with tools such as electric drills, manual rotary tools, and drill presses. Most drill bits are one-piece and are usually produced into predetermined shapes and sizes through processes such as cutting, milling, and grinding.

[0003] At present, workers drill holes in processed objects by hand-held electric drills or rotating tools. The drilling angle is controlled by the workers themselves, and the drilling angle needs to be constantly corrected during the drilling process to avoid the holes being too large or the angles deviating. When drilling workpieces with complex operating environments, it is particularly difficult to manually change the drilling angle, which may cause the construction period to stagnate, or even the workpieces have to be dismantled for drilling separately, and then assembled after the drilling is completed, which is time-consuming, labor-intensive and costly.
