[0002] The drill bit is mainly used to drill through holes or blind holes in solid materials, and can expand existing holes. The drill bit rotates and moves centripetally, and uses cutting and grinding to crack and break rocks or materials, thereby forming the required holes. It is an important tool in engineering operations and is widely used in various drilling and oil drilling scenarios.

[0003] During the drilling process, the existing drill bits can usually only meet the drilling requirements of fixed sizes. For drilling holes of different sizes or materials, drill bits of different specifications need to be replaced, which increases the complexity of the work and reduces work efficiency.
