What does the pilot hole mean?

Lead-in hole refers to a small hole to lead out wires, pipes and other lines when it is necessary to cross structural members such as walls and floors in engineering projects. The size of the pilot hole usually depends on the size of the pipeline to ensure the smoothness and safety of the pipeline. In building engineering, hole drilling is a very common technology, which is mainly used in hydropower, HVAC, ventilation and so on.

Guide holes sometimes refer to small holes dug in the production of wood products, which are used to fix nails or other parts to achieve overall stability. Such as making furniture, splicing boards, etc. Hole introduction treatment is usually required. In the traditional manual process, hole introduction is also considered as a skill, which requires certain skills and experience to achieve lossless or zero-error hole introduction.

Pilot holes are very common in modern manufacturing industry. It is necessary to manufacture complex parts in industrial production, and it is easy to manufacture complex internal structures and obtain better performance by using hole guide technology. In addition, modern science and technology have also improved and innovated the hole-leading technology, such as laser drilling technology and electron beam etching technology, which has a broader application prospect in miniaturization, high precision and high efficiency.
