Boring tools are used to process internal holes on the lathe, also known as boring internal holes, so the boring tool for turning the outer circle can be used to expand the internal holes on the lathe. This inner boring process is commonly applied for enlarging existing holes and improving dimensional accuracy during machining. Expanded holes are often used to process holes with larger diameters or improve the accuracy of existing holes. In the drilling of larger diameter holes, often first pre-drilled with a small drill, and then reamed with the corresponding size of the reaming drill, which can improve the quality of the hole processing and production efficiency. In more advanced machining processes, tools such as a spiral hole boring tool may also be used to further enhance hole accuracy and surface finish.
