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. Expanded holes are often used to process holes with diameters smaller than. 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.
