Many people need to drill one step and then two steps when processing large holes and countersunk holes. This process is cumbersome, and manual operation is easy to make mistakes, resulting in unnecessary economic losses. The step drill breaks through the traditional processing process, allowing the large and small holes to be processed at one time. In the case of high labor costs today, the punching time is saved and the drilling efficiency is improved, which is an ideal tool for large-scale engineering batch drilling. Suitable for woodworking drilling rigs, drilling rigs, hand drills, etc.
