Description

When using a three cone drill bit, it is necessary to follow the standard operating procedures. For example, it is necessary to choose the appropriate rotational speed to ensure the effectiveness and safety of drilling. For different materials, there are different optimal speed ranges, and the best effect can be achieved by adjusting the speed of electric tools. During the drilling process, appropriate pressure needs to be applied to maintain stability. Excessive pressure may cause the drilling process to be slow or even stuck, while insufficient pressure may affect the effectiveness of drilling.
