How to make the replaced furnace dismantling machine drill bit enter the working state faster

　　1. When drilling a new drill bit, it is necessary to run in at low axial pressure and low rotational speed for 20-30 minutes before gradually increasing to normal axial pressure for use.
　　2. When a new drill bit is opened, attention should be paid to removing debris （such as stones and waste metal） around the hole. During rotation, ventilation should be slow and close to the surface to prevent stuttering and impact damage to the drill bit.
　　3. Before replacing the drill bit with a new one, carefully check whether the three cone wheels rotate flexibly, and whether the threads and teeth are intact.
