As a category of rock drilling tools, the threaded drill bits are mainly used for drilling blast holes. During drilling operation, the drill string consisting of drill bits, drill rods, coupling sleeves and shank adapters transmits the impact energy of rock drills to the drill bits for directly drilling the rock. The threaded drill bits have the characteristics of reliable connection and high transfer efficiency, and are mainly used with rock drills with high frequency and impact power for underground tunneling, rock bolting, surface mining, tunnel construction, quarrying, etc.
