Introduction of Top Hammer Drill Bits

1. What is top hammer drill bit?

Top hammer threaded drill bit is a kind of threaded bit for hard rock drilling, generally suitable for quarry, open pit mining, underground mining, engineering construction, highway and hydropower and other working environments.

The top hammer threaded drill bit is used in conjunction with the drill rod, shank adapter, and rock drill to be installed on the hydraulic drill rig to provide rock drilling impact force. Top hammer drill bits can be used in all types of soft and hard rock, and when there is an air gap in the rock, it needs to drill slowly, pushing the rig into a longer distance with each impact.

Commonly used thread forms are: rope thread (R25, R28, R32, R35, R38) and trapezoidal thread (T38, T45, T51).

2. What are the characteristics of top hammer drill bits?

The characteristics of top hammer rock drill bits are strong wear resistance, good impact resistance, high hardness and good self-sharpening. Made of cemented carbide, through good processing technology and drill bit face design, the service life, perforation efficiency and supply rate of the top hammer thread drill bit can be improved.

The top hammer threaded drill bit adopts cemented carbide, and it can improve the service life, piercing efficiency and supply rate through good processing technology and drill face design.
