Horse type bit

Conical drill bits, also known as pneumatic drill bits and rock drilling bits, are used for rock drilling and crushing.Mainly used in coal mines, tunnels, etc. 

It is used in conjunction with B22 rock drill pipe. 

The tapered series bits have simple manufacturing process, convenient regrinding, reliable operation, and strong adaptability to rock mass performance.During drilling operations on concrete, etc., it can alleviate sudden changes in drilling conditions and stabilize drilling operations, and the drilling efficiency will not be reduced even when large chips are generated. 

It is often used with light internal combustion, electric, pneumatic and hydraulic rock drills to drill rock holes with a diameter of less than D50mm in various rocks.Due to its low price and other characteristics, it is still the main drill bit type used in medium and small diameter rock hole drilling projects in my country's mining industry.
