Description of drill bit classification

Threaded top hammer bit:Jingzuan Co., Ltd. is a professional enterprise engaged in the research of rock drilling tools. The supplied rock drilling tools, down-the-hole drilling tools and mining machine tools are widely used in basic energy construction fields such as mountain excavation, mining, railways, highways, hydropower, etc..Its products mainly include the following:

1. Taper products: flat bit (drill), cross bit, button bit, hexagonal bit (H22Drill rod)

2. Overall drill: rod diameterH19,H22, Head diameter:2042mm;

3. Threaded connection drilling tools: (R22,R25,R28,R32,R38,T38,T45,T51Thread)

Threaded button bit (drill), flat type, concave core type, easy return type, easy return concave type (diameter51127mm)

Connection sleeve and reducing connector: (R22,R25,R28,R32,R38,T38,T45,T51)

Shank tail: (R32,R38,T38,T45,T51Thread, etc., can be with At las Copco, Furukawa, Ingersoll RandSupporting by well-known foreign companies).

Drill pipe:R25,R28,R32,R38,T38,T45,T51Various specifications of threaded drill bits and male and female threaded drill rods

Column tooth bit:Spherical tooth series bit passivation has a long service life, and its non-grinding life is about that of the same diameter blade bit bit.5-6Times, it is helpful to save auxiliary working hours, reduce workers' physical labor and speed up construction.

1.Down-the-hole drill

Down-the-hole drillIt is a kind of drill bit used with DTH impactor,Drilling through the spline and impactor,Widely used in open pit mining,quarry,Hydropower Engineering,Drilling of water wells,Excavation side pillar support, etc..It is divided into:Low pressure DTH drill bit,Medium and high wind pressure submersible drill bit. DTH drill bit and DTH impactor used together,With drilling straight,high speed,Features of drilling deep holes.So it has been widely used in recent years.

2.Threaded stud bit

The threaded connection column teeth are mainly connected with hydraulic rock drills(Or pneumatic rock drill)And hydraulic drill rod(Pneumatic drill rod)A matching drill bit,Match with drill rod through different forms of thread,Perform drilling operations,Drill diameter from 32-203mm,Mainly used in the mining of underground mines,Open pit mining,Blast furnace openings in steel mills and other fields.high speed,Convenient for grinding.
