At present, there are four main design forms of DDRI bit: convex face, flat face, concave face and deep concave face center face.
Ball tooth, spring tooth or ball tooth and spring tooth are selected for cemented carbide.
It is mainly divided into the following categories:
1. DTH bit bit is a kind of drill bit which is used with DTH hammer. It is widely used in mining of open pit mine, quarry, hydroelectric engineering, drilling of water well, and supporting of side pillar of excavation, etc.
It is divided into: low pressure drill hole drill bit, medium and high wind pressure drill hole drill bit.
The drill bit of the drill column is used in cooperation with the drill impacter, which has the characteristics of straight drilling, fast drilling speed and deep drilling.
So in recent years, it has been widely used.
2. Thread connection column tooth bit thread connection column tooth primarily with hydraulic rock drill (or pneumatic rock drill) and hydraulic drill rod () pneumatic drill rod supporting the use of a drill, cooperate through different forms of thread and drill rod and perforating operations, and bit by ￠32 - ￠203 mm in diameter, is mainly used in the mining of underground mining in open-pit mine mining, steel blast furnace openings, etc.
Fast speed, convenient grinding.
3. Taper joint column bit bit is mainly used with pneumatic drill and taper bar matching a drill bit, through the taper and drill bar connection, drilling operations, mainly used in the mine secondary crushing, bolt support, roadway excavation and other fields.
The cylindrical drill bits produced by our company are designed according to ISO international standards.
