Column tooth with traditional flake chisel bit chisel bit compared with the grinding cycle is long, cut speed characteristics of drilling. Mainly divided into the following categories:
1. The chisel bit steep dive gear
Chisel bit steep dive gear is and DTH impact is supporting the use of a drill, and through the spline and impact with the drilling, widely used in open-pit mine mining, the quarry, hydropower engineering, the well drilling, excavation side pillar support, etc. Which is divided into: low voltage chisel bit steep dive gear, the higher wind pressure chisel bit steep dive gear. Steep dive gear chisel bit and DTH impact with the use, is drilling flat, speed, cut the characteristics of the deep hole drilling. So in recent years come to a more extensive application.
2. Thread connection column chisel bit tooth
Threaded connection column is mainly and hydraulic drill machine gear (or pneumatic drill machine) and hydraulic drill rod (pneumatic drill rod) supporting the use of a drill, and through the different forms of thread and drill rod cooperate, cut holes for homework, diameter of the drill bit ( diameter32-203 mm), mainly used in underground mine mining, the mining of open-pit mine, the steel blast furnace openings, etc. Speed, the grinding convenient.
3. Taper connecting column chisel bit tooth
Taper connection column tooth is mainly and chisel bit pneumatic drill machine and taper stem supporting the use of a drill, and through the taper and drill rod connection, and the cut holes for homework, mainly used in mines, the secondary crushing, anchor support, the mine roadway excavation, etc.
I company produces the column teeth drill according to ISO international standard design. The symmetric structure design. Have good row powder effect and broken ability, determining the speed.
Suitable for: and tin shui, shenyang and pneumatic drill machine, hydraulic drill supporting the use of the car, etc, and is suitable for the coal, iron ore, coal, gold, copper, such as lead-zinc mine mining, railway, tunnel, railway, highway engineering construction
