The Characteristics And Applications Of Button Bits

The button bit passivation has a long service life, and its service life is about 5-6 times the grinding life of the drill bit with the same diameter, which is beneficial to saving auxiliary working hours, reducing workers' physical labor and speeding up the project. Therefore, tapered button bits and threaded button bits of different diameters are widely used in various types of hard and brittle rocks to cooperate with drilling rigs for rock drilling. Swedish engineering and technical personnel believe that the combination of ball-tooth drill bits and hydraulic rock drilling rigs is the best match for modern rock drilling technology. In the past 20 years, Button bits have developed rapidly at home and abroad. It has been realized with the goal of rapid drilling of hydraulic rock drills to save auxiliary drilling hours and increase industrial drilling speed.

Compared with traditional chip drill bits, Button bits have the characteristics of longer grinding cycle and faster drilling speed. They are mainly divided into the following categories:

Tapered button bit

The tapered button bit is mainly a drill bit used in conjunction with the pneumatic rock drill and the taper rod. It is connected with the drill rod through the taper to perform drilling operations. It is mainly used in secondary crushing of mines, anchor support, and tunnels. excavation and other fields. The column tooth drill bits produced by our company are designed according to ISO international standards. Adopt symmetrical structure design. It has good powder discharge effect, strong crushing ability and fast rock drilling speed.

Threaded button bit

The threaded connection column tooth is mainly a drill bit used in conjunction with a hydraulic rock drill (or pneumatic rock drill) and a hydraulic drill rod (pneumatic drill rod). It uses different forms of threads to cooperate with the drill rod to perform drilling operations. The diameter of the drill bit is: ￠32-￠203mm, mainly used in underground mining, open-pit mining, blast furnace openings in steel plants, etc. It is fast and easy to grind.

DTH button bit

The DTH button bit is a drill bit used in conjunction with the DTH hammer.It cooperates with the impactor to perform drilling operations.It is widely used in open-pit mining, quarries, hydropower projects, and drilling of water wells.Excavation side pillar support,etc. They are divided into: low-pressure DTH button bits, medium and high air pressure DTH drill bits. The down-the-hole column drill bits are used in conjunction with down-the-hole impactors and have drilling flatness. It has the characteristics of straightness, fast speed and deep hole drilling. Therefore, it has been widely used in recent years.
