Drill rod is a tool used to connect rock drill bit and rock drill, and is an indispensable part of rock drilling tools. There are many types of drill rods, such as tapered drill rods, and threaded extension rods. In addition, there are some special-purpose drill rods. These drill rods include suction drill rods, electric drill rods, coal drill rods, etc.

1. Suction drill rod

In the mining production, tunnel construction, and water conservancy construction of drilling and blasting projects, construction party usually uses rock drills and wet rock drilling. This wet drilling removes rock dust through water. However, in some places, due to the project being located in the high mountains, it is difficult to carry out wet rock drilling facing cold and lack of water, so they are forced to use dry rock drilling for digging. Dust concentration produced by dry rock drilling without dust prevention measures is very harmful to human health, while the dry rock drilling dust suction rod and its dust replenishment system are equivalent to the level of wet drilling in the same condition when used for rock drilling. It effectively solves the dustproof problem of dry rock drilling.

2. Electric drill rod

Electric rock drills are special drill rods used for electric rock drill drilling. It is mainly used to transmit the impact and twisting energy of an electric rock drill to achieve the purpose of drilling rock holes. Electric rock drill has characteristics of light weight, low vibration, low noise, no dust, no smoke, no pollution, and easy operation. It is ideal to improve the labor intensity and operating environment. Electric rock drill rods came into being with the rapid development of electric rock drills.

3. Coal drill rod

Coal drill rod is a drill rod made of solid and hollow steel with a diamond cross-section or impeller cross-section. It is used for drilling in rocks with low hardness and soft rocks, mainly for coal mining operations. Coal drill rods are classified by drilling methods, including solid coal drill rods for dry drilling and hollow coal drill rods for wet rock drilling.
