Tools used in rock and soil engineering are called rock drill tools, widely utilized in construction projects such as mining, hydropower, tunnels, culverts, subways, and municipal infrastructure. The raw material used for rock drill tools is called rock drill steel.
Rock drill tools encompass six major categories (jackhammer-type, rotary-type, scraping-type, down-the-hole-type, tooth wheel-type, shield-type, etc.), with over 2000 different specifications. Following the theories of Marx and Darwin, regardless of whether humans evolved from hominids or apes, throughout the course of human development, from tool usage to tool manufacturing, from stone tools, bronze tools, iron tools to the current information age, humans have always interacted with rocks and soil (rapidly perforating the earth). This interaction will continue into the future, thus rock drill tools will also continue to be utilized.
Rock drill tools are divided into long drill tools (drill rods) and short drill tools (drill heads, drill tails, connecting sleeves). In the process of drilling rock and soil, they endure longitudinal stress (tension, compression), bending stress, torsional stress, as well as corrosion from mine water. They face complex forces, harsh conditions, and have a short lifespan.
To produce high-quality rock drill tools, it requires high-quality raw materials (steel, hard alloy for rock drilling, welding materials, etc.), advanced technology and equipment, and highly skilled employees. In addition, construction teams need to correctly select, use, and store drill tools, and drill tool companies need to provide excellent after-sales service. From start to finish, every link is crucial.
Rock drill tools are tools processed through hot working, cold working, heat treatment, anti-corrosion treatment, strengthening, etc., using raw materials (steel, hard alloy for rock drilling, welding materials, etc.). Users can use them directly, but it should be noted that drill tools are consumable tools and cannot last forever; the key is how to prolong their lifespan.
