Rock Drilling Bits
Rock Drilling Bits Classification
Mining rock drill bits are indispensable tools in mining and infrastructure construction. Different rock drill bit types are used in mines, railroads, highway construction, ports, power station defense projects, etc., as well as in urban construction and quarrying. In this article, you will learn more about the types of drill bits used in mining.
Rock Drill Bit Types
(1). Button Drill Bit
The button drill bit is suitable for dry and wet drilling of medium hard and hard rocks. It is mainly used in all kinds of mining, transportation, water conservancy, roadway, tunnel excavation, quarrying, and rock-breaking engineering of municipal construction.
(2). Chisel Drill Bit
Chisel rock drill bit is suitable for light rock drills, drilling rock holes with a diameter of less than 50mm, and is suitable for rocks with low hardness. This bit is widely used in various mines such as coal mines, iron ore, gold mines, copper mines, and lead-zinc mines, as well as tunnel excavation in railway, highway, and water conservancy construction. Chisel Bit has mature technology, adopts high-quality steel and alloy, has high toughness and high wear resistance, high production efficiency, and low cost.
(3). Cross Drill bit
Cross rock drill bit is suitable for high-power rock drill, which can drill into complex rock strata such as rock cracks. It has strong radial wear resistance. The cross bit also adopts mature technology, high-quality steel, and alloy, has strong radial wear resistance, maintains high production efficiency, and can control the cost.
(4). Three-edge Drill Bit
Three-edge rock drill bit is suitable for high-power rock drills. It has strong drilling ability and is suitable for high hardness and complex rocks. It is widely used in highways, railways, water conservancy construction tunnels, coal mines, iron mines, gold mines, and other mining excavations.
(5). Horseshoe Drill Bit
The Horseshoe rock drill bit is suitable for all kinds of steel plants, blast furnaces, and ladles. Its main characteristics are fast opening speed and easy control of the depth and angle of the channel and iron hole. The maintenance of iron hole mud bags is simple and saves manpower.
How to Choose Rock Drill Bits
When selecting the rock drill bit, it shall be selected according to the type, performance, rock hardness, and toughness of the drill bit. Generally, the chisel rock drill bit shall be selected when there is no crack in the rock; Cross rock drill bit and three-edge bit can be widely used in various rocks, especially in hard and extremely hard rocks with high abrasive cracks; The button drill bit is suitable for all kinds of rocks except high abrasive rocks.
(1). When drilling, due to the cutter feeding too fast, grinding or drilling cold and hot may cause the phenomenon of bit fracture or sudden stop;
(2). When drilling, the air volume of the rock drill shall be reduced to reduce the damage to the drill bit caused by the high stress of cemented carbide parts.

Common Applications Of Top Hammer Rock Drilling Bits
Mining Drill Bits
In mining, top hammer drill tools are used to mine ore or explore for mineral deposits. Open pit and underground mining drill bits are essential tools in the mining industry. They play a crucial role in ensuring the safety and efficiency of open pit and underground mining operations. The types of drilling in mining come in various shapes and sizes, each designed for a specific type of rock or mining condition. For instance, some drill bits are designed with a conical shape for drilling in soft rock, while others have a flat or button shape for hard rock drilling. With the continuous advancement of technology, we can expect to see even more innovative and efficient drill bits being developed for the mining industry.
Rock Drill Bits For Quarrying
Rock drilling bits are also used in the quarrying industry to extract stone and other materials from the earth. They are used to drill holes into the rock, which are then filled with explosives to break apart the rock and extract the desired materials.
Rock Drill Bits For Tunneling and Underground Engineering
In tunneling and underground engineering, top hammer drilling tools are used to drill holes in rock for blasting or construction of underground structures.
Rock Drill Bits For Construction and foundation engineering
Top hammer drilling tools are widely used in construction and foundation engineering for drilling rocks at construction sites or bridges and other projects to place blasting agents or perform foundation work.
Rock Drill Bits In the Oil and Gas Industry
General, top hammer rock drilling tools are rarely used in the oil and gas industry. However, in certain specific geological conditions or situations requiring rock reinforcement, the use of top hammer rock drilling tools may be considered. For instance, in special areas where blasting or strengthening of rock formations is needed, top hammer rock drilling tools might be used.
Overall, top hammer drilling tools have applications wherever rock drilling and preparation are required. They provide efficient, precise, and safe rock-handling solutions that enable a variety of projects to proceed smoothly.
