Cross-drilling is a service performed in the manufacturing industry that involves drilling holes through a material at an angle perpendicular to the surface. This process is commonly used in the production of engine components, such as pistons and connecting rods, as well as in the manufacturing of aerospace and defense components. Cross-drilling is a precision process that requires specialized equipment and skilled technicians to ensure accuracy and consistency.
The cross-drilling process involves the use of a drill bit that is angled to create a hole that intersects with another hole at a perpendicular angle. This creates a channel through the material that allows for the passage of fluids or gases. The process is often used in the production of engine components to improve cooling and lubrication, which can increase performance and extend the life of the engine.

Rock Drilling Bits Classification
Today, modern rock drilling and blasting technologies and geotechnical excavation operations have become the main method of obtaining resources from rock and opening up underground space for survival and development. Therefore, long-term cooperation of experts in rock drilling, blasting, rock crushing, mining, materials, metallurgy, steel and machinery is needed. The development of long-life rock drill bits has become a major engineering technology problem that must be solved in the global mining industry in the new century in order to handle rocks efficiently and at low cost.
The mining industry is one of the basic industries of the national economy. In order to improve the economy and habitat, we need to extract more resources, expand a wider living space, build easier roads, and construct more energy and defense bases. 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 get more about types of drill bits used in mining.
1. Rock Drill Bit Types
(1). Button Drill Bit
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 mine, iron ore, gold mine, copper mine and lead-zinc mine, 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 drill. It has strong drilling ability and is suitable for high hardness and complex rocks. It is widely used in highway, railway, water conservancy construction tunnels, coal mine, iron mine, gold mine and other mining excavation.
(5). Horseshoe Drill Bit
Horseshoe rock drill bit is suitable for all kinds of steel plants, blast furnace and ladle. Its main characteristics are fast opening speed and easy to control the depth and angle of channel and iron hole. The maintenance of iron hole mud bag is simple and saves manpower.
2. 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;

Rock Drill Bit Sizes
Different top hammer rock drill bit sizes are used for various drilling applications, depending on the type of rock formation being drilled and the drilling method used. Here are some examples of how different top hammer rock drill bit sizes can be used in different applications.
Small diameter top hammer button bits (less than 2 inches): These are commonly used for drilling shallow blast holes, anchor holes, and exploration drilling in soft to medium-hard rock formations.
Medium-diameter top hammer button bits (2 to 4 inches): These are used for drilling medium blast holes in medium-hard to hard rock formations. They are also used for tunneling and drifting applications.
Large-diameter top hammer button bits (greater than 4 inches): These are used for drilling large blast holes in hard rock formations. They are also used in construction and mining applications, such as drilling shafts and tunnels.
Selecting the right top hammer rock drill bit size for the specific application is critical to ensure efficient drilling and maximum productivity. The rock drill bit sizes should be selected based on the hardness, density, depth of rock formation, and the drilling method being used. Additionally, other factors such as the type of rock drills and the power of the drilling machine may also influence the choice of button bit size.

Rock Drill Bit Maintenance
Maintaining rock drill bits is crucial to ensure their longevity and performance. Here are some tips on how to maintain rock drill bits:
Clean the Bit Regularly: After each use, clean the bit thoroughly with a wire brush to remove any debris, dirt or rock particles that may be stuck in it. Failure to clean the bit regularly may lead to a buildup of debris that can cause damage to the bit and affect its drilling performance.
Inspect the Bit: Inspect the bit regularly to check for any signs of damage such as cracks, worn-out buttons or cones, or excessive wear. If any of these signs are present, it may be time to replace the bit.
Keep the Bit Lubricated: Lubrication is essential for the proper functioning of the bit. Make sure to use the recommended lubricants and ensure that they are applied correctly.
Store the Bit Properly: When not in use, store the bit in a dry and cool place, away from direct sunlight and moisture. This helps to prevent rust and corrosion that can affect the bit's performance.
Sharpen the Bit: A dull bit can reduce drilling efficiency and increase wear and tear. Regularly sharpen the bit using a sharpening stone or file to maintain its sharpness.
Use the Bit Correctly: Proper use of the bit is also important for its longevity. Use the correct drilling technique and avoid applying too much pressure, which can cause the bit to break.
By following these tips, you can maintain your rock drill bit and ensure that it performs at its best.
