Tungsten Carbide Button Bits
Overview
Tungsten Carbide Button Bits are primarily made from tungsten carbide and cobalt binder through powder metallurgy processing. They can be customized for different working conditions and maintain stable performance during long-term, high-intensity operations. They can be widely used in mining, petroleum, geological exploration, road maintenance, and other fields to meet the needs of various mechanical equipment.
Advantages
Extremely wear-resistant
Its hardness far exceeds that of ordinary steel and high-speed steel. It can effectively resist wear, impact, and extrusion, significantly extending its service life. It is especially suitable for harsh working conditions such as geological drilling and mining.
Excellent impact toughness
Tungsten carbide can ensure high hardness while having good toughness. It can withstand frequent impact loads without easily cracking. It is especially stable in operations that require repeated impacts, reducing failures caused by brittle fracture.
High operating efficiency
The nearly spherical structure design can generate concentrated stress through point contact, making it easier to crush rocks or cut materials. At the same time, it can maintain an effective working state for a longer time, reduce replacement frequency, and lower downtime costs.
Wide applicability
It can be designed into different sizes, shapes (such as spherical, conical, cylindrical, etc.) and alloy grades according to different working conditions, and is suitable for a variety of equipment and working environments.
Application
1. Mining and Mineral Processing
- Underground Mining: During tunnel excavation and stope development, ball teeth installed on the drill bits of roadheaders and rock drills can effectively crush medium-hard to hard rock such as shale, sandstone, and iron ore, reducing drill bit wear and increasing advance speed.
- Surface Mining: Tungsten Carbide Button Bits are used for pre-splitting drilling and ore stripping before blasting, and are compatible with equipment such as rotary drills and down-the-hole drills.
- Mineral Crushing: Ball teeth installed on the wear-resistant parts of crushers are used for fine crushing of coal, metallic ores, and non-metallic ores, extending the life of equipment wear parts.
2. Drilling Engineering
- Oil and Gas Drilling: During oil and gas well drilling, the ball teeth of rotary drill bits directly contact the hard underground rock formations, capable of withstanding the continuous wear and impact in high-pressure and high-temperature environments, ensuring drilling efficiency.
- Hydrology and Engineering: Used for drilling water wells, geothermal wells, and pilot holes in foundation surveys. Suitable for drilling rigs of various diameters, they can handle diverse geological conditions, from loose strata to hard rock.
3. Engineering, Construction, and Infrastructure Construction
- Tunnel Excavation: Ball teeth are installed on the cutter to break the surrounding rock in projects such as subway tunnels, highway tunnels, and water conservancy tunnels, reducing the frequency of tool changes.
- Pavement Engineering: Ball teeth are installed on the drill bit head of hydraulic breakers for demolition of old pavement and concrete, suitable for municipal renovation and demolition projects.
4. Metallurgy and Metalworking
- Roller Repair: Grinding tools with ball teeth are used to remove oxide layers and cracks from the roll surface to ensure roll accuracy.
- Casting Cleaning: Used to remove burrs from the surface, especially for high-strength alloy castings, to prevent excessive tool wear.
- Specialty Cutting: When cutting or forming difficult-to-machine metal materials (such as high-manganese steel and wear-resistant cast iron), ball teeth act as cutting edges, capable of withstanding high cutting forces.
5. Other Special Applications
- Stone Processing: In the mining and cutting of granite, marble, and other stone materials, it is primarily used to separate and shape rough stone blocks, improving processing precision.
- Marine Engineering: In drilling equipment used for seabed mineral exploration, ball teeth must withstand seawater corrosion and high-pressure environments to ensure stability during underwater operations.

Type
1. Spherical Butt Teeth
The contact surface is evenly distributed, distributing impact loads and reducing the risk of localized wear and cracking.
This type is suitable for drilling and tunneling in medium-hard to hard rock, as well as mining and tunneling applications with high impact loads. It is one of the most widely used types.
2. Conical Butt Teeth
The pointed tip angle is small, approximately 30°-60°; the blunt tip angle is larger, approximately 80°-120°. This creates a strong stress concentration effect and high rock breaking efficiency.
The pointed tip is primarily used for rapid hard rock crushing (such as in oil drilling and pre-blasting of hard rock); the blunt tip is primarily used for tunneling in medium-hard rock, as well as for coal mining machine picks.
3. Flat-Top Butt Teeth
The flat tip has a large contact surface and can withstand greater compressive loads, making it suitable for grinding or cutting under high pressure.
It is primarily used in metal processing (such as grinding wear-resistant parts and cutting special materials) and concrete crushing, where continuous compressive grinding is required.
4. Bullet-Shaped Button Bits
The streamlined design reduces energy consumption during operation, making it suitable for high-speed cutting or drilling.
Commonly used in high-speed drill bits, this type of bit is particularly effective in soft to medium-hard rock (such as coal seams and mudstone).
Process
① Select high-quality tungsten carbide powder, adjust the cobalt content according to the application scenario, and evenly mix the tungsten carbide powder and cobalt powder in the correct proportions.
② Use a die to press the powder particles into the shape of the ball gear blank (such as spherical, conical, flat-top, etc.).
③ Use a vacuum sintering furnace to sinter the pressed blank at high temperature to combine the powder particles into a dense alloy.
④ Use a diamond grinding wheel to grind the working surface of the ball gear to ensure dimensional tolerances and surface roughness.
⑤ Ensure product quality through multi-dimensional testing, such as dimensional inspection, performance testing, and ultrasonic testing.
