Product Description
H22 Alloy Drill Bit for Coal Mining with Wear and Impact Resistance
Coal mining alloy drill bits are carbide-based drilling tools specifically engineered for underground drilling operations in coal mines. Featuring a hard alloy core as the cutting component, these drill bits offer exceptional wear resistance and impact resistance, making them ideal for the complex geological conditions encountered in coal mining environments.
Key Features & Construction
- Carbide Cutting Inserts: The core working end features welded cemented carbide inserts that directly crush coal and rock formations during drilling operations
- Alloy Steel Body: Constructed from high-strength alloy steel to connect with drill rods and transmit drilling rig torque and thrust
- Efficient Chip Removal: Specially designed chip removal grooves effectively expel coal and rock debris, preventing drill bit clogging
- H22 Compatibility: Connection interface designed for H22 drill rods, ensuring quick connections with high strength to withstand high-frequency impacts and torsion
Material Specifications
Alloy Material: YG8C / YG9C / YG10C
Hardness: Over HRA85
Performance: Superior wear resistance compared to ordinary carbon steel with excellent impact toughness to handle hard inclusions in coal seams
Body Material: High-strength alloy structural steel (42CrMo) with heat treatment to withstand high torque, frequent vibrations, and provide exceptional fatigue resistance
Applications
- Geological exploration in underground coal mines
- Construction of gas drainage and pressure relief boreholes
- Drilling for underground water exploration, drainage, and grouting reinforcement
- Drilling of pilot holes for roadway anchor bolt/cable support
