Product introduction:
Drilling tools are matched with drilling rigs in coal mines for water exploration, gas exploration, and pressure relief holes.
The drill bits are divided into two categories: high-efficiency anti-collapse hole drill bits and geological drill bits; high-efficiency auger rods and geological drill rods are selected according to different needs and working conditions.
Technical features:
1. Drilling bit series:
High wear resistance
Made of wear-resistant alloy steel, it has high impact toughness and high fatigue limit, high strength and strong wear resistance;
High welding strength
Adopt low temperature vacuum diffusion welding process, use imported flux and solder to ensure welding strength and prevent chip drop.
Long service life
The use of high-quality grinding discs has the characteristics of high precision, long working life, fast drilling speed, less drilling times and low production costs.
2. Drilling drill rod series:
High strength and low loss rate
Rod body - adopts BaoGang high-quality geological rod R780, with high tensile strength and yield strength;
Joints - high-quality alloy structural steel is used for vacuum air conditioning to improve fatigue strength and shear strength;
High welding strength
The advanced phase friction welding machine is used for production and processing. The drill rod has high bending strength and reliable welding, which meets the requirements of deep hole eccentricity, improves fatigue resistance and prolongs service life.
Reliable connection
The auger rod adopts hexagonal plug-in connection and pin-shaft fixation, which has higher connection strength
