Product Description
QL50-130mm DTH Hammer Drill Button Bit for Water Well Drilling
The QL50-130mm DTH (Down-the-Hole) drill bit is an industrial-grade drill designed specifically for use with the 5-inch QL50 impactor. With a typical diameter of 130mm (5 1/8"), this robust tool is widely used in demanding hard rock drilling operations including mining, quarrying, water well drilling, and construction engineering.
Technical Specifications and Features
- Applicable Diameter: QL50 series drill bits typically range from 130mm to 165mm
- Operating Pressure: Recommended for high-pressure environments of 10-25 bar (1.0-2.5 MPa); some models can withstand higher impact energy
- Materials and Construction: High-quality alloy steel body with high-performance tungsten carbide ball teeth, forged and heat-treated for enhanced fatigue and wear resistance
- Efficiency Performance: Under specific geological conditions, achieves average drilling speeds up to 30 cm/min with service life exceeding 500 meters
