Description

The QL50-130mm DTH (Down-the-Hole) drill bit is an industrial-grade drill designed specifically for use with the 5-inch QL50 impactor. Its diameter is typically 130mm (5 1/8"). It is widely used in hard rock drilling operations such as mining, quarrying, water well drilling, and construction engineering.

Technical Specifications and Features


Applicable Diameter: QL50 series drill bits typically range in diameter from 130mm to 165mm.

Operating Pressure: Recommended for operation in high-pressure environments of 10-25 bar (1.0-2.5 MPa); some models can withstand higher impact energy.

Materials and Construction: Constructed with a high-quality alloy steel body and high-performance tungsten carbide ball teeth, forged and heat-treated to improve fatigue resistance and wear resistance.

Efficiency Performance: Under specific geological conditions, high-quality drill bits can achieve an average drilling speed of up to 30 cm/min and a service life of over 500 meters.
