DTH (down-the-hole) drilling utilizes a hammer positioned at the bottom of the drill string, powered by compressed air transmitted through drilling rods. This system drives the piston to generate impact power that effectively drills and crushes rock formations. DTH drilling is widely applied in mining, quarrying, water well drilling, and foundation piling operations.
Experience revolutionary drilling efficiency with the QL Series, delivering exceptional power in Down-the-Hole applications. Designed for general-purpose use in exploration, construction, and mining, the QL Series represents adaptability, simplicity, and superior performance while minimizing operating costs.
The QL Series prioritizes simplicity and serviceability, featuring modular components and snap-in cylinders that facilitate easy maintenance and swift replacements, significantly reducing downtime and operational expenses.
Adapting seamlessly to diverse drilling requirements, the QL Series includes a reversible casing and multiple customization options for operational flexibility across various drilling applications. The hybrid valved design maximizes air compressor productivity and optimizes air usage for enhanced overall drilling efficiency.
