Down The Hole Drilling

We offer multiple hammer-to-drill connection types (pin, stop ring, Russian-style, etc.), for example, low air pressure DTH Drill bit all manufactured with exceptional cost-performance efficiency.

We provide perfectly matched drill bits for any hammer type, for example, high air pressure DTH Drill bit, with customized designs optimized for specific rock conditions—from soft to hard rock. Backed by global mining experience, we deliver the ideal solution for every drilling environment.

QL series DTH Hammer: Featuring low energy consumption, high-frequency operation, and rapid drilling speed, this equipment delivers exceptional adaptability for all working conditions. It performs outstandingly in medium-to-high pressure open-air drilling projects.

M-series DTH Hammer: Low impact energy loss, short piston stroke, high frequency, fast drilling speed. The connection between the hammer and the drill bit is of the stop ring, with six splines on the bit and impact end. It can effectively extend the working life of the product. Suitable for 10-13 bar working air pressure. Ideal for medium-hard to softer rock formations.

Mission series DTH Hammer: Featuring a cylinder-free design for simplified structure and maintenance, this hammer delivers high-impact frequency with exceptional drilling speed and reduced gas consumption. It performs reliably across all operating conditions, demonstrating superior efficiency in mine blasting-hole drilling applications.

K-series DTH Hammer: Featuring high-impact frequency and faster drilling speeds than conventional DHD series hammers, this system operates with lower air consumption. It delivers reliable performance across all working conditions and excels particularly in mine blast-hole drilling applications.

HD series DTH Hammer: Featuring low energy consumption, high-frequency operation, and rapid drilling speed, this equipment delivers exceptional adaptability for all working conditions. It performs outstandingly in medium-to-high pressure open-air drilling projects.

CIR series DTH Hammer: Low energy loss, short piston stroke, and high frequency enable fast drilling. Features a pin-type hammer-bit connection with 6-spline interface (one notched spline, no small spline at impact end). Suitable for 7-15 bar working air pressure. Ideal for medium-hard to softer rock formations.
