DTH Hammer: HQL60A-H-DS
Description
HQL60A-H-DS
Black Diamond Down‑the‑Hole (DTH) Hammers are purpose‑built for blasthole drilling applications, delivering reliable performance, high penetration rates, and long service life in demanding surface mining and quarrying operations.
Manufactured from premium alloy steel and precision heat‑treated for strength and durability, Black Diamond hammers provide efficient energy transfer from the drill rig to the bit. This results in consistent hole depth, improved straightness, and dependable drilling performance in hard and abrasive rock formations commonly encountered in blasthole drilling.
Robust internal components are designed to minimise wear, reduce air loss, and maximise uptime, helping operators maintain productivity and control operating costs across long drilling campaigns.
