Product Q&A

Q:Why should we choose a Large Diameter DTH Hammer over traditional top-hammer drilling for deep holes?

In DTH drilling, the piston strikes the drill bit directly, meaning almost no energy is lost during transmission. This direct impact mechanism gives DTH drilling a nearly constant penetration rate regardless of hole length, making it vastly superior and more energy-efficient for deep-hole applications.

Q:Do you provide technical support to help us select the right large diameter hammer for our specific project?

Yes, we provide comprehensive technical consultation. Please share your project details, including hole diameter, target depth, and geological conditions. Our engineering team will recommend the optimal piston weight, stroke, and shank configuration to maximize your drilling efficiency.

Q:What is the lead time for ordering a customized 300mm Large Diameter DTH Hammer?

For standard large diameter models, we maintain ready-to-ship inventory for immediate dispatch. For fully customized sizes or specialized shank configurations, the typical production lead time is 15-20 days. Contact us for an exact delivery schedule based on your current order volume.
