Product detail
Central to the DHD 55A, vital in the high-air pressure down-the-hole hammers, lies a sturdy 5.5-inch high-pressure hammer capable of delivering outstanding performance, even in the most extreme settings. Made from high-quality carbon steel, this hammer boasts unmatched longevity and dependability, adept at surviving persistent operations under challenging conditions like rocky and harsh terrain. This attribute renders it perfect for impactful drilling in mining industries, and also ideal for energy exploration and extensive construction endeavors demanding precise deep-hole drilling.


A prominent characteristic of the DHD 55A is its ability to withstand high pressure. The drill, boasting an air pressure spectrum from 1.2 to 2.0 MPa, is superior in ensuring maximum penetration and drill efficiency across a variety of hole diametrically between 136 mm and 152 mm. Such robust performance under high pressure enhances the drill's ability to manage complex geological structures, cutting down drilling duration and boosting general productivity. The DHD series is enhanced by the sophisticated DTH hammer technology, aimed at providing steady and potent force, thus amplifying the rapidity and accuracy of drilling activities.
Application
Engineered to be versatile, the DHD series for drilling holes is apt for various industry applications. This method proves particularly efficient for drilling in energy exploration, in mining projects, and on extensive construction projects needing deep and accurate drilling for laying foundations or blasting rocks. The DHD series high air pressure down-the-hole hammers, known for their versatility in rock drilling, cater to a wide array of industry requirements, offering a device that is both adaptable and efficient.


After-sales
Besides its advanced engineering, the DHD series high air pressure hammers, which require drilling down the hole, are complemented by extensive after-sales support. Consumers are provided with a warranty for three months, an in-depth equipment testing report, and video inspections to verify the product's performance prior to delivery. Additionally, there are customization features, enabling users to adjust the rig's functionality to their specific project needs.
