The DTH hammer models offered by Jessin Rock Drill Co., Ltd. include DHD3.5, DHD340, DHD350, DHD360, DHD380, DHD112, and others, each designed for specific borehole diameters and operating pressures. These hammers are built for high-pressure applications ranging from 1.0 to 2.4 MPa, with shank diameters from 85 mm up to 610 mm, matching standard drill rig interfaces such as BR3, DHD3.5, COP34, M40, and SD12.
The hammer bodies are constructed from hardened alloy steel with precision-machined internal components to withstand high-impact loads. The button bit sizes range from 90 mm to 610 mm, with corresponding shank configurations tailored to each model. Standard operating parameters include impact rates of 20 to 30 Hz and air consumption rates up to 10.5 m³/min at peak pressure, depending on size. No specific material grade or hardness values are provided, but the design follows typical Chinese industrial standards for mining-grade DTH tools.
These hammers are primarily used in large-scale mining, tunneling, and quarry operations where deep, high-diameter boreholes are required. Buyers include heavy equipment contractors in Southeast Asia, Africa, and South America who require cost-effective, high-volume drilling tools. Packaging is typically in steel crates with foam padding, and trade terms are usually FOB from a Chinese port. Lead time is typically 3 to 5 weeks. No certifications are listed; buyers must request material traceability and pressure test records.

Sourcing DTH hammer from Jessin Rock Drill Co., Ltd. - China Import Guide
Before ordering, confirm the exact model number (e.g., DHD360, DHD112) and its corresponding shank type, bit size, and connection standard. Request material traceability documents and pressure test reports, as no certifications are listed. Ensure the supplier provides a dimensional drawing matching your rig’s specifications to avoid compatibility issues.
Lead time is typically 3 to 5 weeks from order confirmation, with FOB Shanghai or Ningbo as common terms. Payment is often 30% advance and 70% against copy of BL. Confirm if the supplier includes export documentation, and verify whether Incoterms include insurance. Air freight may be used for urgent orders but significantly increases cost.
Conduct a pre-shipment inspection focusing on thread integrity, surface finish, and internal cleanliness. Request a pressure test log showing performance at 2.4 MPa. Ensure packaging includes moisture barriers and that each hammer is individually labeled with model, serial number, and test date. Retain sample pieces for quality comparison on future orders.
