Import Dth Hammer — Buy in Bulk from Supplier in China

JBT (Beijing) Rock Tools Co. Ltd. manufactures DTH hammers for rock drilling applications in mining and civil engineering, using precision-engineered components to deliver consistent impact energy at the borehole base. The tools are built to operate under compressed air systems with pressures between 0.8 and 2.2 MPa, enabling efficient penetration in medium to hard rock formations. The design minimizes energy loss through optimized air flow paths and direct impact transmission.

The hammer bodies are constructed from hardened alloy steel with tungsten carbide inserts in the bit face, consistent with industry norms for durability. Bit diameters range from 76 mm to 254 mm, with standard thread connections matching API 3-1/2 inch and 4-1/2 inch specifications. The internal valve mechanism is engineered for high-cycle reliability, with typical service life exceeding 300 hours under standard conditions. Air flushing systems are designed to remove cuttings without requiring excessive flow rates.

Primary users include open-pit mining operators, geotechnical drillers, and infrastructure contractors working in challenging geological conditions. Packaging is in wooden crates with rust inhibitors and internal foam supports. Trade terms are available on request, with FOB and CIF options mentioned. MOQ and lead time are not specified and must be confirmed directly. No certifications are listed, and buyers should request independent test reports for performance validation.
