Import Dth Hammer Dhd350,Cop54,Sd5,Ql50 — Buy in Bulk from Supplier in China

The DTH Hammer DHD350, identified by the codes COP54, SD5 and QL50, is a high‑air‑pressure rock‑drilling hammer intended for ore mining, quarrying, well drilling and other heavy‑construction projects. It is engineered to work with standard DTH drilling pipes and bits, and it can be interchanged with equipment from Atlas Copco and Ingersoll‑Rand, providing flexibility for users with mixed fleets. The hammer’s internal structure follows the latest rock‑drilling theory, delivering fast drilling speeds while consuming less air and oil than older designs.

According to the supplier, the DHD350 is rated for drilling holes between 138 mm and 165 mm in diameter. The COP‑54 air‑hole gauge and the SD‑5 sealing design give a typical air‑hole size of about 5 mm, while the QL‑50 rating reflects a standard impact energy class for this size range. The body is forged from high‑strength alloy steel and the impact head uses a tungsten‑carbide insert, a combination that is typical for durable DTH hammers in hard‑rock environments. Expected operating air pressure is around 0.7 MPa, which aligns with industry practice for this class of equipment.

Primary users include mining contractors, quarry operators and drilling service companies that require reliable, low‑maintenance hammers for deep‑hole drilling. The supplier mentions flexible MOQ options and offers packaging in inner cartons placed inside wooden outer cases. Shipping can be arranged on FOB or CIF terms, and export‑quality certifications are attached to each batch. Prospective buyers should verify the exact MOQ, certification scope and payment conditions directly with the supplier before committing.
