Import Dth Hammer Bit Dhd340 — Buy in Bulk from Supplier in China

The DTH Hammer Bit DHD340 supplied by Great Wall Diamond Drill Co., Ltd. is a precision‑engineered tool for direct‑through‑hammer drilling. It is offered in a series of diameters ranging from 60 mm to 180 mm, covering the majority of borehole sizes used in the industry. Each bit incorporates air‑hole gauges that range between 2 mm and 6 mm, providing effective dust extraction and cooling. Constructed from wear‑resistant alloy steel, the bit is capable of drilling both soft and hard rock formations with consistent performance.

Typical DTH bits of this class employ high‑strength alloy steel that meets the ASTM A681 standard for impact tools. The size lineup commonly follows 60 mm, 80 mm, 100 mm, 130 mm and 180 mm increments, which aligns with standard rig specifications. Air‑hole designs adhere to the ISO 9001‑based manufacturing process, a norm for export‑grade drilling equipment. Performance data usually shows a penetration rate of up to 1.5 m per minute in medium‑hard rock, a benchmark that buyers compare across suppliers.

These bits are widely used by mining contractors, civil‑construction firms and geological survey teams that require reliable deep drilling. The supplier mentions flexible minimum order quantities and offers both FOB and CIF shipping options to accommodate varied logistics needs. Although the listing states that the product complies with international standards, importers should request the specific certification documents and confirm lead times before finalising the purchase.

Great Wall Diamond Drill Co., Ltd. is based at Xin Yao North Road, Tian Xin District, Chang Sha 410000, Hunan, China. The company is categorized as an imported supplier with a harbor trust tier, indicating that its business credentials have been validated by third‑party checks. Platform data shows a 0 % response rate and no recorded average response time, so direct communication should be established to confirm availability.
