DTH drilling Bit DHD350,COP54,SD5,QL50
The DTH drilling Bit DHD350,COP54,SD5,QL50 is produced by Great Wall Diamond Drill Co., Ltd. and falls within the CH55 series, offering a nominal diameter range of 140‑180 mm. The bit is forged from alloy steel and incorporates carbide processing, with a spherical‑ballistic button and a flat‑face, drop‑center, convex, double‑gauge, or concave face selectable per order. Production capacity is listed as 5 000 sets per month and the model carries the ISO 9001:2008 certification as stated in the catalogue.
Typical DTH bits of this size are designed for ore‑mining, quarrying and well‑drilling applications, delivering high penetration rates while maintaining hole cleanliness. The alloy‑steel body usually achieves a hardness of HRC 58‑62 and a weight of roughly 12‑15 kg for a 150 mm diameter bit, which is standard for the category. The forging process and heat‑treatment enhance durability and provide an energy‑saving advantage compared with lower‑grade alternatives.
Importers such as mining contractors, water‑well developers and large‑scale construction firms often select this bit for its interchangeable design with global brands. The supplier advertises no minimum order quantity, but buyers should confirm packaging (standard export cartons or custom wooden cases) and negotiate Incoterms and lead‑time directly. Payment methods include T/T, Western Union or PayPal, and the supplier recommends DHL for trial orders and sea freight for bulk shipments.

Sourcing DTH drilling Bit DHD350,COP54,SD5,QL50 from Great Wall Diamond Drill Co., Ltd. - China Import Guide
Before placing an order, verify the exact diameter, material grade and button/face shape options required for your drilling project. Request a mill test report or hardness certification to ensure the alloy‑steel body meets the typical HRC 58‑62 range, and confirm the packaging format that will protect the bits during transport.
Logistics for this product are usually arranged on FOB terms from the port of Chang Sha, but the listing does not specify the exact port, so ask the supplier to confirm departure details. Lead‑time is not disclosed; obtain a production schedule and agree on Incoterms and payment milestones, such as a T/T advance and balance on sight L/C after shipment.
Quality assurance is essential for high‑pressure drilling bits. Ask the supplier to arrange a third‑party pre‑shipment inspection and provide documentation such as the ISO 9001:2008 certificate and any applicable mill test reports. Clarify the supplier’s warranty or replacement policy in case the bits do not conform to the agreed specifications.
