The Dth Drill Bit offered by Zhuzhou Changhong Mining Machinery Co., Ltd. is a rotary‑percussion tool designed for rock drilling in mining and tunnelling projects. The supplier states that it manufactures DTH drill bits for high, medium and low air‑pressure hammers, and that the bits are compatible with both concentric and eccentric drilling systems. The product line also includes threaded drill bits, shank adapters and coupling sleeves as part of a broader rock‑drilling accessory range.
Typical DTH drill bits use a tungsten carbide tip bonded to a steel body, delivering a hard‑facing that resists wear in abrasive formations. Industry practice favours diameters between 63 mm and 152 mm and a maximum rotational speed of around 200 rpm, which matches the pressure categories mentioned by the supplier. The bits are usually supplied in standard lengths of 1.5 m to 3 m, with weight per metre ranging from 10 kg to 15 kg depending on diameter.
These bits are commonly purchased by underground mining contractors, tunnel builders and specialised drilling service firms that require reliable rock‑cutting performance. Importers should confirm the exact air‑pressure rating, shank size and any required hard‑banding before placing an order. Trade terms, packaging details and minimum order quantities are not disclosed in the listing and should be negotiated directly with the supplier.

Before placing an order, verify the supplier’s business registration, request a copy of any relevant quality certificates and confirm the exact air‑pressure rating required for your project. Ask for a sample or detailed drawings to ensure the bit dimensions match your drilling equipment. Clarify the packaging method and whether the bits are supplied with protective caps to avoid damage during transit.
Logistics for Chinese manufacturers typically involve shipment from ports such as Guangzhou or Shanghai. Confirm the preferred Incoterm (for example FOB, CIF or DDP) and ask about the estimated lead time once the order is confirmed. Discuss payment terms, such as a 30 % deposit with the balance payable against shipping documents, to align with your company’s procurement policy.
Quality control is essential for rock‑drilling tools. Request an inspection report covering hardness testing of the carbide tip, dimensional checks, and visual examination for cracks. Arrange for an independent third‑party inspection if required, and ensure the supplier can provide a test certificate that records the results of these checks.
