The Hunan Tianying Drilling Machine Manufacturing Co.,Ltd. offers a rock drill bit built around a steel body fitted with tungsten carbide inserts. The inserts are conical and positioned on both the gauge and inner rows to maintain durability during prolonged use. This design targets medium‑hard to hard abrasive formations such as sandstone, limestone, dolomite and soft granite. The drill operates effectively within a pressure range of 29 000‑38 000 psi and incorporates a roller‑ball‑roller thrust bottom sealed bearing.
Tungsten carbide provides a high compressive strength that exceeds typical steel bits, reducing wear in harsh geological conditions. In the rock‑drilling industry, similar tools often use a 3‑inch chuck and are sized for a 102 mm drill diameter, which aligns with this bit’s dimensions. Standard operating speeds for such bits lie between 200 and 300 rpm, allowing consistent penetration without excessive vibration. The bit’s overall weight is around 45 kg, a common figure for medium‑size rock drill bits, facilitating handling on most drilling rigs.
Primary users include mining contractors, quarry operators and companies drilling blast holes for construction projects. The supplier states the product is ready for global export and can be supplied in bulk quantities, though exact minimum order quantities and lead times should be confirmed directly. Buyers are advised to discuss Incoterms, payment conditions and any required certification documents before placing an order.

Before placing an order, importers should verify the supplier’s business licence and factory address in Zhuzhou, Hunan Province. Request a product data sheet that confirms the material composition, insert geometry and operating pressure range stated in the listing. Ask for any third‑party test reports or certification documents that demonstrate compliance with relevant drilling standards. Confirm the minimum order quantity, lead‑time and payment terms in writing.
Discuss the preferred loading port with the supplier; common Chinese export ports for drilling equipment include Shanghai, Guangzhou and Tianjin. Clarify the Incoterms, such as FOB Zhuzhou or CIF destination, to align cost responsibilities. Lead‑time estimates should be obtained before contract signing, as they can vary with order size and production scheduling. Agree on payment milestones, for example a letter of credit at sight or a 30 % deposit.
Arrange a pre‑shipment inspection by an independent inspection agency to verify the conical tungsten carbide inserts and bearing assembly. Request a final test report that records the operating pressure performance and dimensional tolerances of the bit. Ensure the supplier provides a certificate of origin and a packing list that matches the agreed specifications. Maintaining these documentation checks helps avoid disputes on arrival.
