The Coal Mining Equipment Spiral Drill Rod offered by Linqing City Ruilong Drill Co., Ltd. is designed for small‑hole drilling in coal mining operations. Standard rod diameters range from 19 mm to 22 mm, while the borehole sizes they can produce are typically between 29 mm and 41 mm. The rods feature a hexagonal cross‑section with either chisel or cross tips to facilitate chip evacuation. Lengths are supplied from 600 mm up to 9 600 mm, allowing adaptation to various drilling depths.
The product is manufactured from high‑strength hollow drill steel, a material commonly used for its balance of rigidity and weight, and the cutting tips are fitted with tungsten carbide for enhanced wear resistance. Typical tensile strength for the steel exceeds 1 200 MPa, and surface hardness is usually above 60 HRC, meeting the demands of abrasive rock. These specifications align with industry standards for integral drill rods used with pneumatic or electric hand‑held drills.
The rods are employed by mine contractors and drilling service providers who require reliable penetration in coal seams and associated strata. Trade can be arranged on FOB or CIF terms, with payment options such as L/C or T/T, and the supplier mentions flexible order quantities to suit project scales. Each rod is bundled and wrapped in protective film for sea freight, and the supplier can provide a packing list and weight calculations on request.

Importers should first confirm the legal status of Linqing City Ruilong Drill Co., Ltd. by requesting a copy of its business licence and tax registration in China. Verify the exact rod dimensions, material grade and tip type against the project specifications. Ask for recent production photographs or a virtual factory walkthrough to assess manufacturing capability. Because response metrics are not available, test the communication speed before committing to a contract.
When arranging shipment, clarify whether the transaction will be on FOB or CIF terms and identify the destination port for sea freight. The supplier can provide an estimated manufacturing lead time, which typically depends on the selected length and quantity; confirm this timeline to align with project schedules. Payment is usually structured as L/C or T/T, and a detailed pro‑forma invoice should be obtained prior to any advance payment.
Before loading, schedule an independent third‑party inspection focusing on rod straightness, dimensional accuracy and tip integrity. Request the supplier’s material test reports for tensile strength and hardness to ensure compliance with the stated typical values. Upon arrival, inspect the protective film wrapping for damage and conduct a simple torque test on a sample rod to verify suitability for the intended drilling equipment. Document any discrepancies immediately to facilitate corrective action.
