Drill Rod
Made of high-strength alloy steel (such as 27Crmo44 and S135 grade steel), it has excellent fatigue resistance and torsion resistance after heat treatment and precision processing, and is suitable for high-load working conditions.
We usually provide customers with one-piece forged drill rod. If you need friction welded drill rod, we can also provide it.
We offer drill rods for nearly all Vermeer and DitchWitch HDD drill models, as well as all Chinese brand rigs such as XCMG and Goodeng. Please provide your drill machine model for confirmation before purchasing.
Yes, we have extensive experience in processing according to customer drawings or designing drill rods for modified HDD drilling machines.
Different drill rods have different bending radius. Please click on your drill model to enter the product details page and view the specific values in the parameter form.
We have ample inventory for standard sizes and can ship worldwide within 3-5 days of ordering. For items not in stock, the lead time is 10-20 days.
The shipping cost depends on the way you choose to get the goods. You can choose by sea or by railway. Generally, by seafreight is the best solution for big amounts. Exactly freight rates we can only give you if we know the details of amount, weight and way. Please contact us for further information.

A barrel reamer is pulled through a pilot hole to enlarge it for pipe installation. It rotates as it’s pulled back, using drilling fluid to stabilize the borehole and remove cuttings.
Multiple passes may be required for larger pipe installations, typically over 36 inches in diameter. This gradual enlargement process helps maintain borehole stability and ensures proper sizing for the final product pipe.
Drilling fluid, often a mixture of water and bentonite clay, helps lubricate the reamer, stabilize the borehole walls, and carry cuttings out of the hole. It’s crucial for maintaining the integrity of the bore during the drilling and reaming process.
Reamer selection depends on factors like soil conditions, pipe diameter, and project requirements. Contractors typically choose a reamer diameter at least 1.5 times the width of the product pipe to be installed.
Regular maintenance includes daily inspections of threads and fluid ports, weekly checks of cutter blades and bearings, and monthly evaluations of shaft integrity. Proper cleaning and lubrication after each use are also essential for optimal performance and longevity.
