Application of DTH Drill Rods:
The drill rod connects the DTH hammer or auger to the rig, extending reach as the hole gets deeper while transmitting torque and carrying air, water, or slurry down to the bit through the length of the string.
Features of DTH Drill Rods
– Thick-walled tube in high-strength alloy steel (SCM, S45C).
– Threaded box-and-pin connections built to API standards.
– Hexagonal-profile joints for reliable torque transmission.
– Available in hexagonal (torque-focused), round (deep-hole), and DTH-specific (internal air passage) types.
– Thread options: API, R38, T45, T51; joint types: T4, 120H, 240H.
Note: Confirm thread standard and joint type to match your hammer and rig before ordering.
