What is the difference between drill pipe and drill collar?

Drill pipe is lighter and mainly transmits power; drill collar is heavier and provides weight on bit.

What materials are drill pipes usually made of?

They are typically made of high-strength alloy steel to resist fatigue, wear, and high pressure.

Key features

The DTH Drill Rod is a core component connecting the DTH Hammer, widely used in mining, water well drilling, geological exploration, and construction projects.

Drill rods are made of high-grade alloy steel (e.g., 42CrMo, 35CrMn) and undergo precision heat treatment and surface hardening, delivering exceptional fatigue resistance, wear resistance, and impact

Drill rods ensure high drilling efficiency and extended service life even in harsh rock formations.
