High-quality geological drill rods designed for rock drilling applications, manufactured using advanced friction welding technology for superior performance and durability.

The drill rod body is constructed from special alloy steel (R780, DZ50), while the drill bit is made of premium alloy structural steel (42CrMo). The materials undergo true air conditioning treatment to significantly enhance anti-fatigue strength and anti-shear strength.

Produced using advanced friction welding technology, these drill rods feature high bending strength and robust welding joints. This ensures excellent straightness for deep hole drilling applications, along with exceptional fatigue resistance and extended service life.

• Manufactured to exacting specifications using advanced machining technology for superior quality
• Constructed from seamless steel tube via cold drawn process using XJY850/30CrMnSiA material meeting global standards
• Heat-treated materials ensure exceptional strength, wear resistance, and toughness for demanding applications
• Produced under stringent industry standards and field-tested in various conditions
• Designed for compatibility with other rods manufactured to DCDMA standards
