High Strength Alloy Steel Connecting Drill Rod for Hydraulic Rock Drilling Rigs

The rig connecting drill rod is a specialized connector designed for hydraulic rock drilling rigs. It serves as a critical component for connecting and extending drill bits between the drill head and drill shank, between the drill shank and drill rod, or between multiple drill rods. This essential part transmits impact and torque in tunnel construction, mining operations, slope support, and foundation pit anchoring projects.

Key Features

Compatible with Rock Drilling Rigs - Specifically engineered for hydraulic rock drilling rigs, ensuring seamless integration with feed, rotation, and impact systems for stable connections and high concentricity.
Reliable Connection & High Transmission Efficiency - Features standard threaded interfaces (including R25/R28/T38/T45) that maintain high precision while minimizing torque and impact energy transmission loss.
High Strength & Fatigue Resistance - Manufactured from premium alloy steel using integral forging and precision heat treatment processes, providing exceptional resistance to bending, impact, and fatigue for long-term heavy-duty operation.
Quick Assembly & Disassembly - Enables rapid connection and extension of drill rods to meet varying drilling depth requirements, with compatibility across multiple rig drilling machines and matching drill bits.
Versatile Applications - Suitable for tunnel excavation, mining operations, slope anchoring, water conservancy projects, foundation pit support, and various trolley drilling operations.
