Multi Hexagon Rock Drill Bars

Product Overview Multi Hexagon Rock Drill Bars are high-quality alloy steel drilling bars manufactured for rock drilling systems. With hexagonal cross-section design, they transfer impact force and rotary torque efficiently during drilling work. They can be connected with Coupling Sleeve to build a complete drill string for rock boring. Key Advantages These drill bars undergo strict heat treatment to achieve excellent toughness and wear resistance. The hexagonal structure improves torque transmission and reduces energy loss. They can coordinate with Fully carburized taper drill rods to keep the whole drilling assembly stable, lowering breakage risk and extending service life in hard rock drilling. Detailed Features Precision thread processing at both ends ensures reliable connection. Black surface treatment provides protection against abrasion and rust. Belonging to Tapered Drilling Tools, they can be matched with Round Extension Drill Rods. When combined with Threaded Coupling Sleeve,…
