The use of a larger drill bit with a smaller anchor bar can adversely affect drilling performance. To address this challenge, a anchor drill bit adapter is employed to connect larger-diameter drill bits with smaller-sized anchor bars, ensuring compatibility and efficiency during anchor bar drilling operations.
The self-drilling anchor anchor drill bit adapter is engineered to seamlessly connect smaller-threaded anchor bars with larger-threaded drill bits, ensuring optimal compatibility and efficient operation.

The self-drilling anchor system is an advanced anchoring solution on the market. It provides stability in soil or rock formations and is a key anchoring system in rock reinforcement projects, ensuring safety and structural rigidity.
Our self-drilling anchor is equipped with different parts. At the drilling end is the anchor bit, which creates the borehole while facilitating grouting. The anchor bolt, serves as the primary support structure. The anchor coupler extends the bolt's length when necessary, while the anchor plate distributes surface loads to ensure stability. Finally, the anchor nut locks the system securely in place, completing the setup for optimal performance.
