Features
The drill tool has a simple structure,high stability, and fast drilling speed. It adopts a unique locking system structure, which makes the connection reliable and easy to disassemble.
The surface of the drill tool parts is strengthened and wear-resistant carbides are installed on the back of the eccentric wheel to improve the wear resistance of the drill tool.
Applicable formation: The surface of the stratum is mostly covered by loose material, sand and mud layers, backfill layers (without boulders), etc.
