1. The tungsten carbide matrix is paired with high-strength polycrystalline diamond compact (PDC), delivering high hardness and strong wear resistance, making it suitable for various geological conditions.

2. It incorporates chip removal structures and an internal water channel design, facilitating the discharge of cuttings and reducing the risk of clogging.

3. The reverse cutting structure ensures smooth retraction of the drill during operations.

4. The rationally arranged water flow holes cool the drill bit during drilling, extending its service life.

5. The built-in anti-backflow device prevents debris such as coal slag and rock chips from entering the screw motor, thereby protecting it from damage.
