orientation, good cleaning effect and strong erosiveness.
3. The angle of the PDC tool is 18-25°, which makes the drill bit
have higher cutting performance.
4. Double-row PDC cutters are welded on the shoulder of the drill
bit, which can work at the same time to protect the front teeth. At
the same time, they can also complement each other. This design can
increase drilling speed and enhance the wear resistance of the
drill bit.
5. The water jet angle is optimized to improve the cleaning ability
of the drill bit. Also, it reduces the number of repeated cuts.
