The cemented carbide nozzle is one of the important components for the diamond drill bit, tungsten carbide drill bit nozzle apply to flush, cool and lubricating the tips of the drill bits, the carbide nozzles also can clean stone chips in the well bottom with drilling liquid in the working conditions of high pressure, vibration, sand and slurry impacting during oil and natural gas prospecting. Carbide nozzles also have hydraulic rock fragmentation effect. Conventional nozzle is cylindrical; it can produce a balanced pressure distribution in the rock surface.

Types of the carbide nozzles

There are two main types of the carbide nozzles for the drill bits. One is with thread, and the other is without thread. Carbide nozzles without thread are mainly used on the roller bit, carbide nozzles with thread are applied mostly on the PDC drill bit. According to different handling tool wrench, there are 6 types threaded nozzles for PDC bits:

1. Cross groove thread nozzles

2. Plum blossom type thread nozzles

3. Outer hexagonal thread nozzles

4. Internal hexagonal thread nozzles

5. Y type (3 slot/grooves) thread nozzles

6. gear wheel drill bit nozzles and press fracturing nozzles.

We can not only produce standard tungsten carbide nozzle, we also be able to produce the customized nozzles according to the drawings or samples.
