Raw Material Cemented Carbide Threaded Nozzle For Water Cooling And Drilling
Raw Material Cemented Carbide Threading Nozzles Used For Water Cooling And The Drilling
Product Description
Cemented carbide nozzles are mostly used for water cooling and slurry scouring of the drill bit during the drilling. The size and the form of the water holes should be designed selectively according to the different geological conditions and the flow rate. The nozzles are normally divided into two kinds according to the varied drill bits and the conversion requirement, one of these is with thread and another without thread. The nozzles without thread are mainly to be used to the PDC drill bits.
