PDC Bit is a very popular drilling bits in mining and water well drilling, it is design for soft formation and have fast drilling footage speed in soft formation when compared with carbide bit and milled teeth Tricone Bit. Some customers feedback the PDC bit water hole is too small and ask whether can relarge the water hole, answer is can relarge but the efficiency is not so good as the regulare size water hole. First we talk about the function of the water hole of PDC Drill Bit. Water hole's first function is to flow out the small stone or waste when drilling, second is to cooling the PDC Cutter when drilling. If the water hole is too large, there will have no water pressure, then the mud will pack the PDC Cutters and more mud will stay there then will stuck. When it is stuck when you drill holes, please try to enlarge the mud pump volume or water pressure, then the small stone or waste will be rushed out then the stuck problem will be improved.
