Φ190D153 Φ190Φ1131-18 Gas drainage hole Polycrystalline diamond compact(PDC)is a new type of super hard material synthesized under high temperature and high pressure conditions using medium high cobalt hard alloy and synthetic diamond polycrystals.The drill bit made from it have significant advantages over traditional hard alloy drill bits, with a lifespan 10-30 times longer and an efficiency over 50%higher.
Product features
★ High wear resistance,impact resistance,strong toughness,no special requirements for equipment.
★ Multiple cutting free surfaces,high drilling efficiency,long service life and strong dill bit diameter retention.
★ Short drilling time,low labor intensity for workers and high overall efficiency.
The efficient combination dill bit is used in conjunction with the efficient spiral drilling rod.The dill bit base is made of high-quality alloy structural steel,and the hard alloy cutting heads used are all imported materials.The alloy powder is screened through advanced technology,which greatly improves its hardness and wear resistance,providing strong guarantee for the effective drilling and long-distance drilling o the efficient combination drill bit.
