Oil drilling and geological drilling is the most used or cone bit. The cone bit has the effect of rocking, crushing and shearing the formation rock in rotation, so the cone bit can be adapted to soft, medium and hard layers. Especially in the jet cone bit and long nozzle after the emergence of cone bit, the cone drill bit drilling speed greatly improved, is the history of the development of cone bit a major revolution. The cone bit can be divided into teeth (tooth) by tooth type, tooth (bit) (tooth set inlaid with carbide teeth) cone bit; according to the number of teeth can be divided into single cone, double , Three-cone and multi-cone bit. At home and abroad use the most, the most common is the Tricone bit. SPECIFICATIONSIADCWOB(KN/mm)RPM(r/min)Applicable Formations417/4270.3-0.9150-70very Soft formation with low compressive strength and high drillability,such as clay,soft mudstone,shale,salt,loose sands,etc.437/4470.35-0.9150-70very Soft formation with low compressive strength and high drillability,such as clay,soft mudstone,shale,salt,loose sands,etc.515/5250.35-0.9180-60very Soft formation with low compressive strength and high drillability,such as mudstone,salt,soft limestone, sands,etc.517/5270.35-1.0140-50Soft formation with low compressive strength and high drillability,such as  mudstone,salt,soft limestone,sands,etc535/5450.35-1.0150-60medium soft with harder formation, more abrasive streaks,such as hard shale,mudstone,soft limestone,etc.537/5470.4-1.0120-40medium soft with harder formation, more abrasive streaks,such as hard shale,mudstone,soft limestone,etc.617/6270.45-1.190-50medium hard with higher compressive strength as well as thick and hard streaks,such as hard shale,sands,limestone,dolomite,etc.6370.5-1.280-40medium hard with higher compressive strength as well as thick and hard streaks,such as hard shale,sands,limestone,dolomite,etc.7370.7-1.270-40Hard with high abrasiveness such as hard limestone,dolomite,firm sands,etc827/8370.7-1.270-40very hard with high abrasiveness,such as quartzite,quaruzite sand,chert,basalt,granite,etc.FAQQ: Are you a manufacturer or trading company?A: We are a specialized manufacturer. Q: What are your main products, and used for?A: Our products include core barrel, casing, drill rod, drill rig and other drilling parts.They are used for mineral exploration, geological drilling, Q: How about the delivery terms?A: 1.Payment: T/T, L/C, Western Union, Paypal, 30% deposit in advance and rest before delivery2.
