Product Description 6 3/4" IADC 537 Tricone Tooth Bit Three Rotating Cones Drill Bits Product Description Roller Cone Bits have conical cutters or cones with steel tooth or tungsten carbide buttons around them.As the drill string is rotated,the bit cones roll along the bottom of the borehole in a circular motion.As they roll,new teeth come in contact with the bottom of the hole,chipping the formation below and around the bit tooth.Air or drilling fluid life the crushed rock chips from the bottom of the hole and up the annulus. As rotation continues,another tooth makes contact with the bottom of the hole and creates new rock chips,thus,the process is continuous.Premium tungsten carbide insert (TCI) bits and milled tooth (MT) bits are needed to be designed to withstand high temperatures and endure long running times while drilling through soft to ultra hard formations.Tricone Drill Bit is an ideal solution from soft to hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.The medium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard for mations. The HSN rubber O-ring provides adequate sealing for bearing durability IADCRock formationWOB (KN/mm)PRM(r/min) 417/427/437Low compressive strength, high drill-ability and extremely soft formation, like shale, clay, sandstone, conglomerate etc 0.35~0.90 140~70 447Low compressive strength, high drill-ability and soft formation, like shale, clay, sandstone, soft limestone, salt rock, plaster etc. 0.35~1.00 140~60 517Low compressive strength, high drill-ability and soft formation, like shale, clay, sandstone, soft limestone, salt rock, etc 0.35~1.05 120~50 527Soft formation with low compressive, like Low compressive strength, high drill-ability and soft formation, like shale, clay, sandstone, soft limestone, salt rock, anhydrite etc. 0.35~1.05 120~50 537/547Low compressive strength, medium hard formation with hard abrasive interlayer, like Hard shale, anhydrite, soft limestone, sandstone, dolomite with mezzanine, etc. 0.50~1.05 110~40 617/627High compressive strength, medium hard and thick hard interlayer, like hard shale, limestone, sandstone, dolomite, etc. 0.50~1.05 80~40 637/737High compressive strength, medium hard and high abrasive formation, like limestone, dolomite, sandstone, chert, etc. 0.7~1.20 70~40 Similar products Basical SpecificationnamePDC drill bits for oil water well drillingdiameter81/2inchblade number5body typesteel bodyNo.of Nozzles5primary cutter size1608connection thread41/2" API Reg pinOperating parameterRPM(r/m)60~300WOB(KN/mm)5~25Formationsoft to medium hard rock formationCompany ProfileWe shandong yacheng petroleum technology are established in 2003 year, located in Dongying city, shengli oilfield,which is second largest oilfield of China.
