15 1/2 Inch Iadc 537 Rubber Sealed Bearing Tci Tricone Rock Bit For Medium Hard Formation
15 1/2 Inch Iadc 537 Rubber Sealed Bearing Tci Tricone Rock Bit For Medium Hard Formation
Shop the 15 1/2 Inch IADC 537 Rubber Sealed Bearing TCI Tricone Rock Bit for medium-hard formations. We are a factory specializing in manufacturing high-quality drilling tools.
Introduction 1. High-strength and high-toughness carbide teeth are used to improve the impact resistance of the teeth and reduce the tooth breakage rate; 2. The optimally designed tooth row number, tooth number, exposed tooth height and unique alloy tooth shape give full play to the cutting ability and cutting speed of the drill bit; 3. Widely used in petroleum exploration, mining exploration, geothermal wells, hydrological exploration and other fields. Our company can provide specific solutions according to the actual drilling situation, and customize assembled drill bits of any diameter, including large-diameter machine pile drill bits, different types of drill bits, reaming bits, directional drilling bits, etc. Characteristics IADC Specification First Dight 1,2 and 3 designate Steel tooth bits with 1 for soft,2 for medium and 3 for hard formations.4,5,6,7 and8 designate Tungsten Carbide Insert Bits for varying formation hardness with 4 being th softest and 8 the hardest. Second Dight 1,2,3 and 4 are further breakdown of formation with 1 being the softest and the hardest. Third Dight 1.Standard open bearing roller bit 2.Standard open bearing roller bit,air-cooled 3.Standard open bearing roller bit with gauge protection which is defined as carbide inserts in the heel of the cone. 4.Standard roller bearing bit 5.Standard roller bearing bit with gauge protection 6.Standard journal bearing bit 7.Standard journal bearing bit with gauge protection Guidance of Tricone Bit Choice
