Factory of oil well tricone drill bits in stock with discounted price IADC: 115 is Steel tooth sealed roller bearing bit with gauge protection for soft formations with low compressive strength. The Compressive Strength of IADC115 bit's details are as following: 0-35 MPA/ 0-5,000 PSI Ground Description: The IADC115 tricone bit is suitable for soft, poorly compacted rocks and unstratifield such as marl limestones, salts, gypsum, and hard coals,poorly compacted clays and sandstones, The tricone bits have type of Tungsten Carbide Insert (TCI) and Mill Tooth (Steel Tooth) according to cutting materials. They are versatile and can cut through many formations type.The mill tooth tricone drill bit is used for soft formations. The TCI rotary tricone bits is used for medium and hard formations. Soft rock formations include unconsolidated sands,clays,soft limestones,redbeds and shale. Medium hard formations include dolomites,limestones,and hard shale,while hard formations include hard shale,while hard formations include hard shale,mudstones,cherty limestones and hard and abrasive formations.| Basical Specification | |

The optimized tooth structure makes the wear-resistant alloy of the tooth surface and the tooth top weld thicket and more aggressive,effectively improving the wear resistance of the tooth and greatly increasing the mechanical drilling speed. Steel tooth bits are rubber sealed for durability and reliability.Using a new welding process, a new welding material is used on the inner and outer teeth surfaces to make the teeth more wear-resistant.
