The 8 1/2 inch IADC 547 tricone drill bit is engineered for medium soft formations with low compressive strength and harder abrasive stringers, including hard shale, hard gypsum, soft limestone, sandstone and dolomite with stringers. It operates within a WOB range of 0.35 - 1.05 and an RPM range of 110 - 40, making it suitable for rigs with variable speed requirements. The bit features rubber sealed bearings for enhanced durability in abrasive conditions.
This model incorporates the supplier’s advances in bottom-hole flow field simulation, profile optimisation and insert arrangement design to reduce torque and improve stability. The tricone configuration ensures balanced drilling, while the sealed bearings extend the bit’s lifespan in challenging formations. Typical for IADC 547 bits, the design prioritises penetration rates in softer formations with intermittent harder layers.
Applications for this bit span oil and gas exploration, mining, geothermal drilling and construction. Buyers should match the bit’s IADC classification to their formation’s hardness and abrasiveness, as the 547 code indicates a focus on medium soft conditions with some abrasive content. The supplier’s wooden case packaging with gauge protection ensures safe transit, but buyers should confirm handling procedures to avoid damage.

Prior to ordering, confirm the bit’s IADC 547 classification aligns with your formation’s hardness and abrasiveness, as this directly impacts drilling efficiency. Verify the WOB and RPM ranges match your rig’s specifications to avoid operational issues. Request the supplier’s technical data sheet to cross-check the bit’s compatibility with your project requirements.
Logistics details should include the packaging type (wooden case with gauge protection), shipping method and estimated lead time. Clarify the Incoterms, such as FOB or CFR, to determine responsibility for transit costs and risks. Payment terms, including L/C or T/T, should be agreed upon in advance to prevent delays in shipment and customs clearance.
Upon delivery, inspect the bit for damage to the cutting structure, bearings and threads, as mishandling during transit can compromise performance. Request a certificate of conformity or third-party inspection report to ensure the bit meets IADC standards. For critical projects, consider a pre-shipment inspection to verify the bit’s condition before it leaves the supplier’s facility.
