About this product

Product information from the supplier.

The 9 7/8” (250.83mm) IADC 517 Insert Tooth Tricone Drill Bit is a high-performance engineering solution specifically designed for oilfield drilling operations. Engineered for reliability in soft formations, this bit utilizes premium tungsten carbide inserts to deliver superior crushing and shearing capabilities, ensuring efficient penetration and maximized drilling speeds in challenging geological environments.

Featuring a robust three-cone rotating assembly and an advanced bearing system, this tool is optimized for low compressive strength formations such as mudstone, gypsum, and soft limestone. By combining precision manufacturing with high-performance seals and lubrication, it withstands extreme downhole loads and high temperatures, reducing downtime and lowering the overall cost per foot for energy and mining projects.

Frequently Asked Questions

Q: Which geological formations are best suited for the IADC 517 Tricone Bit?

The IADC 517 is specifically designed for soft formations with low compressive strength, including mudstone, gypsum, salinastone, soft shale, and soft limestone.

Q: Can I use maximum WOB and maximum RPM simultaneously?

No. According to the operating guidelines, the upper limits of Weight-on-Bit (WOB) and Rotational Speed (RPM) should not be used simultaneously to avoid premature failure.

Q: How should the drill bit be initially lowered into the well?

The bit should be lowered slowly. After contacting the bottom, apply gentle pressure (5-15kN) and a low speed (60r/min) for 30 minutes before gradually increasing to normal parameters.

Q: What is the recommended storage environment for these drill bits?

Drill bits should be stored indoors in a dry, ventilated area protected from sun and rain, with a temperature range between 10°C and 30°C.

Q: How do I choose the correct nozzle for my drilling operation?

Select nozzles based on your specific hydraulic parameters. Ensure that the nozzle hole size grade difference is not too large to prevent erosion of the flow channel.

Q: What should I do if "jump drilling" or abnormal vibrations occur?

If abnormalities such as jump drilling occur, you should immediately analyze the cause and implement effective measures to adjust parameters and ensure smooth operation.
