About this product

Product information from the supplier.

The 12 1/4” (311.1mm) IADC 517 Insert Tooth Tricone Drill Bit is a high-performance engineering solution specifically designed for the oilfield and energy sectors. Engineered for soft formations with low compressive strength—such as mudstone, gypsum, salinastone, and soft shale—this bit utilizes advanced tungsten carbide inserts to maximize penetration rates while maintaining exceptional structural integrity under demanding downhole conditions.

Featuring a sophisticated three-cone rotating assembly and a precision-engineered bearing system, this tricone bit efficiently crushes and shears geological formations. The integration of high-performance seals and specialized lubrication ensures that the tool withstands extreme friction and high temperatures, providing operators with a reliable, long-lasting tool that reduces downtime and optimizes drilling efficiency in diverse mining and energy environments.

Frequently Asked Questions

Q: What are the ideal formations for the IADC 517 Tricone Bit?

This bit is specifically engineered for soft formations with low compressive strength, including mudstone, gypsum, salinastone, soft shale, and soft limestone.

Q: How should I manage WOB and RPM during operation?

Recommended RPM is 60-140 and WOB is 0.35-1.0. Note that the upper limits of both parameters should not be used simultaneously to avoid premature wear.

Q: What is the correct procedure for starting a new drill bit?

Lower the bit gently; once contact is made, use light pressure (5-15kN) and low speed (60r/min) for 30 minutes before gradually increasing to normal operating parameters.

Q: How should these drill bits be stored to ensure longevity?

Bits should be stored indoors in a dry, ventilated area between 10-30°C, protected from direct sunlight and rain.

Q: What is the warranty period for the Tricone Drill Bit?

Our Tricone Drill Bits come with a comprehensive guarantee period of three years, provided they are operated within recommended parameters.

Q: Can this bit be used for hard rock drilling?

No, the IADC 517 is designed for soft formations. For hard rock, we recommend our PDC bits or Steel Tooth Tricone bits depending on the specific rock compressive strength.
