The 17 1/2'' 444mm IADC 117 Steel Tooth Milled Tooth Tricone Bit is one of our flagship products, tailored for use in geothermal and water well drilling applications. Built to withstand soft to medium formations, it ensures fast and efficient drilling operations while maintaining long-term reliability and cost-effectiveness.
The 17 1/2'' IADC 117 Steel Tooth Milled Tooth Tricone Bit from HJ Bit is engineered for high performance in geothermal, oil, and water well drilling applications. With a diameter of 444mm, this tricone bit is designed to handle extremely soft to medium formations with varying hardness. Whether you're drilling in clay, mudstone, soft shale, or anhydrite, this bit's robust steel tooth design and optimized geometry ensure excellent penetration rates and long service life.
The bit is equipped with high-quality milled steel teeth that are ideal for soft to medium formations, providing efficient cutting and extended durability. It also features elastomer-sealed bearings, which help prevent contaminants from entering the bearing area, reducing the likelihood of failure and ensuring smooth operation even in challenging environments.
For added protection, the bit is designed with gauge protection to reduce wear and improve the stability of the bit during operations, and three jet nozzles ensure effective fluid circulation, optimizing cleaning and cooling during the drilling process. With these advanced features, the HJ Bit IADC 117 Steel Tooth Tricone Bit is an essential tool for tough and demanding drilling projects.
Steel tooth drills are suitable for extremely soft formations with low compressive strength and high drillability such as clay, mudstone, chalk, etc. They are also suitable for medium strata with high compressive strength, such as soft shale, anhydrite, medium soft limestone, medium soft sandstone. Medium stratum with a hard interlayer.
