    Horizontal Directional Drilling Bits are made of tungsten carbide, which can withstand the high temperatures and pressures generated during the drilling process. The drill bits are also coated with diamonds, further enhancing their cutting performance and longevity.

    Horizontal Directional Drilling Bits are commonly used in construction and engineering projects where precision and accuracy are critical, such as drilling holes in walls or floors for electrical wiring or pipes. They can be used with a variety of drilling machines, including handheld drills, drill presses, and specialized machines designed for horizontal drilling.

    Horizontal Directional Drilling Bits are essential tools for many industries and applications, enabling workers to drill through materials quickly and efficiently while maintaining precision and accuracy.

    Designed and developed to meet construction requirements and market demands, our trench-less cone palm can be applied to various formations and drilling tools, providing full coverage for sizes ranging from 8-1/2 to 12-1/4 inches.

    Internal structure:
    Adopting steel ball-locking sliding bearings, the bearing surface is welded with wear-resistant alloy, providing high wear-resistant performance and longer service life.
    High-performance rubber sealing structures and metal sealing structures enhance the life and reliability of the entire sealing system.
    High-performance environmental protection grease and a bearing structure equipped with an oil storage and pressure compensation system improve the working life of the bearings.
    Carbide inserts with high strength and toughness can enhance insert impact resistance and reduce insert breakage rates.
    An optimized cutting structure, insert exposed height, quantity, and shape strengthen drilling coverage, fully leveraging the advantages of trench-less reamers.

    At the same time, the product combines the working condition of horizontal drilling with the trench-less cone and design a special palm back stabbing structure. Grand can develop special models of products according to customers' needs.
