ODEX drilling tools for sale

The concentric drill bit consists of three parts: the center guide drill bit, the pipe shoe and the centering ring drill bit. The center guide drill bit is used to drill the center of the hole and pull the drill string, and together with the disposable centering ring drill bit, it forms a complete drilling drill bit. The pipe shoe is connected to a casing by welding or threading, and is pulled into the hole with the impact of the hammer and the center guide drill bit. The centering ring drill bit and the pipe shoe are combined and locked to the tail handle of the hammer by the center guide drill bit. During drilling, the ring drill bit drills out the part of the casing that exceeds the outer diameter of the center guide drill bit required for the casing to enter the hole. The shoulder of the guide drill bit supports the shoulder of the pipe shoe. The impact energy of the down-the-hole impactor is transmitted and broken through the guide drill bit and the ring drill bit, and part of the impact energy is used to push the casing forward. After drilling and hole guarding are completed, the center guide drill bit and the drill string are retrieved by gently reversing the buckle connection to unlock it. The ring drill bit remains in the hole and is only removed together when the casing is pulled out. Our concentric follow-up drilling tools are designed for use in loose rock formations.They can drill holes of various sizes and can be used for drilling and protecting holes simultaneously. The dust removal groove is built into the casing and the pipe shoe to ensure good sealing at the bottom of the hole, minimizing the possibility of blockage caused by scattered objects around the hole. This drilling tool makes it easy to follow the casing, simplifies the equipment, and is easy to operate. It is suitable for many purposes, such as micropiling, pillars, anchoring, beach construction and horizontal drilling.
