HDD Hole Openers are universal rock reaming drilling tools in the non-excavation andcrossing construction industry. Our company independently designs and produces tooth wheelpalms, which can produce various types of tooth wheel reamers suitable for various formations.
Journal Bearings, the surface of the tooth palm bearing is welded with a hard alloy layer, andthe tooth wheel bearing is silver plated, improving its load-bearing capacity and anti-bite ability.
Optimize the design of the diversion channel to better discharge rock debris and preventrepeated crushing.
Equipped with a proper guiding belt, the guiding effect is good, and it can smoothly contactthe wellbore wall,reducing the tendency of pipeline trajectory change.
Optimize the welding process to prevent damage to the sealing components caused bywelding overheating.
