HDDD hole openers for horizontal drilling
Horizontal reamer, also known as HDDD reamer, is used to expand the pilot hole of horizontal directional drilling (HDDD) - HDDD is used when grooves and excavations are not practical. This drilling technique allows drilling underground in a manipulable trenchless manner.
Reaming bit mainly consists of four or more cones. Main cutting tooth is Tungsten Carbide insert tooth and steel tooth welded new-type wear-resistant alloy. High quality tungsten carbide tooth of new formula and new technique increases the service life of reaming bit. The pilot is roller cone bit or drag bit.
Seal and Lubrication
The bearing seal applys high performance O-ring seal or metal sealed bearing and imported lubrication grease special for bit.
It is applied in the big size casing well section, mining and infrastructure building drilling.
