16 Inches HOB Hole Opener

Product Description

Trenchless Horizental Drilling Replaceable HOB Hole Opener



The specifications of pangolin hob hole openers range from 16" to 70", and are divided into two types: MT knife and welding knife, which are suitable for various compressive strength of the formation. This product is used for the reaming of oil, natural gas, petrochemical, sewage, power and fiber optic pipelines in trenchless horizontal directional drilling.

Larger bearings and smaller conventional tools significantly extend downhole service life. Interchangeable cutters are set in TCI and milling gear styles to match your shaping. All drill bits have 3-6 tools and can open 3 holes of different sizes.




The unique multi-stage anti-disengagement interlocking device prevents the hob from tripping when the drill bit is empty, and prevents the hob shell from falling off when the bearing is damaged.
The roller body is inlaid with a large-diameter hard alloy, which has a good rock-breaking effect; the bearing diameter is large, and the impact resistance is strong; the metal seal is used, and the service life is long.




The replaceable hob hole opener is forged from high-quality alloy steel with good weldability. After modulation, the tensile strength is high, which can meet the tensile requirements of large-tonnage drilling rigs. The connection between the wheel body and the valve body is reliable, and the loading and unloading are convenient, and no large-scale special hydraulic equipment is needed. A manual wrench is enough, which is convenient for on-site replacement.
