Forging HDD Rig HOB Hole Rock Reamer For Open Excavation
Introduction
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.
Features
It can be used multiple times, and it is convenient and quick to change the wheel. The roller is divided into three types of A type, B type and C type, and different diameters of reaming can be realized through adjustment.
Unique multi-stage anti-tripping interlock device can prevent the bit from tripping when the bit is empty, and prevent 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.
