The replaceable hob reamer is forged from high quality alloy steel with good weldability. After modulation treatment, the tensile strength is high, which can meet the tensile requirements of large-tonnage drilling rigs. Reliable connection between wheel body and valve body, easy to disassemble and assemble, do not need large special hydraulic equipment, manual wrench can, easy to replace on site.
PANGOLIN hob rock hole opener ranging from 16" to 70" that is divided into two types: MT cutter and Welding cutter, and is apply to various compressive strenght of the formation. The procduct is used for zhe reaming of the oil, gas, petrochemical, sewage, power and fiber optic pipelines in the no-dig horizontal directional drilling.
The larger bearings and cutters dramatically extend the downhole life over smaller conventional-style cutters. The replaceable cutter sets are available in both TCI and Milled Tooth styles to match your formation. All bit's bodies have three-six cutters and can open three different hole sizes.

Hob drill is to deal with all kinds of large diameter pile in hard rock formations and gravel stratum, solitary stone most effective tool, has unique properties, can greatly reduce the construction costs of the economic benefits.
The roller body can be used multiple times, and it is convenient and quick to replace the roller. There are three types of rollers: type A, type B and type C, and different reaming diameters can be achieved through adjustment.
The unique multi-stage anti-off 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 hob wheel 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.
