Horizontal Directional Drilling HDD Rock HOB Hole Opener
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.
The unique multi-stage anti-disengagement interlock device prevents the hob from tripping when the drill bit is empty, and prevents the hob shell from falling when the bearing is damaged.
The roll body is inlaid with large-diameter cemented carbide, which has a good rock breaking effect; the bearing has a large diameter and strong impact resistance. Using metal seal, long service life.
Advantages
The replaceable hob 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.

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.
Used in
The Rock Reamer with replaceable cutter was developed for larger diameter HDD projects where extended life downhole is critical. 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-eight cutters and can open three different hole sizes.
