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.
