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.

Product parameters

Used in

The hob hole opener is the most effective tool for handling various large-diameter piles in hard rock and gravel strata, and isolated stones. It has unique properties and can greatly reduce the economic benefits of construction costs.

Advantages

The replaceable hob hole-cutter is forged from high quality alloy steel with good weldability. The high tensile strength after modulation can meet the tensile requirements of large tonnage drilling RIGS. Reliable connection between wheel body and valve body, convenient loading and unloading, do not need large special hydraulic equipment. A manual spanner is enough for on-site replacement.
