Fixed Diameter Hole Opener is used for enlarging the surface hole which drilled by cone bit in advance, or connected above the cone bit. It applies to Onshore and Offshore oilfield.
Cutter type:
SM: Soft to medium formation
MH: Medium to hard formation
XH: Hard formation.
Size: 200-2000mm Suitable for soft soil, hard soil and strong-mantle rock, sand and medium-to-very hard soil. Connection with drill rod: Direct connection with drill rod Octagonal connection Connection with laid pipe: Within or without swivel -
Drill Bits
Features: 1.The product is used for the reaming of the oil, gas, petrochemical, sewage, power and fiber optic pipelines in the no-dig horizontal directional drilling. 2.Directional crossing operation is widely used in unexcavated project. 3.Small torque force can be applied to hole opening with drilling machine. 4.Hole opener includes body and the cutter. 4 different types of cutter can be assembled to the body in one size for opening the hole in 4 sizes. 5.Cutter can be divided into MT type used in soft formation and TCI type used in hard formation.

Description: Horizontal Hole openers, also known as HDD reamer, are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes. HDD is used when trenching and excavating is not practical. This drilling technology allows for a steerable trenchless way to drill underground. There are three stages, the first stage is to drill a small diameter pilot hole. The second stage is enlarge the hole with a larger diameter cutting tool called an HDD Reamer, Rock Reamer or Hole Opener. The third stage is inserting the casing pipe or other product into the enlarged hole.

Hole Openers are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes. A Hole Opener is sometimes referred to as a Reamer. Roller cone hole openers are specifically designed for horizontal, rock drilling applications. Extensive tool performance experience combined with the pooling of hole opener expertise from various industries (directional crossing, mining and oil field) has aided in designing and manufacturing a proven line of horizontal hole openers for the trenchless construction industry. Our approach to tool application analysis and tool set-up recommendations includes cutting structure selection, hydraulics and torque and drag analysis. This comprehensive approach enables us and the contractor to minimize the number of reaming passes and optimize hole opener performance.
