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.

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 can be quoted with new/unused surplus or used Steel Tooth or TCI Cutters Hole Openers.

At some point it may be necessary to increase the size of a pre-drilled hole to a larger diameter or to drill large diameter holes. Hole opener bits are designed specifically for this purpose. Bits are custom manufactured in a wide range of styles to meet field requirements. A custom hole opener is an effective way of enlarging holes, hence the name "Hole Opener".
The Hole Opener Advantage
Straighter Holes - By drilling a smaller hole with a "pilot" bit, then attaching that said bit onto the bottom of the the hole opener. The hole opener will follow the path of the hole drilled by the smaller bit.
Larger Holes with Smaller Rigs - By drilling a hole in stages, larger holes can be drilled with smaller rigs. A smaller hole requires less power.
Replacing Cutters and Cutting Cost - On most Hole Opener designs, the cutters can be easily replaced. The cost to replace a cutter is a fraction of the cost to replace a large tricone rock bit.
Cost of Large Rock Bits - Larger diameter rock bits not only cost a lot, they can be difficult to find. A more economic solution is to use a hole opener that uses smaller tricone rock bit segments..
Flexability - Hole Openers can be fabricated in just about any size, and can be configured to drill through any formation.
Operational Considerations
Drilling Weight - The choice of drilling weight is determined based on the recommendations of the bit manufacturer and the number of cutters on the hole opener.
Number of Cutters - The number of cutters placed on a hole opener is governed by the following facts:
1.Maximum number which will fit around the perimeter.
2.The greater the number of cutters, the less the weight, which therefore reduces the penetration rate.
3.In softer formations, less weight is needed to penetrate.
4.The greater the number of cutters, the smoother the tool will run.
5.The greater the number of cutters, the greater the cost.
6.The greater the number of cutters, the longer the cutters will last
Rotary Speed - Maximum speed is determined by the manufacturer's recommendation and the calculation to account for the linear distance the cutter is moving per revolution.
Hole Cleaning - A frequently over looked point of hole opener operation is hole cleaning. The volume of cuttings to remove from a hole increase by a squared factor with an increase in hole diameter.

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.
