Machine Tool Thread Tool 400mm Rock Reamer for HDD Horizontal Directional Drilling Tool

Advantage:
Straight hole-Use a "guided" drill to drill a smaller hole, and then attach the drill to the bottom of the hole opener. The hole saw will follow the path of the hole drilled by the smaller bit.
Larger holes with smaller rigs-By drilling in stages, larger holes can be drilled with smaller rigs. Smaller holes require less power.
Tool replacement and cutting costs-In most hole opener designs, the tool can be easily replaced. The cost of tool replacement is a small part of the cost of replacing a large tri-cone rock drill bit.
The cost of large rock drill bits-Larger diameter rock drill bits are not only expensive, but also difficult to find. A more economical solution is to use a hole opener, which uses a smaller tri-cone rock drill bit.
Flexibility-The hole opener can be manufactured in almost any size and can be configured to drill through any formation.

Applicable field:
Mining, underground exploration, water well drilling, oil and gas well drilling. This type of drill has an optimized bearing design and can work stably under high drilling pressure. The high-quality carbide blade taper gauge has good wear resistance and can extend the service life of the drill. Our goal is to sell the best quality products at the lowest possible price.

Describe:
1. Main size: general drill diameter: 311mm, 346mm, 500mm, 800mm, 900mm, etc., all sizes can be customized according to requirements.
2. Purpose: The hole opener can expand the small borehole to a larger diameter in the construction field, bridge construction, highway construction, railway construction and other fields. This kind of drill bit is suitable for different complex formations, such as shale, limestone, cobblestone, etc.
3. Cutting structure: The hole opener is always multi-cone. The drill bit is a large-diameter drill bit that is welded separately from the tri-cone drill bit, and the hole guide is attached with a hole opener.

FAQ:
1. What is the quality of the drill bit?
A: We have many series of rock drill bits with different quality grades and different prices.
We believe that a suitable tool with a higher cost-effectiveness is the most important. For example, our high-quality rock drill bits are not cost-effective for water well drilling, because water well drilling rigs cannot drive super rock drill bits to their best performance. But for very deep wells, what about high-quality grades? Rock drill bits are cost-effective, even if their prices are much higher. So it’s best to tell us as much as possible about the details of the project, and then we provide suitable solutions and quotations, usually 2 or 3 solutions to choose from.
2. How to send an inquiry?
A: It is best to send us the detailed specifications of the product; it is best to attach some photos for better understanding. If you have no experience in the drilling field, for example, many customers don’t know the IADC code, please feel free to tell us about the applications such as oil/gas/geothermal/HDD/waer/mining, well depth, average rock hardness, and then we will make suggestions and solutions Program.
