152.4mm Trenchless HDD Hole Opener Drilling Tools

34LY537 Forged assembly Trenchless horizontal directional hole opener bit for water well drilling

Application scenario:
Large-diameter assembled drill bits are widely used in construction, bridge, highway and railway construction. This series of drill bits are suitable for shale, limestone, cobblestone, dolomite, conglomerate and other formations.
1. Suitable for medium to medium hard formations with high fracture resistance(Hard shale, sandstone, etc.)
2. The drill bearing is a non-sealed roller bearing.
3. The tip of the palm is welded with hard surface, and the carbide blade is protected by the gaugeIs pressed into the head OD.
4. The surface of the cone gauge is reinforced with cemented carbide press blocks.

Product structure:
1. Cutting structure
In view of the different characteristics of the cutting action of the blades in different areas on the cone, the tapered blades are placed in the permanent contact area, and the wedge-shaped blades are placed in the alternating contact area, which greatly improves the drilling efficiency. By arranging a diamond blade in the permanent contact area of the cone where the blade is severely worn, the wear resistance of the cutting structure is enhanced. The tungsten carbide blade is placed on the top surface of the cone to protect the cone from abrasion.
2. Instrument structure
The drill bit adopts active cutting volume protection insert, which has good gauge protection and drilling ability.
3. Bearing structure
High-precision journal bearings. The ball locks the cone. Hardface hears the bearing surface. The tapered bearing is inlaid with anti-friction alloy. Improve the wear resistance and seizure resistance of the bearing. Compared with the tri-cone bit, the outrigger bearing is larger, so higher WOB and higher reliability can be obtained.
4. Hydraulic design
The small-angle waterway design increases the thickness of the tip of the palm and effectively prevents the waterway from scouring.​​​ Optimize the hydraulic structure, improve the cleaning ability, and increase the speed of penetration.

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.
