HDD Rock Hole Drill 14 Rock Hole Drill with tri-cone drill bit for horizontal directional drilling

HDD Rock Hole Drill 14 Rock Hole Drill with tri-cone drill bit for horizontal directional drilling

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.

Structural features
1. Journal bearings. Hard-faced head bearing surface. The tapered bearing is inlaid with anti-friction alloy and then plated with silver. The bearing capacity and anti-seize ability are greatly improved.
2. The O-ring seal adopts more wear-resistant and highly saturated nitrile rubber, which increases the sealing section, and the precise design of the sealing flange in the conical sealing area improves the reliability of the seal.
3. The drill bearing can adopt ball lock or ring lock. The drill bit with lock ring bearing can bear higher bit weight, the drill bit with ball bearing
Can be used for high-speed drilling.
4. All-rubber compensator is used to limit the pressure difference and prevent the drilling fluid from entering into the lubrication
System, which provides a good lubrication guarantee for the bearing system.
5. New grease is used, which can withstand high temperature up to 250°C.
6. The use of high-strength, high-toughness cemented carbide briquette, combined with optimized briquette number and row number, exposure height and special-shaped briquette, give full play to the high wear resistance and excellent cutting ability of the blade. For steel tooth drills, the tooth surface adopts new wear-resistant materials for hard surface treatment, which prolongs the service life of the cutting structure while still maintaining a high mechanical drilling speed.

The perfect welding process prevents damage to the seal and bearing system due to over-jumping. The bit body adopts a spiral design, which has good performance of stable sand return, improves the opening speed, and reduces the repeated rock breaking by the cone.

Warn:
1. Please select the applicable formula and parameters according to the instructions.
2. Carefully check the appearance of the drill bit, check the thread end face of the drill bit, whether there is the serial number on the packing box and the certificate.
3. The bottom hole must be clean, and the drill bit cannot be used for long reaming.
4. The drilling process must run smoothly, and if any abnormal jump is found, timely analysis and effective measures should be taken
5. The drill bit should be stored in a dry, well-ventilated room with a temperature of 10-33℃, and avoid sun and rain. Stored under these conditions, the quality of the drill bit is guaranteed for 4 years.

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.
