Customizable HDD drill bit hole opener assembly well drilling tool
Advantages:
1.Cutting structure
In view of the different cutting characteristics of the inserts in
different parts of the cone, the cone inserts are placed in the
permanent contact area, and the wedge inserts are placed in the
alternating contact area, which greatly improves the drilling
efficiency. The diamond insert is provided in the permanent contact
area of the cone to improve the wear resistance of the cutting
structure, and the insert is worn seriously in this area. Place
tungsten carbide inserts on the top surface of the cone to protect
the cone from abrasion.
2. Table structure
The cutting body is provided with active cutting protection
inserts, so that the drill bit has good cutting protection and
drilling ability.
3. Bearing structure
High-precision journal bearings. The ball locks the cone. Hard
surface bearing surface. Tapered bearings with friction-reducing
alloys. Improve the wear resistance and bite of the bearing.
Compared with the tri-cone bit, the leg bearing of the tri-cone bit
is larger, which can withstand higher drilling weight and higher
reliability.
4. Hydraulic design
The small-angle waterway design increases the thickness of the
shirt hem, which can effectively prevent waterway erosion. Adopt
optirized waterics structure, improve the cleaning ability and ROP.
Features:
1. Suitable for medium to medium hard formations with high
compression resistance (hard shale, sand body, etc.)
2. The bit bearing is an unsealed roller bearing.
3. The edge of the shirt is welded and the carbide insert is
pressed into the outer diameter of the head.
4. The surface of the cone gauge is strengthened with cemented
carbide.
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.

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.
