Grade drill bit hole opener horizontal directional drill hdd hole opener reamer drill bit
Application:
Large-diameter assembled bit is widely used in construction,
bridge, highway and railway construction. This series of bits are
suitable to various kinds of strata including shale, limestone,
cobblestone, dolomite and conglomerate.
1.Suitable for medium to medium hard formation of high Crushing
Resistanc (hard shale,sands,etc.)
2.Bit bearing is non-sealed roller bearing.
3.Hardfacing is applied on the shirttail,and carbide inserts for
gage protection are pressed into the head OD.
4.Cone gage surface is reinforce with carbide compacts.
Cutting Structure:
In response to the characteristics that inserts in different areas
on the cone have different cutting actions, conical inserts are
placed in permanent contact area and wedge inserts are placed in
alternative contact area so that the drilling efficiency is greatly
improved. Wear resistance of cutting structure is enhanced by
setting diamond inserts in the permanent contact area of the cone
where inserts are severely worn. Tungsten carbide inserts are
placed on cone top face to protect cone body from abrasive erosion.
Gauge Structure:
With active cutting gauge protection inserts on bit body, the bit
has good gauge protection and up drill capability.
Bearing Structure:
High precision journal bearing. Balls lock the cone.Hardface heard
bearing surface. Cone bearing inlaid with friction-reducing alloy.
Abrasion resistance and seizure resistance of the bearing are
improved. Compared with three cone bit, the leg bearing is bigger,
so it can receive higher WOB and high reliability.
Hydraulic Design:
Small angled watercourse design increased the shirttail thickness
and can effectively prevent the watercourse erosion.Optirnized
hydraulics structure improves the clearing capability and increases
ROP.
Product name: | HDD Drilling Tools |
Origin: | Hebei china |
Material: | Carbide |
Use: | Drilling |
Application: | HDD project, drilling |
Bearing type: | Metal sealed bearings |
Available sizes: | 6" (152.4mm)~78" (1981.2mm) |

Used in:
The Rock Reamer with replaceable cutter was developed for larger
diameter HDD projects where extended life downhole is critical. The
larger bearings and cutters dramatically extend the downhole life
over smaller, conventional-style cutters. The replaceable cutter
sets are available in both TCI and Milled Tooth styles to match
your formation. All bit’s bodies have three-eight cutters and can
open three different hole sizes.

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.
