Replaceable Hole Opener/HDD reamer bit's introduction
Replaceable teeth wheel rock reamer suitable for large rigs trenchless pipe laying large diameter trenchless construction, suitable for a variety of rock formations, reaming diameter range up Φ300-2200mm
Wheel body and the body connection reliable, easy disassembly, does not require large-scale special hydraulic equipment, artificial wrench can be convenient to replace the wheel body.
The same body can be reused, you can also install different specifications of the wheel, under normal circumstances can be replaced four different size of the wheel body, which can be carried out with a body of four sizes aperture hole construction, greatly saving construction costs
Horizontal Directional Drilling hole openers are also known as HDD reamers which used to enlargethe pilot hole in Horizontal Directional Drilling (HDD).HDD is used in trenching and excavating is notpractical. This drilling technology allows for a steerable trench-less way to underground.
There are three stages:
a.The first stage is to drill a small diameter pilot hole.
b.The second stage is to enlarge the hole with a larger diameter cutting tool called an HDD Reamers, Rock Reamer or Hole Opener.
c.The thirdstage is inserting the casing pipe or other product into the enlarged hole.

HDD hole opener drilling bits for hard rocks
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
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.
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.
2. Gauge Structure
With active cutting gauge protection inserts on bit body, the bit has good gauge protection and up drill capability.
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.
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.
5. Product Application
It is suitable for sidetracking, deep well drilling and old well
|Big Reamer & Piling Bit|
|Cutting Structure||The reamer always have multi-cones. Bit cones are splited from tricone bits and welded to build a new big diameter bit. The pilot is three cone bit.|
|Product Application||Bigger diameter for piling in construction field, bridge construction, super highway construction, railway construction etc. This kind of bits are suitable for different complex formation, shales, limestone, cobblestone, dolomite, chert, etc.|
|Main Type Available||Regular Bit Diameters: 28 ",32",36",38", etc, and any diameters can be customized, maximum diameter is 1600mm.|
Single cone bit is a kind of deceleration bit, which is the speed of cone is smaller than the speed of drill, mainly disorderly cutting broken rock. It is suitable for old well sidetracking and deepening the slim hole drilling operation under high rotary speed and drilling pressure.
1. Its application field is wide, not only suitable for side drilling, and can be used in deep well.
2. Work torque is lower than PDC bit in the same drilling pressure and formation condition. It can reduce the small size hole expansion buckling problems, so that avoid down hole accidents.
3. Single cone bit has advantages of both three cone bit and PDC bit, and make up the disadvantages of both. It is more suitable for large plastic formation than three cone bit, also can be applied to hard interlayer which PDC bit can not deal with other complex formation.
4. It can realize high speed and special drilling with down hole motor.
