12inches Gas and Oil Water Well For HDD Drilling Hole Opener Reamer 400kg

Introduction:
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 gauge
Is pressed into the head OD.
4. The surface of the cone gauge is reinforced with cemented carbide press blocks.

Product Description:

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.
