High quality rock drilling tools reamer drill cone reamer hdd drilling tool
Introduction:
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.
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 the 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. The hard surface 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.
