Hard Rock Drilling Horizontal No Dig HDD Hole Opener
HDD Hole Opener for Hard Rock Drilling Horizontal No - Dig
Introduction
The fixed diameter hole opener is made of tough heat-treated alloy steel for maximum strength. The cutter arm is equipped with a detachable cutter and is hard-faced welded on the valve body. There are three types to choose from: SM type is used for soft to medium formations, MH type is used for medium to hard formations, and XH type is used for hard formations. The hole opener has three or six nozzles, which can be replaced, so that the jet can quickly clean the enlarged hole.
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.
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. 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.
