HDD Rock Reamer Hole Opener Used In Mining Machine



1. Cutting structure
In view of the cutting characteristics of the tooth piece in different parts of the cone, the cone piece is placed in the permanent contact area, and the wedge piece is placed in the alternating contact area, which greatly improves the drilling efficiency. In order to improve the wear resistance of the cutting structure, a diamond insert is set in the permanent contact area of the cone, and the insert is severely worn in this area. Place a tungsten carbide insert on the top surface of the cone to protect the cone from wear.


2. Table structure
The cutting body is equipped with active cutting protection inserts, so that the drill has good cutting protection and drilling ability.


3. Bearing structure
High-precision bearings" magazine. The ball locks the cone. Hard surface bearing surface. Conical bearings made of friction-reducing alloys. Improve the wear resistance and bite force of the bearing. Compared with tri-cone bits, tri-cone bits have larger leg bearings, which can withstand higher drilling weights and higher reliability.


4. Hydraulic design
The small-angle waterway design increases the thickness of the shirt hem and effectively prevents waterway erosion. Adopt optirized waterics structure to improve cleaning ability and ROP.


5. Product Application
Suitable for sidetracking, deep wells and old wells




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.
