HDD Reamer Hole Opener
HDD Reamer Hole Opener Of Directional Drilling Tools
Introduction
The Fixed Diameter Hole Opener is made of tough heat treated alloy
steel for maximum strength. Cutter arms, equipped with removable
cutter, are hardfaced and welded on body. Cutters are available in
three types: type SM for soft to medium formation, type MH for
medium to hard formation and type XH for hard formation. The hole
openers have three or six jet tubes with replaceable nozzles, so
that jet streams quickly clean the enlarged hole.
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. Table structure
The cutting body is provided with active cutting protection
inserts, so that the drill bit has good cutting protection and
drilling ability.
3. 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.
4. Hydraulic design
The small-angle waterway design increases the thickness of the
shirt hem, which can effectively prevent waterway erosion. Adopt
optirized waterics structure, improve the cleaning ability and ROP.
5. Product application
Suitable for sidetracking, deep wells and old wells

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.
4. The surface of the cone gauge is strengthened with cemented
carbide.
