Horizontal Directional Drilling 12" HDD Hole Opener

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.

Features

1. The edge of the shirt is welded and the carbide insert is pressed into the outer diameter of the head.
2. Suitable for medium to medium hard formations with high compression resistance (hard shale, sand body, etc.)
3. The bit bearing is an unsealed roller bearing.
4. The surface of the cone gauge is strengthened with cemented carbide.

Product parameters

Used in

Apply to PDC Rock Reamer, Construction, Water Drilling, Mining, Horizontal Directional Drilling, Geothermal and Environ-mental.

Advantages

1. Cutting structure
In view of the different cutting characteristics of the blades in different parts of the cone, placing the cone blade in the permanent contact area and inserting the wedge-shaped blade in the alternating contact area can greatly improve the drilling efficiency. The diamond blade is arranged in the permanent contact area of the cone to improve the wear resistance of the cutting structure, and the blade is severely worn in this area. Place the tungsten carbide blade on the top surface of the cone to prevent the cone from wearing.

2. Hydraulic design
The small-angle waterway design increases the thickness of the shirt hem, which can effectively prevent waterway erosion. Use optimized water structure to improve cleaning ability and ROP.

3. Product application
Suitable for sidetracking, deep wells and old wells
