24" Reamer Horizontal Directional Drilling Hole Opener
Features
1) Connect the drill bit according to API standards.
2) We can adjust the bit size according to your drilling rig.
3) The best effect can be achieved by using steel tooth drill bits
in soft formations.
Advantages
1. Cutting Structure
In view of the different characteristics of the cutting action of
the inserts in different parts of the cone, the tapered inserts are
placed in the permanent contact area, and the wedge-shaped inserts
are placed in the alternate contact area, which greatly improves
the drilling efficiency. The wear resistance of the cutting
structure is improved by arranging diamond inserts in the permanent
contact area of the cone. The inserts in this area are seriously
worn. A tungsten carbide insert is placed on the top surface of the
cone to protect the cone from abrasion.
2. Gauge Structure
With active cutting gauge protection inserts on bit body, the bit
has good gauge protection and up drill capability.
3. Hydraulic Design
Small angled watercourse design increased the shirttail thickness
and can effectively prevent the watercourse erosion.Optirnized
hydraulics structure improves the clearing capability and increases
ROP.

Introduction
The reamer bits mainly consists of more than 3 cones.cutting
structure with premium tungsten carbide
hardfacing o premium tungsten carbide insert of formulas and new
techniques is utilized,and increases
wear-resistance capability of reamer.
1. Main sizes: Generally bit diameters:
311mm,346mm,500mm,800mm,900mm and so on, all sizes could be
customized by requirements.
2. Application: Hole opener can enlarge a small well hole to bigger
diameter in construction field,bridge construction,
super highway construction,railway construction etc. This kind of
bits are suitbale for different complex
formation,shales,limestone,cobblestone and so on.
3. Cutting structure: the hole opener always have multi-cones.Bit
cones are splited from tricone bits and welded
to bulid a big diameter bit, the pilot is attched with hole opener.
Used in
Apply to Construction, Water Drilling, Mining, Horizontal
Directional Drilling, Geothermal and Environ-mental.
