Mining Well Drilling 22 Inches 24 Inches HDD Hole Opener

22 / 24 Inches Diameter HDD Hole Opener For Horizontal Hole Drilling

Product parameters

Introduction

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.

Advantages

1. Cutting Structure
In response to the characteristics that inserts in different areas on the cone have different cutting actions, conical inserts are placed in permanent contact area and wedge inserts are placed in alternative contact area so that the drilling efficiency is greatly improved. Wear resistance of cutting structure is enhanced by setting diamond inserts in the permanent contact area of the cone where inserts are severely worn. Tungsten carbide inserts are placed on cone top face to protect cone body from abrasive erosion.
2. Gauge Structure
With active cutting gauge protection inserts on bit body, the bit has good gauge protection and up drill capability.
3.Bearing Structure
High precision journal bearing. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy. Abrasion resistance and seizure resistance of the bearing are improved. Compared with three cone bit, the leg bearing is bigger, so it can receive higher WOB and high reliability.
4. Product Application
It is suitable for sidetracking, deep well drilling and old well

Features

1) Drill Bit Connection made according to API standard.
2) We can adjust the bit size according to your rig.
3) The best result can be obtained by using the steel-tooth bit in the soft stratum.

Used in
