Product Specification

HDD reamer rock drill bit and pilot drill bit, reamer, HDD drill tool

Introduction:
HDD rock hole opener ranging from 18”to 66”that with replaceable cutter was developed for HDD projects where extended life downhole is critical. The larger bearings and cutters dramatically extend the downhole life over smaller, conventional-style cutters. The replaceable cutter sets are available in both TCI and Milled Tooth styles to match three formation. Heavy duty bodies can open three sizes of aperture

Features:

Low Torque Hob Rock Hole Opener:

●Lowers drill string torque allowing small rigs to ream in rock formation

●The metal sealing, long service life, can reach 300-400 hours

●Sealed journal bearing cutters are field replaceable while on drill string

●Unique slick body design decreases common repair costs associated with conventional reamers and hole openers

●All cutters gage protected for optimum wear resistance

●Cutters are available in milled tooth for soft to medium rock formation or Tungsten Carbide Inserts for hard rock formation.

●Cutters body having an interlock mechanism does not produce cutters fall

The perfect welding process prevents damage to the seal and bearing system due to over-jumping. The bit body adopts a spiral design, which has good performance of stable sand return, improves the opening speed, and reduces the repeated rock breaking by the cone.

Used in:
The Rock Reamer with replaceable cutter was developed for larger diameter HDD projects where extended life downhole is critical.

FAQ:
1. What is the quality of the drill bit?
A: We have many series of rock drill bits with different quality grades and different prices.
We believe that a suitable tool with a higher cost-effectiveness is the most important. For example, our high-quality rock drill bits are not cost-effective for water well drilling, because water well drilling rigs cannot drive super rock drill bits to their best performance. But for very deep wells, what about high-quality grades? Rock drill bits are cost-effective, even if their prices are much higher. So it’s best to tell us as much as possible about the details of the project, and then we provide suitable solutions and quotations, usually 2 or 3 solutions to choose from.
2. How to send an inquiry?
A: It is best to send us the detailed specifications of the product; it is best to attach some photos for better understanding. If you have no experience in the drilling field, for example, many customers don’t know the IADC code, please feel free to tell us about the applications such as oil/gas/geothermal/HDD/waer/mining, well depth, average rock hardness, and then we will make suggestions and solutions Program.
