The main structure features:
Our company can provide 220--1600mm HDD rock reamer with roller cones. The roller cone reamer fit for all sorts of rock formation.
The Cone bearing is designed with metal seal or o-ring seal. IADC117--737 tooth type is available for different formation. Cone Lock is used for preventing cone falling off when bearing failed.
1. Horizontal Directional Drilling
Directional drilling (or slant drilling) is the practice of drilling non-vertical wells. It can be broken down into three main groups: oilfield directional drilling, utility installation directional drilling (horizontal directional drilling), directional boring, and surface in seam (SIS), which horizontally intersects a vertical well target to extract coal bed methane. - wikipedia
2.What is HDD?
Horizontal Directional Drilling is a trenchless method of installing piping and cable systems underground in a shallow arc along a predetermined path by the use of highly specialized drilling equipment. Installing piping, conduit and cables underground via HDD is becoming the preferred method of installation as traditional trenching and excavating becomes non-practical and sometimes difficult due to terrain.
3.Benefits of HDD
HDD provides a host of benefits reducing environmental disturbances, reducing ecological impact, and contamination is virtually eliminated from the jobsite once compared to the traditional open cut installation methods. Noise pollution is minimized and speed of work is faster.

4 .The main structure features:
The Rock Reamer with replaceable cutter was developed for large diameter HDD projects where extended life downhole is critical. The larger bearing 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 fit for all sorts of rock formation. All bit's bodies have three-six cutters and can open four different hole sizes.
All cutters bearing is metal sealed. Cutters lock is used for preventing cutter failing off.
400-2000mm hole opener are available.
