China HDD Rock Reamers

Horizontal Directional Drilling(HDD) in rock ground layers is a common construction problem for many trenchless construction. This kind of construction has various problems different from horizontal directional drilling in soil layer, such as difficult construction, slow construction speed and poor efficiency and so on. High-quality drilling tools can not only help improve these problems, but also reduce the occurrence of drilling accidents, greatly improve construction efficiency, and reduce drilling costs.
HDD Rock Reamers plays an important role in Horizontal Directional Drilling(HDD) in rock ground layers.As the one of the top manufacture of HDD Tooling, ZH HDD Tooling has been committed to constantly research and development of new technology, adhere to the selection of high-quality materials, strict management of the production process to provide customers with reliable HDD Rock Reamers.
ZH Tooling China HDD Rock Reamers can design and manufacture the rock reamers size from 10” to 72” .
ZH Tooling China HDD Rock Reamers chooses TCI cutters or Steel tooth cutters. And the teeth have good wear resistance, longer service life, and improve the drill speed. Intensive palm tip welding and full palm back protection, the cones are divided into back dimension and the diameter is protected by a protective design to effectively enhance the resistance of the Drill Bits. Greatly provide Horizontal Directional Drilling(HDD) efficiency.

1. The ZH HDD Tooling China HDD Rock Reamers has lower-torque Rock Reamers, so that Rock Reamers can be reamed with a smaller rig, by this way can help the construction company save drilling costs, so as to achieve higher economic interests.
2. ZH HDD Tooling China HDD Rock Reamers more reliable in the extreme working conditions. Feedback on site, ZH Tooling China HDD Rock Reamers can bear bigger drilling pressure, pull force in the case of reverse reaming, and thrust force in the case of forward reaming. In HDD construction, different worksite has different requirements for drilling pressure. Most reaming accidents in rock ground layer are caused by excessive pursuit of reaming speed and excessive drilling pressure.
3. The rollers of ZH Tooling China HDD Rock Reamers can be replaced, so that the main structure bodies can be used multiple times. When the rollers of the HDD Rock Reamers damaged by prolonged work, the operator can take off the damaged rollers and welding the new rollers on the main structure bodies. Put back into drilling so that saving engineering costs.
4. ZH HDD Tooling has variety of large-size HDD Rock Reamers to meet the requirements of different HDD construction.
5. ZH HDD Tooling China HDD Rock Reamers choose main structure bodies to support rotate speed from the Drill Rig. The rotate speed refer to the speed at which the drill rod is driven by the drill to drive the reamer to rotate, and the adjustment of the rotate speed is mainly related to the hardness of the rock. It is an important parameter to measure rock drilling. When drilling in hard rock, the speed should be reduced accordingly, generally 10 to 40Rpm. Too low speed will reduce the efficiency of reaming, which is not economical; too high speed will cause abnormal wear of the reamer, and even cause reaming accidents.
