HDD hole opener for horizontal drilling
Horizontal Hole Openers, also known as HDD Reamers, are used to enlarge the pilot hole in Horizontal Directional Drilling(HDD) - HDD is used when trenching and excavating is not practical.This drilling technology allows for a steerable trenchless way to drill underground.


The main structure features

Reamer with interchangeable tool was developed for large diameter HDD projects where extending downhole life is critical. Larger bearings and tools significantly extend downhole life compared to smaller, conventional types of tools.

Replaceable milling sets are available in TCI and grinding teeth to accommodate a variety of rock formations. All bits have 3-6 cutters and can be drilled in 4 different sizes.

All tool bearings are metal sealed. Tool locks are used to prevent cutting tools from falling off.

It can provide 400-2000mm hole opener.
