Introduction

HDDD hole openers for horizontal drilling

Horizontal reamer, also known as HDDD reamer, is used to expand the pilot hole of horizontal directional drilling (HDDD) - HDDD is used when grooves and excavations are not practical. This drilling technique allows drilling underground in a manipulable trenchless manner.

There are three stages

1. The first stage is to drill a small diameter guide hole.

2. The second stage is to enlarge the hole with a larger diameter tool called HDD reamer.

3. The third step is to insert the casing or other product into the reaming hole.

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.
