Directional Drilling HDD Backreamers

From sand to granite, No Dig Equipment offers a wide range of back reamers for directional drilling, so you can maximize productivity in the hole no matter what the ground conditions are.

We build Long Life Backreamers

Directional drilling backreamers must combine hardness for long life and toughness for long term durability so that the tool does not fail under the normal back reaming forces.

A superior finish to the bored hole

Reaming should only remove small amounts of material in a progressive manner, this ensures a long life for the reamer and a superior finish to the bored hole.

No Dig Equipment provides a wide range of directional drilling HDD back reamers to suit all your trenchless jobs.

Rear Coupling


No Dig Equipment manufacture connector subs / adaptors compatible with most common Vermeer and Ditch Witch HDD Drill Rigs.  Our adaptors are specifically designed to match our backreamers.  They provide an easy solution to

utilise reamers between different models of machines by simply changing out the front sub / adaptor.

This also provides a very cost effective solution for repairing your backreamer, as it is usually the front thread that wears out prematurely.  With the use of a cheap replaceable adaptor, you can be backreaming fast.

For a complete range of our adaptors please have a look at the the table below. Other connector subs / adaptors and crossover subs are available on request.
