* "naked" shaft allow you to finalize the customization : Tell us the size of the pilot hole and we will fit the right Front Stabilizer. Tell us what is your Horizontal Directional Drill and we will fit the right Front Adapter Sub as well as the rear-end, be a single pulling eye or a Swivel. Here are some samples of Rock Back Reamers we have manufacture for our clients.  No Dig Equipment carries some stock hole openers in house, however most of these reamers need to be made to order.  So if you require a specific hole opener for your next job, please tell us the size of the pipe you need to install and the rock formation you are drilling in, and we will design the best Rock Reamer for your needs.

Reamers with Built-in Stabilizers


Stay straight in the hole with our built-in stabiliser Rock Reamer / Hole Opener. These units are custom build on request and would generally be used where it is required to open up a hole in a gradual manner.  If the conditions are right these reamers are very cost effective as they do not require an expensive set of stabilizers or barrel reamers to be towed in tandem.

All our hole openers and rock reamers can be supplied with a range of cutters to deal with soft rock like limestone or sandstone, right up to hard formation bits capable of drilling in Granite and Basalt.  Correct cutter selection allows higher productivity and tool life.


MadeToOrderOur rock reamer can be custom build with 3, 4, 5 or more rock bits depend on your pullback power and the diameter of the pipe.  A wide selection of cutters are available to allow drilling in conditions from soft rock right through to the hardest granite.  Our Hole openers are generally fitted with API threads, however in the smaller sizes we can adapt our standard connection sub range to suit Vermeer and Ditch Witch machines.
