American Augers

From 18 inches to 34 inches, the Hole Opener by American Augers is the much needed HDD jobsite tool when conducting reaming or pre-reaming operation through intrusive hard soils or rock formations.

Melfred Borzall

The Ogre Reamer is one tough reamer with more cutters than any other reamer in its class. Available in cut sizes from 12 to 36 inches, each cutter takes off only ¼ inch more soil than previous stage resulting in a smooth, efficient cutting action. Slow taper and deep spiraled fluting combine to give the Ogre maximum mixing and pumping. Angled fluid jets shoot water opposite the reamer rotation. Hardfacing is on all wear areas and there are curved backup blades for easier pushbacks. 800.833.1252,

Railhead Underground Products
Building on the success of the 8-, 12- and 16-inch EXTReam, Railhead now offers the reamer in 6 and 10 inches. These reamers are built with an API pin and box with a removable pulling eye at the back of the reamer. This allows the user to quickly hook up many configurations. The EXTReam is delivered from the factory with most of the side and rear water ports plugged which forces most of the flow out the front to properly mix the cuttings. Railhead supplies a variety of different size nozzles and plugs that can be used to reconfigure the water ports based upon the volume of mud being pumped and the conditions encountered during the pilot bore. 817.594.6663,

Sharewell HDD Services
Sharewell’s heavy-duty LTX series of Lo-Torque Hole Opener is ideal for pipeline projects. The field replaceable cutters are available in IADC TCI type 5, 7 or 8 and in mill tooth style. Each body can open four different hole sizes, and the larger cutters have big sealed bearings for longer downhole life. With only the cutters contacting the formation, less torque is required to operate the tool. 281.288.2560,
