The business of horizontal directional drilling is inherently risky. When the job involves installing large-scale utilities, risk scales up quickly. That’s why so many contractors rely on StraightLine HDD.

This custom reamer solution was built for a contractor who required aggressive push/pull capability to execute a series of three back-reams. In addition, three Barrel reamers were specified to stabilize the hole. Following a brief consultation, a plan was put into motion. To handle the volume produced by the 400+ GPM mud pump and to maximize spoils removal, the Wing reamer design incorporated generous perimeter flow and forward- facing fluid distribution. The companion Barrel reamers were sized precisely to accommodate the Wing diameters.
A similar custom reamer order was featured in a 2015 Canadian Underground Infrastructure article.
