Rock Reamer
The Rock Reamer is the most versatile, cost effective hole opener for HDD. The unique design minimizes on-site inventory, lowering cost. The Rock Reamer cuts downtime as easily as it cuts rock. No more downtime waiting on new tools/cutters when the need to push ream occurs. It pushes or pulls with the same body and cutters, and one body opens to six sizes.
Stronger than other hole openers. Increased on-bottom rotating time, minimizes cutter cost and trip time. Cutters and arms are easily changed in the field without torches and welders.
