The Compact Fluted HD Backreamer is built with heavy-duty features like integrated swivel options and replaceable hardened-steel nozzles for greater fluid distribution and flow flexibility. Its heavy-cast body and tapered base compact soils to provide smooth pushback capability and easier product installation. Featuring an improved cutting structure, hardened carbide teeth and spiral-fluted design, the Compact Fluted HD delivers the best performance in hard, compacted ground conditions, including chuck rock and cobble. Conditions vary. Your results don’t.
