Used to enlarge holes in compressible soil, these high quality back-reamers are self-feeding and produce clean, compacted holes.
ROTO-BORE® Reamers are machined from solid chrome-moly steel bar stock on state-of-the-art CNC lathes and machining centers. All reamers are heat-treated to an average tensile strength of 153,000 psi for optimum strength and toughness.
