The 8" Fluted HDD Reamer with built-in 12T swivel is a reliable and widely used tooling solution for horizontal directional drilling contractors working in soft to medium soil conditions. Rated for 12T pull force and compatible with all major HDD drill string thread connections via the included universal thread adapter, this fluted directional drilling reamer delivers consistent bore enlargement and efficient cuttings removal on residential and light commercial trenchless construction projects including utility installations, conduit runs, fiber optic cable placement, gas and water service connections, and service lateral installations requiring compact bore diameters.
The fluted reamer design ensures steady drilling fluid circulation throughout the annular space, promoting effective soil displacement and maintaining a clean, stable bore wall during the reaming pass and pullback. The integrated 12T swivel minimizes pipe rotation during product pipe installation, reducing torsional stress on both the drill string and the pulled pipe and contributing to a smoother, more efficient pullback on standard residential and light commercial bore lengths in soft to medium ground.
The 8" diameter is ideally suited for product pipes ranging from 3" to 5" in outer diameter, following the standard HDD industry practice of selecting a reamer at approximately 1.5x the pipe OD. The included universal thread adapter ensures full compatibility with all major HDD drill manufacturers including Vermeer, Ditch Witch, Toro, and American Augers, making this reamer a versatile tooling solution for compact and mid-size drill rigs including Vermeer D16x20, Vermeer D20x22, Vermeer D24x40, Ditch Witch JT20, Ditch Witch JT25, Toro TDD2024, and other machines commonly deployed on residential utility installations, service lateral replacements, and light commercial trenchless drilling projects in soft to medium soil.
