The 12" Fluted HDD Reamer with built-in 12T swivel is a versatile and reliable 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 a wide range of residential and light commercial trenchless construction projects including utility installations, conduit runs, fiber optic cable placement, gas and water line bores, and service lateral installations.
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 controlled pullback on standard bore lengths in soft to medium ground conditions.
The 12" diameter is ideally suited for product pipes ranging from 6" to 8" 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 small-to-mid frame drill rigs including Vermeer D24x40, Vermeer D33x44, Ditch Witch JT25, Ditch Witch JT30, Toro TDD3020, and other machines operating in the light-to-medium pull force range on residential and light commercial trenchless drilling projects.
