The 16" Fluted HDD Reamer with built-in 25T swivel is engineered for large-diameter horizontal directional drilling applications in soft to medium soil conditions. Rated for 25T 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 evacuation on demanding trenchless construction projects including pipeline installations, municipal utility bores, conduit runs, water and sewer line installations, and infrastructure projects requiring large bore diameters in soft to medium ground.

The fluted reamer design promotes superior drilling fluid circulation throughout the annular space, ensuring effective soil displacement and maintaining a clean, stable bore wall during the reaming pass and pullback. The integrated 25T swivel eliminates pipe rotation during product pipe installation, protecting both the pipe and drill string from torsional stress and ensuring a smooth, controlled pullback on extended or complex bore paths in soft to medium ground conditions.

The 16" diameter is well suited for product pipes ranging from 10" to 12" 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 mid-to-large frame drill rigs including Vermeer D80x100, Ditch Witch JT60, Toro TDD8020, American Augers DD-90, and other machines rated for the required pull force and fluid flow on large-diameter bores in soft to medium soil.
