The 12" Fly Cutter HDD Reamer with built-in 25T swivel is engineered for horizontal directional drilling applications in medium to hard soil, cobble, and soft rock conditions where standard fluted reamers are no longer sufficient. Rated for 25T pull force and compatible with all major HDD drill string thread connections via the included universal thread adapter, this fly cutter directional drilling reamer delivers aggressive cutting action and reliable bore enlargement on demanding trenchless construction projects including pipeline installations, utility bores, conduit runs, water and sewer line installations, and commercial HDD applications requiring superior cutting performance in challenging ground.

The fly cutter blade configuration breaks through medium to hard soil, gravel, cobble, and soft rock formations while maintaining effective drilling fluid circulation throughout the annular space, promoting consistent cuttings evacuation and bore wall stability 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 longer and more demanding bore paths in difficult ground conditions.

The 12" diameter is well 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 and reliable tooling solution for mid-size trenchless drilling projects across a wide range of drill rig configurations.
