The 14" 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. Compatible with any type thread connections and rated for 25T pull force, this fly cutter reamer delivers aggressive cutting action and reliable bore enlargement on demanding trenchless projects including pipeline installations, municipal utility bores, water and sewer line installations, and commercial HDD applications requiring higher pull force capacity in challenging ground.

The fly cutter design utilizes an aggressive blade configuration to break through medium to hard soil, gravel, cobble, and soft rock, while maintaining effective drilling fluid circulation to promote cuttings evacuation and bore wall stability during 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 or more demanding bore paths.

The 14" diameter is well suited for product pipes ranging from 8" to 10" in outer diameter, following the standard HDD industry practice of selecting a reamer at approximately 1.5x the pipe OD. Compatible with any type of connections, this reamer fits mid-to-large frame HDD drill rigs including Vermeer D60x90, Ditch Witch JT40, Toro TDD6020, American Augers DD-65, and other machines capable of delivering the required pull force for mid-size bores in medium to hard ground.
