The 10" Fluted HDD Reamer with built-in 20T swivel is engineered for horizontal directional drilling applications requiring increased pull force capacity in soft to medium soil conditions. Rated for 20T pull force and compatible with all major HDD drill string thread connections via the included universal thread adapter, this fluted directional drilling reamer delivers reliable bore enlargement and efficient cuttings evacuation on mid-size trenchless construction projects including utility installations, conduit runs, pipeline bores, water and sewer line installations, and commercial HDD applications where greater pulling capacity is required beyond standard light-frame machine ratings.
The fluted reamer design ensures consistent drilling fluid circulation throughout the annular space, promoting effective soil displacement and maintaining a stable bore wall during the reaming pass and pullback. The integrated 20T swivel eliminates unwanted pipe rotation during product pipe installation, reducing torsional stress on both the drill string and the pulled pipe and ensuring a smooth, controlled pullback on longer bore paths or in soil conditions that demand higher pull force ratings.
The 10" diameter is well suited for product pipes ranging from 6" to 7" 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-frame drill rigs including Vermeer D33x44, Vermeer D40x55, Ditch Witch JT30, Ditch Witch JT40, Toro TDD4020, and other machines capable of delivering the required pull force and fluid flow rates for mid-size bore applications requiring higher torque and pulling capacity.
