Flycutter backreamer

A high-performance backreamer featuring tungsten-carbide claws, a versatile nozzle system, and a stabilizing ring to maximize productivity and deliver smooth, controlled reaming operations.

Mud-mixing reamer

Flycutter reamer range

Designed for demanding HDD projects, the Flycutter reamer range delivers reliable performance, efficient cuttings removal, and exceptional durability. Tungsten-carbide claws combined with a versatile nozzle system ensure effective mixing and evacuation of cuttings, while the stabilizing ring helps maintain a smooth and consistent bore path. Available in box/box or pin configurations, with welded swivel, pull tab, or virtually any thread connection. Built to perform in challenging ground conditions and engineered to keep your operation moving, job after job.

Choose the Flycutter for mixed soils where the reamer has to mix the cuttings into the drilling fluid and carry them out. The stabilizing ring keeps the reamer centred in the bore, for a smoother pull and a consistent bore path.
