Shredder backreamer
Like the Flycutter but without the stabilizing ring – open wings for maximum mud flow and mixing where circulation matters most.
Shredder reamer range
The Shredder delivers the same rugged performance as the Flycutter, but drops the stabilizing ring for even greater mud-mixing capacity. The open space between the wings improves mud flow and mixing – ideal where efficient circulation is critical. Tungsten-carbide claws and a versatile nozzle system give high output and long life in demanding ground.
Choose the Shredder over the Flycutter in cohesive soils where the cuttings must be mixed thoroughly and the flow past the reamer matters more than stabilisation. The open wings leave the largest possible passage for the drilling fluid.
