Sometimes, for questions of space limitation, access, sizes, the use of brushing machine results uncomfortable or not possible.
With drilling shafts is possible to clean systems like VMC or ships, trains ducts.
The drilling shaft is enstablished from special plastic tube, where inside spins a strong steel cable.
On the drilling shaft is possible to use brushes up to 400 mm, on the other side of the brush is attached to a driller (atleast 18V if battery). The drilling shafts are available in different length from 3 to 10 meters.
On demand it’s possible to reinforce the drilling shafts with a fiber glass cable that are set to the drilling shafts to give better rigidity to the torque.
It’s possible to insert on the brush side an elastic joint (accessory with spring picture) to allow less resistance in presence of ducts with angles really tight.
