Abstract (en)
A rotatable tool (1) for holding an abrasive sheet so as to clean pipes internally, comprising a separate clamping (4) piece, such that an abrasive sheet may be attached to the tool (1) by clamping it in a slit (6) between the clamping (4) piece and the body (2) of the tool (1). An end cap (5) is attached to the body in a longitudinally adjustable manner, so as to at least partially house a longitudinal end of the clamp piece, such that a longitudinal movement of the end cap (5) towards the body (2) pushes the clamp piece (4) laterally towards the body (2), thereby securing the abrasive sheet in place. Correspondingly, the slit (6) can be then widened for removal of the abrasive sheet by moving the when the end cap (5) longitudinally away from the body (2). A corresponding tool assembly is also concerned.
