Abstract

A power tool including a shroud for restricting the path of debris generated by a rotatable cutting disc and defining a shroud outlet opening through which the debris can be sucked by a vacuum device. The debris enters a sub-volume along a first axis and exits the sub-volume along a second axis in a different plane. A conduit having a curved wall defines the sub-volume such that debris travelling therethough undergoes a change in direction and exits the sub-volume along a direction substantially parallel with the second axis.
