Abstract
An abrasive-means holding device for holding an abrasive means includes a holding body that is operable to rotate about a central axis. The holding body has a first side, a second side facing away from the first side, and a vacuuming opening that extends therethrough from the first side to the second side. The holding body also has a group of aspiration cavities that are arranged on the first side and that are fluidically connected to each other by at least one through-hole that connects the aspiration cavities. At least one aspiration cavity forms a vacuuming cavity that is directly fluidically connected to the vacuuming opening and that is configured to vacuum-off dust immediately out of an adjacent aspiration cavity and mediately out of a more distantly adjacent aspiration cavity. The aspiration cavities of the group are arranged in relation to each other along a linear course.
