ABSTRACT:
An abrader, such as a motorized disk sander, is provided with an annular chamber which surrounds the disk and which has a plurality of small openings proximate the work surface. A depending skirt on the chamber confines the abraded material. The mounting of the chamber provides for limited axial and rocking movement of the chamber with respect to the abrader to facilitate catching abraded material from curved work surfaces and in instances where the abrader is applied at an acute angle to the work surface. The motility also facilitates installation and removal of the attachment and of abrasive sheets to and from the disk of the abrader. By preference, the mounting provides for unlimited rotation of the abrading machine body with respect to the chamber. In one embodiment, the chamber is provided with an enlarged "slug catcher" opening for capturing larger pieces abraded from the work surface.
