ABSTRACT:
A pad sander skirt which flares out over the periphery of the sanding pad and which is coupled to a lower housing so that it swivels about the body of the sander. The skirt and lower housing can be selectively swivelled in a rotational manner to a position desired by the user. A further sander improvement disclosed relates to the protection of a user's hand. Palm-grip random orbit sanders are sometimes configured so that the sanding pad may begin spinning at high speed when the sander is lifted off of the work. To this end, the present application discloses a protective skirt which flares out over the periphery of the pad in a palm-grip random orbit sander. Also disclosed is an improved dust collection system comprising a filter housing formed of a rigid porous material for entrapping dust.
