A sanding wheel that may be used, e.g., to finish a wood deck, includes one or more risers. Each riser includes an angled face and a cross member, and the angled face and cross member define a slot therebetween. The retaining or fastening clip includes a retaining spring, and the fastening clip is received on the angled face of the riser with the retaining spring extending into the slot. The blade has an abrasive on a first end and an aperture at a second end, the aperture being defined by a shoulder about the aperture. The second end of the blade extends into the slot with the retaining spring of the fastening clip engaging the shoulder. The slot and the retaining spring are configured to mechanically lock the blade to the riser and the base.

A polishing brush (1) includes a brush-shaped grindstone (12) holding grinding element bundles (11) of wire-shaped grinding elements (27) in an annular shape and a grinding element displacement-restricting member (13) for restricting displacement of the grinding element bundles (11) outward. The brush-shaped grindstone (12) has a grinding element holder (15) holding the base end portions (upper end portions) of the grinding element bundles (11). The grinding element displacement-restricting member (13) has an annular part (33) surrounding the wire-shaped grinding elements (27) from the outer peripheral side at a position between the tip ends of the wire-shaped grinding elements (27) and the grinding element holder (15) in the direction of the axis of center of rotation (L) and at a distance away from the tip ends of the wire-shaped grinding elements (27) and the grinding element holder (15). Since the portions on the side closer to the grinding element holder (15) of the grinding element bundles (11) held in the grinding element holder (15) are exposed outward, cutting fluid or air supplied from the outer peripheral side of the polishing brush (1) easily reaches the polished portion of a workpiece.

An abrasive flap disc having improved properties with respect to production and grinding behavior combines an abrasive grit having a special grit mixture having 25% to 75% (high-performance ceramic) zirconium dioxide and of 25% to 75% aluminum oxide and a number of abrasive lamellae per abrasive flap disc in the range between 30 and 46.

A low pressure, low speed concrete polishing apparatus and method of cleaning and polishing a floor a polishing pad and interchangeable polymer strips. The interchangeable polymer strips are slideably received within the housing of the pad. The polymer strips have an abrasive material embedded therein which collectively work to polish the floor while cleaning the floor during normal speed floor cleaning conditions.
