Adhesive-Back Sanding Discs for Masonry, Ceramics, and Composites

These discs have a long-lasting diamond abrasive. Press onto a compatible sanding tool or backup pad (sold separately); peel off to remove. Also known as PSA discs. To maintain strong adhesion, clean the pad surface with mild alcohol before applying. Do not use aggressive cleaning solvents such as MEK or acetone, which can damage the adhesive.

Flap Sanding Discs for Masonry, Ceramics, and Composites

Overlapping abrasive flaps bonded to a backing plate provide consistent material removal and even finishes. As the top layer of abrasive wears away, a new layer is exposed. Attach to your tool’s arbor.

Grinding Wheels for Angle Grinders—Use on Nonmetals

Silicon carbide cuts through concrete and stone without generating much heat. Wheels are also known as Type 27 wheels, raised-hub wheels, and grinding discs.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Heavy-Removal Grinding Wheels for Angle Grinders—Use on Nonmetals

Wheels have a large surface area and a thick layer of rough abrasive for heavy material removal on concrete and stone. They are also known as Type 11 wheels, flared-cup wheels, snagging wheels, and cup stones.

Wheels are silicon carbide, which won't generate much heat. The full backing provides additional support.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
