3M Click To Copy Sanding Disc by 3M

The 3M PSA Cloth Disc 348D boasts a heat-resistant resin bond and cloth backing, making it ideal for high heat and heavy-duty sanding tasks. Aluminum oxide particles in a closed coat deliver swift grinding and dual-action sanding on metal. This versatile disc offers a quick, efficient way to deburr, blend, clean up, and finish metal parts and surfaces of various sizes and shapes. The PSA (pressure-sensitive adhesive) disc attaches to a backup pad on disc sanders, random orbital sanders, or stationary disc sanders. The 348D features aluminum oxide abrasive, favored by professionals for its fast cut-rate and longevity. This tough, durable mineral self-fractures to expose fresh cutting edges, unlike traditional abrasives like garnet. Aluminum oxide's fast cut-rate, hardness, strength, and low heat retention make it suitable for various materials in woodworking and metalworking, including ferrous alloys. The heat-resistant resin binding agent ensures the abrasive stays adhered to the backing, even under high heat or pressure.
