3M 348D Series Abrasive Disc, 12 in Dia, P80 Grit, PSA, Brown

The 3M PSA cloth disc 348D is a robust sanding disc, equipped with a strong pressure-sensitive adhesive backing that securely adheres to backup pads or steel platens, ensuring efficient application and easy removal. This disc features a heat-resistant resin bond and durable cloth backing, making it ideal for high-heat and heavy-duty sanding tasks. Aluminum oxide particles in a closed coat provide swift cutting for grinding and dual-action sanding on metal. This versatile disc offers a fast and efficient method for deburring, blending, cleaning up, and finishing metal parts and surfaces of various sizes and shapes. Aluminum oxide abrasive, favored by industrial professionals for its fast cut rate and longevity, is used here. It's a tough, durable abrasive that self-fractures to expose fresh cutting edges during use, unlike traditional abrasives like garnet that wear down quickly. Due to its fast cut rate, hardness, strength, and low heat retention, aluminum oxide is widely used in grinding, sanding, and finishing applications, suitable for a variety of materials in both woodworking and metalworking, including ferrous alloys. The heat-resistant resin binding agent ensures the abrasive stays adhered to the backing, maintaining bond stability even under high heat or pressure.
