Product Details
3M™ PSA Cloth Disc 348D is a heavy-duty sanding disc designed with a high-strength pressure sensitive adhesive backing that adheres securely to a backup pad or steel platen, enabling efficient application and clean removal. This sanding disc features a heat-resistant resin bond and durable cloth backing, making it suitable for high heat and heavy-duty sanding applications. The aluminum oxide particles in a closed coat provide a fast cut for grinding and dual action (D/A) sanding on metal surfaces. It serves as a versatile tool for deburring, blending, cleaning, and finishing metal parts of various sizes and shapes. The PSA (pressure-sensitive adhesive) disc is pressed onto a backup pad, which can be attached to disc sanders, random orbital sanders, or stationary disc sanders, with the backup pad sold separately. The choice of aluminum oxide abrasive is a favored option among industrial professionals due to its fast cut-rate and long life, as this tough mineral self-fractures to expose fresh cutting edges during use, in contrast to traditional abrasives that wear down quickly. This abrasive is effective in a range of materials for both woodworking and metalworking applications, including ferrous alloys. The heat-resistant resin serves as a sturdy binding agent that ensures the stability of the bond even under conditions of high heat or pressure. Key applications include blending, deburring, flat areas, grinding, orbital sanding, random orbital sanding, and metal fabrication, with industries served including metal fabrication, primary wood, and panel processing.
