Product Details
3M™ PSA cloth disc 348D 8" x NH 50 grit aluminum oxide is a heavy-duty sanding disc designed for high heat and heavy duty sanding applications. It features a high-strength pressure sensitive adhesive backing that adheres to a backup pad or steel platen for efficient application and clean removal. The disc includes a heat-resistant resin bond and a cloth backing, with aluminum oxide particles in a closed coat that provide a fast cut suitable for grinding and dual action sanding on metal. This versatile disc is ideal for deburring, blending, cleaning up, and finishing metal parts and surfaces of various sizes and shapes. The PSA disc is pressed onto a backup pad (sold separately) which can be attached to a disc sander, random orbital sander, or stationary disc sander. Aluminum oxide abrasive offers fast cut-rate, long life, hardness, strength, and low heat retention, making it suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys. The heat-resistant resin bond maintains abrasive attachment and bond stability under high heat or pressure. Typical applications include blending, deburring, flat areas, grinding, orbital sanding, and random orbital sanding, with primary use in metal fabrication and primary wood and panel processing industries.
