Product Details
The 3M™ PSA Cloth Disc 348D 8" x NH P100 grit aluminum oxide sanding disc is a heavy-duty abrasive tool designed for high heat and demanding sanding applications. It features a high-strength pressure sensitive adhesive (PSA) backing that securely adheres to a backup pad or steel platen, allowing for efficient application and clean removal. The disc incorporates a heat-resistant resin bond and a durable cloth backing, ensuring stability under high temperatures and pressure. The abrasive surface consists of aluminum oxide particles arranged in a closed coat, providing a fast cut suitable for grinding and dual action sanding on metal surfaces. This disc is effective for deburring, blending, cleaning, and finishing metal parts of various sizes and shapes. The aluminum oxide mineral is known for its toughness, fast cut rate, long life, and self-fracturing capability to expose fresh cutting edges, making it preferable to traditional abrasives like garnet. The disc is designed to be pressed onto a separately sold backup pad, which can then be attached to disc sanders, random orbital sanders, or stationary disc sanders. It is suitable for use on ferrous alloys, and its applications include blending, deburring, grinding, and orbital sanding in metal fabrication, primary wood, and panel processing industries. Warranty and certification details were not specified in the original description.
