Product Details
The 3M™ PSA cloth disc 348D 3/4" x NH 60 grit aluminum oxide is a heavy-duty sanding disc designed with a high-strength pressure-sensitive adhesive backing for efficient application and clean removal on a backup pad or steel platen. It features a heat-resistant resin bond and cloth backing, making it suitable for high heat and heavy-duty sanding tasks. The disc contains aluminum oxide particles in a closed coat for a fast cut on metal during grinding and dual action sanding. This versatile disc is ideal for deburring, blending, cleaning up, and finishing metal parts and surfaces of various sizes and shapes. The PSA adhesive allows it to be pressed onto a backup pad, which is then attached to a disc sander, random orbital sander, or stationary disc sander. Aluminum oxide abrasive offers fast cut-rate, long life, and self-fracturing for fresh cutting edges, making it more durable than traditional abrasives like garnet. It exhibits hardness, strength, and low heat retention, making it widely used in grinding, sanding, and finishing applications on a variety of materials including ferrous alloys in woodworking and metalworking. Heat-resistant resin serves as a sturdy binding agent for the abrasive, maintaining bond stability under high heat or pressure. Typical applications include blending, deburring, grinding, and orbital sanding on flat areas, metal fabrication, and primary wood and panel processing industries. The product is compliant with industrial standards and designed for professional use. Warranty information is provided with terms applicable to manufacturing defects and product performance.
