Product Details
The 3M™ PSA cloth disc 348D is an 18" diameter, 36 grit aluminum oxide heavy-duty sanding disc featuring a high-strength pressure sensitive adhesive backing designed to adhere to a backup pad or steel platen for efficient application and clean removal. It incorporates a heat-resistant resin bond and cloth backing, making it suitable for high heat and heavy-duty sanding applications. The aluminum oxide particles are arranged in a closed coat, providing a fast cut ideal for grinding and dual action (D/A) sanding on metal. This disc is versatile 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 attaches to a disc sander, random orbital sander, or stationary disc sander. Aluminum oxide is chosen for its fast cut-rate, toughness, durability, and self-fracturing property that exposes fresh cutting edges, outperforming traditional abrasives such as garnet. It is suitable for a wide variety of materials in woodworking and metalworking, including ferrous alloys. The heat-resistant resin securely binds the abrasive to the cloth backing, maintaining bond stability even under conditions of high heat or pressure. Typical applications include blending, deburring, working on flat areas, grinding, orbital sanding, and random orbital sanding. The disc is commonly used across metal fabrication and primary wood and panel processing industries. Warranty terms are provided but not specified in the description.
