Product Details
The 3M™ PSA Cloth Disc 348D is a 30" diameter sanding disc with 80 grit aluminum oxide abrasive, designed for heavy-duty sanding and grinding applications. It features a high-strength pressure-sensitive adhesive (PSA) backing that securely adheres to a backup pad or steel platen for efficient application and clean removal. The disc is constructed with a heat-resistant resin bond and durable cloth backing, making it suitable for high heat and heavy use. The closed coat aluminum oxide abrasive provides a fast cut rate and long life, self-fracturing to expose fresh cutting edges during use. This abrasive is effective on metal surfaces, including ferrous alloys, and is widely used in metal fabrication and primary wood and panel processing industries. The sanding disc works well for deburring, blending, cleaning, finishing, and grinding flat or contoured metal parts on random orbital sanders, disc sanders, and dual action sanders, using a backup pad sold separately. The heat-resistant resin bond maintains stability under high heat and pressure while adhering the abrasive to the cloth backing. The product meets industrial standards for durability and performance and carries warranty terms consistent with 3M’s product guarantees.
