3M 068060-66994 732U 320+ C-WT 5″ X NH DIE 500LG Abrasive Discs

This is a high-quality 3M abrasive disc, specifically designed for fine sanding and finishing work. It uses a P320+ grit aluminum oxide mineral on a durable C-weight backing. The “NH” (Non-Hole) design ensures full surface contact, making it ideal for processes where dust extraction isn’t critical or when used on manual sanding blocks, delivering consistent, reliable results for smooth finishes.

• The durable C-weight paper backing resists tearing and creasing during use, meaning you won’t have to stop frequently to replace damaged discs.
• The 320+ grit rating provides an extremely fine scratch pattern, which is crucial for preparing surfaces for clear coats, lacquers, or other final finishes.
• These discs come in a die-cut format, ensuring uniformity and quick removal from the liner, which speeds up your workflow, especially in high-volume applications.

Who this is best for

This product is best suited for auto body shops, woodworking professionals, and metal fabricators who need a very fine, non-aggressive sanding action for prepping surfaces, blending finishes, or completing the final steps before painting or sealing.
