3M Sanding Disc Aluminum Oxide

3M Sanding Discs with aluminum oxide abrasive are made for sanding, shaping, and surface preparation. They can be used on automotive, marine, RV, and powersports surfaces. Aluminum oxide is a tough, general-purpose mineral. It is widely used for sanding paint, primer, body filler, and bare metal. These abrasive discs are also called sandpaper discs or DA sanding discs.

Key Features:

• Aluminum oxide abrasive: Cuts consistently and lasts a long time on a range of materials.
• Multiple grit options: Coarse grits remove material quickly. Fine grits give a smoother finish before paint or polish.
• Disc format: Fits compatible random orbital and dual-action sanders, so it is easy to use.
• 3M quality: 3M is a long-established maker of abrasives and surface-finishing products. Its abrasives are used in professional body shops and in DIY work.

Choose the grit that suits the job, from heavy stock removal to final finish sanding. These discs help you get a clean, even surface for refinishing and restoration projects.
