The 3M Ceramic & Aluminum Oxide Sanding Belt is a high-performance 80 grit sanding belt, ideal for heavy-duty sanding, grinding, and finishing applications. This belt is 1/4 inch wide and 18 inches long, engineered for efficient material removal and long-lasting durability.
Unlike traditional aluminum oxide sanding belts, this belt features a unique ceramic and aluminum oxide blend, offering faster cutting action and extended belt life. The heavyweight polyester backing allows for high-pressure applications, making it suitable for both wet and dry sanding.
This sanding belt is bi-directional, meaning it can be used in either direction for even wear and optimal performance. The addition of a grinding aid reduces heat buildup, improving performance when working with heat-sensitive materials like stainless steel and titanium.

Product Highlights
Why Choose a 3M 80 Grit Sanding Belt?
Unlike standard aluminum oxide sanding belts, the ceramic and aluminum oxide grain combination in this 3M sanding belt provides:
Faster Cutting & Longer Life – Ceramic abrasives maintain sharpness longer, meaning fewer belt changes and increased productivity.
High Heat Resistance – Grinding aid reduces heat buildup, preventing warping on heat-sensitive materials like stainless steel and titanium.
Heavy-Duty Backing – The YF-weight polyester backing withstands high pressure, making it ideal for aggressive sanding applications.
Wet & Dry Versatility – Can be used dry or with coolants, allowing for greater application flexibility.
What is an 80 Grit Sanding Belt Used For?
An 80 grit sanding belt is classified as a medium-grit abrasive, making it suitable for:
Stock Removal & Material Shaping – Efficiently sands down rough surfaces on metal, wood, and composites.
Deburring & Edge Rounding – Removes sharp edges and burrs from stainless steel, aluminum, and soft metals.
Surface Preparation for Coatings & Welding – Creates a uniform finish before painting, coating, or welding.
Refining Scratch Patterns – Bridges the gap between coarse sanding (50-60 grit) and fine finishing (120-150 grit).
Frequently Asked Questions
What materials can this 80 grit sanding belt be used on?
This 3M 80 grit sanding belt is designed for metals, wood, and composites, with optimal performance on stainless steel, aluminum, copper, titanium, and high-nickel alloys.
Can this sanding belt be used in both directions?
Yes, this belt has a bi-directional butt joint, meaning it can be run in either direction for even wear and longer belt life.
How does ceramic aluminum oxide compare to regular aluminum oxide?
Ceramic aluminum oxide lasts longer than standard aluminum oxide due to its self-sharpening properties.
It cuts faster, requires less pressure, and reduces heat buildup, making it better for tough materials like hardened steel and titanium.
Can this sanding belt be used for wet sanding?
Yes, the polyester backing allows for both wet and dry use, giving you more versatility in different sanding applications.
