• Flexible cloth backing provides ideal conformability for blending and finishing contours and complex parts
• Open coat construction helps evacuate sanding dust from the belt for a more aggressive cut and longer abrasive life, which means greater productivity
• Resin bonded belt maximizes abrasive life
• Suitable for dry metalworking applications
• Tough aluminum oxide abrasive cuts fast and performs well on most metals

3M Cloth Belt 302D is an aluminum oxide belt with open coat construction and a flexible J-weight backing that conforms well for sanding contours and complex parts. It is best-suited for light grinding, finishing, deburring and setting the grain on carbon steel and stainless steel, as well as soft metals like aluminum, brass, bronze and copper.

Built with Added Flexibility
3M Cloth Belt 302D has an open coat construction that helps channel sanding swarf and dust away from the belt and workpiece for better visibility and belt performance. The abrasive and backing are resin bonded to keep the belt running until the abrasive is completely worn. We recommend you select this belt for operations that require added flexibility.

Made with Durable, Fast-Cutting Aluminum Oxide
Aluminum oxide mineral is a popular choice among industrial professionals because of its cut-rate, durability, and long life. It can be used on a wide variety of materials in metalworking, including ferrous alloys, and is the most commonly used industrial abrasive. The abrasive particles are adhered to the cloth backing with resin, creating a strong bond that withstands high heat and pressure.

The Benefits of Open-Coat Construction
Loading occurs when swarf or paint dust clogs the surface of the belt and the abrasive points, rendering the belt ineffective. Open coat construction means the abrasive grains are spaced slightly apart so that dust and debris have an outlet rather than loading the abrasive. These attributes make 3M Cloth Belt 302D great for use on soft metals like aluminum, brass, bronze and copper. Additionally, the open coat construction provides a more aggressive cut than a comparable closed coat abrasive of the same grade.

Trusted 3M Cloth Belt

The 3M Cloth Belt 302D offers reliable performance with its aluminum oxide abrasive. This belt is designed specifically for backstand grinders, file belt tools, and benchtop motors, ensuring compatibility with common metalworking equipment.

Its J-weight flexible cloth backing provides excellent conformability, making it ideal for blending and finishing contours or complex parts. The belt’s design supports smooth operation and consistent results.

Precise Size And Format

This belt measures 3 inches by 132 inches, a size that fits many standard sanding and grinding tools. The Film-lok full-flex format enhances durability and flexibility, allowing it to handle detailed work without cracking or breaking.

With these dimensions and format, the belt suits a variety of metalworking tasks, including light grinding and deburring, especially on carbon steel and stainless steel surfaces.

Open Coat Construction Benefits

The open coat design helps evacuate sanding dust from the belt, preventing clogging and maintaining an aggressive cut. This feature extends the abrasive life and improves productivity during use.

Because dust and debris have an outlet, the belt performs well on soft metals like aluminum, brass, bronze, and copper, reducing loading and keeping the sanding surface effective longer.

Durable Aluminum Oxide Abrasive

The tough aluminum oxide abrasive cuts fast and lasts long, making it a popular choice for metalworking professionals. It works well on most metals, including ferrous alloys, providing consistent results.

Resin bonding secures the abrasive to the cloth backing, helping the belt withstand high heat and pressure during demanding tasks, which maximizes abrasive life and efficiency.

Convenient Pack Size Case

This product comes in a case of 50 belts, with each pack containing 25 belts. This bulk packaging supports high-volume operations and reduces the need for frequent reordering.

Having a large quantity on hand is ideal for workshops and industrial settings where consistent supply and quick replacement are essential to maintain workflow.
