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 use on 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 and complex parts. This model balances durability and flexibility for precise results.

Precise P240 J-weight Grade

This belt features a P240 grade, which is perfect for light grinding, finishing, and deburring tasks. The J-weight backing supports added flexibility, allowing the belt to conform well to detailed surfaces and complex shapes.

Such a grade is well-suited for setting the grain on carbon steel, stainless steel, and soft metals like aluminum, brass, bronze, and copper, making it versatile for various metalworking needs.

Optimal 3 Inch Width

Measuring 3 inches wide by 132 inches long, this belt fits standard sanding tools and provides ample surface area for efficient material removal. The size supports both precision and coverage during sanding operations.

The length of 132 inches allows for extended use before replacement, reducing downtime. This dimension works well with the belt’s flexible backing and open coat design for consistent performance.

Film-lok Full-flex Technology

The Film-lok system enhances the belt’s durability by securely bonding the abrasive to the backing. This technology ensures the belt runs smoothly until the abrasive is fully worn, maximizing its lifespan.

Full-flex backing adds to the belt’s ability to conform to contours without cracking or breaking. This combination supports aggressive cutting and finishing on complex parts with ease.

Convenient 25 Pack Case

Sold in a case of 50 belts, each pack contains 25 belts, providing a steady supply for ongoing projects. This bulk packaging is ideal for workshops and professionals who require consistent access to quality abrasives.

Having multiple belts on hand reduces interruptions and ensures you can maintain productivity. The pack size also offers cost efficiency for frequent users of the 3M Cloth Belt 302D.
