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 is designed for reliable performance on backstand grinders and benchtop motors. This exact model ensures consistent results with its P100 J-weight grade, offering the right balance of strength and flexibility.

Its flexible cloth backing conforms well to contours, making it ideal for blending and finishing complex parts. The belt’s design supports various metalworking tasks, enhancing productivity with every use.

Precise Size And Format

This belt measures 2 inches by 132 inches, providing ample surface area for extended sanding sessions. The Film-lok format helps maintain belt integrity and ease of use during demanding jobs.

With a pack count of 25 per case and a total of 50 belts, this product suits both small shops and larger operations needing consistent supply. The size and format make it versatile for many grinding tools.

Flexible J-weight Backing

The J-weight backing offers added flexibility, allowing the belt to conform to intricate shapes and contours. This feature is crucial for finishing and blending on complex parts without damaging the surface.

Its full-flex design supports smooth operation on file belt tools, ensuring the belt adapts well to different angles and curves. This flexibility reduces the risk of uneven sanding or gouging.

Open Coat Construction Benefits

The open coat construction helps evacuate sanding dust, preventing clogging and maintaining aggressive cutting action. This design extends the abrasive life and improves overall productivity.

It’s especially effective on soft metals like aluminum, brass, and copper, where dust buildup can hinder performance. The open coat also enhances visibility during sanding, making it easier to control the process.

Durable Aluminum Oxide Abrasive

Featuring tough aluminum oxide abrasive, this belt cuts fast and performs well on most metals. The resin bond keeps the abrasive firmly attached, ensuring long-lasting use under high heat and pressure.

This makes the belt suitable for dry metalworking applications, including light grinding, deburring, and finishing on carbon steel and stainless steel. The abrasive quality supports consistent, efficient work.
