• 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 is a reliable choice for metalworking tasks. This model features a P120 J-weight grade that balances durability and flexibility, making it suitable for various grinding and finishing jobs.

Designed specifically for use on backstand grinders, file belt tools, and benchtop motors, this belt delivers consistent performance. Its aluminum oxide abrasive ensures fast cutting on most metals.

Flexible J-Weight Backing

This belt uses a J-weight cloth backing that provides excellent flexibility. The full-flex design allows it to conform well to contours and complex parts, improving blending and finishing results.

Such flexibility is ideal for light grinding, deburring, and setting the grain on carbon steel, stainless steel, and softer metals like aluminum and brass. The backing supports smooth operation on detailed surfaces.

Optimal 3 Inch Width

Measuring 3 inches wide by 132 inches long, this belt fits a range of standard sanding equipment. The size offers a good balance between coverage and control for various metalworking applications.

Its dimensions make it practical for both benchtop and portable tools, ensuring versatility. The length supports extended use before replacement, enhancing productivity.

Film-Lok Open Coat

The Film-lok technology features an open coat construction that spaces abrasive grains apart. This design helps evacuate sanding dust and swarf, reducing loading and maintaining aggressive cutting action.

Open coat belts like this one provide longer abrasive life and better visibility during work. They are especially effective on soft metals such as bronze and copper, where clogging can be an issue.

Convenient 25 Pack Case

This product comes in a case of 50 belts, each pack containing 25 belts. Such packaging is ideal for workshops needing a steady supply of abrasives without frequent reordering.

The bulk pack supports continuous operations and reduces downtime. It’s a cost-effective option for professionals who rely on consistent belt availability for their metalworking tasks.
