• 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 designed for reliable performance with a flexible J-weight backing. This model offers excellent conformability, making it ideal for blending and finishing complex parts. Its design suits backstand grinders, file belt tools, and benchtop motors.

With a P320 grade, this belt balances cutting efficiency and finish quality. The cloth backing supports flexibility while maintaining durability, ensuring consistent results on various metalworking tasks.

Precise Size And Format

This belt measures 1-1/2 inches by 42 inches, providing a versatile size for many sanding applications. The Film-lok format enhances belt tracking and grip, improving user control during operation.

Its dimensions fit standard sanding equipment, making it a practical choice for shops needing consistent, easy-to-use abrasives. The size supports detailed work on contours and edges.

Open Coat Construction Benefits

The open coat design helps clear sanding dust from the belt surface, preventing clogging and maintaining aggressive cutting action. This feature extends abrasive life and boosts productivity during metalworking.

This construction is especially effective on soft metals like aluminum, brass, bronze, and copper. It also improves visibility and belt performance by channeling dust away from the workpiece.

Durable Aluminum Oxide Abrasive

Featuring tough aluminum oxide abrasive, this belt cuts fast and performs well on most metals. The resin bond secures abrasive particles firmly to the cloth backing, resisting heat and pressure.

This mineral choice is popular for its long life and versatility, suitable for light grinding, finishing, and deburring on carbon steel, stainless steel, and soft metals.

Bulk Pack Of Two Hundred

This product comes as a case of 200 belts, ideal for high-volume use or stocking up for ongoing projects. The large pack size ensures you have a ready supply for continuous work without frequent reordering.

Having 200 belts on hand supports efficient workflow in busy workshops, reducing downtime and keeping operations running smoothly with consistent quality abrasives.
