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 P180 J-weight grade, ensuring a balance between cutting power and flexibility for various jobs.

Designed specifically for use on backstand grinders, file belt tools, and benchtop motors, this belt delivers consistent performance. Its brand reputation assures quality and durability in demanding environments.

Flexible Backing Benefits

This belt uses a full-flex cloth backing that conforms easily to contours and complex parts. The flexibility helps achieve smooth blending and finishing on irregular surfaces without damaging the workpiece.

Its 2 inch by 132 inch size provides ample length for extended use, making it suitable for detailed metal shaping and finishing tasks where precision is key.

Open Coat Construction

The Film-lok open coat design helps clear sanding dust from the belt surface, preventing clogging. This feature allows for a more aggressive cut and extends the abrasive life, boosting productivity.

Open coat belts like this one are especially effective on soft metals such as aluminum, brass, bronze, and copper, where dust buildup can reduce sanding efficiency.

Durable Aluminum Oxide Abrasive

Equipped with tough aluminum oxide abrasive, the 3M 302D belt cuts quickly and performs well on most metals. This abrasive type is known for its long life and fast cutting ability.

The resin bonded abrasive ensures the grains stay attached under heat and pressure, making the belt suitable for dry metalworking applications and consistent use.

Convenient Pack Size

This product comes in a case of 50 belts, each measuring 2 in x 132 in. The pack size supports high-volume operations and reduces the need for frequent reordering.

Having 25 belts per pack within the case allows for easy inventory management and ensures you have enough belts on hand for continuous work without interruption.
