3M™ Cloth Belt 302D, 1/2 in x 30 in, P320 J-weight, Lap-Unskived, Single-Flex, 200 ea/Case

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. This belt is recommended for operations that require added flexibility.

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.

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.

• Tough aluminum oxide abrasive cuts fast and performs well on most metals
• 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
• Suitable for dry metalworking applications
• Resin bonded belt maximizes abrasive life
• Designed for use on backstand grinders, file belt tools and benchtop motors
