New 2" x 72" 3M 307A Premium Cubitron Abrasive Sanding Belts Grade A65 5 pack.

3M Trizact Cloth Belt 307EA uses proprietary microreplication technology where micron-graded aluminum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on a rayon backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish.

Details:

Three-dimensional design enables very consistent finishes throughout the abrasive life in robotic applications

Self-sharpening pyramids start sharp, stay sharp, and run cooler than conventional abrasives

Flexible backing flows over contoured surfaces for consistent finishing

Ideal for intermediate finishing and fine polishing prior to plating or buffing

Produces finer finishes than conventional electrostatically coated abrasives
