Self-sharpening pyramids start sharp, stay sharp, and run cool Flexible backing flows over contoured surfaces for consistent finishing Produces a fine finish The 3M™ Trizact™ Cloth Belt 307EA uses the 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.
