Abrasives and Surface Conditioning

3M™ Cloth Belt 577F, 100 YF-weight, 52 in x 75 in, Film-lok, Single-flex. When traditional aluminum oxide belts aren’t cutting it, try 3M™ Cloth Belt 577F with alumina zirconia abrasive grain. It offers increased cutting efficiency compared to aluminum oxide, and has a heavy, water-resistant polyester backing that stands up to high-pressure applications and edge work.

3M™ Trizact™ Cloth Belt 237AA, A30 X-weight, 3 in x 132 in, Film-lok, Full-flex, Scallop B. 3M™ Trizact™ Cloth Belt 237AA uses proprietary microreplication technology by 3M where micron-graded aluminum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on an X weight cloth backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish.
