3M™ Trizact™ Cloth Belt 237AA, A45 X-weight, 1-1/2 in x 376 in, Film-lok, Full-flex

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.
