The 3M Trizact Cloth Belt 237AA uses proprietary microreplication technology 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.

• Self-sharpening pyramids start sharp, stay sharp, and run cool
• Flexible backing for consistent finish over contours
• For intermediate finishing and fine polishing prior to plating or buffing
• Produces a fine finish

The abrasive and resin structure of the 3M Trizact Cloth Belt 237AA is formulated to break down under medium pressure and keep fresh, sharp mineral cutting to provide consistent finishes on hard metals such as carbon and stainless steel. The belt also features a grinding aid that helps prevent heat buildup, warping and discolouration. The belt is constructed on an X-weight, durable cloth backing that helps provide control, conformability, and effective medium-pressure grinding. The resin bonded abrasive gives you greater heat resistance and helps prevent delamination. When compared to conventional abrasive products, proprietary 3M Trizact Abrasives produce a finer finish, achieve results faster, and last longer. The line of 3M Trizact Belts start sharp and stay sharp, resulting in more predictable finishes and improved, consistent quality. 3M Trizact Belts can last up to five times longer than conventional discs and provided precise finish control such that operators can reduce grade sequences, requiring fewer process steps and fewer abrasive products. Three-dimensional structures uniformly distributed over the entire surface of 3M Trizact Abrasives ensure consistent performance and eliminate disc-to-disc variation.
