3M-237AA Trizact Abrasive Belts

The 3M™ Trizact™ 237AA cloth sanding belt is the right choice for consistently precise results in surface finishing. The special pyramid-shaped microstructure of micron-grade aluminum oxide ensures that new, sharp grit is exposed layer by layer during sanding. This keeps cutting performance consistently high and achieves a uniform, fine finish.

The belt runs significantly cooler than conventional abrasives, protecting workpieces from overheating. At the same time, it impresses with a noticeably longer service life. The durable yet flexible X-weave backing adapts perfectly to curves, edges, and contoured surfaces. This makes it particularly suitable for fine grinding, intermediate grinding, and polishing prior to subsequent coatings or paint applications.

The resin-bonded grit layer is heat-resistant and prevents grit loss even under heavy loads. Uniform grit distribution reduces the number of required processing steps and saves valuable time. In addition, the film backing ensures low-vibration, smooth operation without chatter marks.

Compared to standard abrasives, the 3M™ Trizact™ 237AA delivers up to five times longer service life, a finer finish, and greater process reliability—an efficient sanding belt for professional demands.
