3M-237AA Sanding Belts

The 3M™ Trizact™ 237AA cloth sanding belt offers consistent performance and a precise finish. Its microstructured aluminum oxide pyramids in micron quality continuously expose new cutting edges during sanding. This ensures consistently high cutting performance and produces a reproducible, fine finish.

Compared to conventional abrasives, the belt runs cooler, protects the workpiece from overheating, and delivers a significantly longer service life. The durable, flexible X-fabric backing ensures a clean fit to contours, curves, and shaped surfaces. This makes the sanding belt ideal for fine sanding, intermediate sanding, and polishing prior to painting or coating.

The resin-bonded grit layer is heat-resistant and prevents grit loss even under heavy use. The even grit distribution reduces the number of sanding passes required, saving time and costs. In addition, the film backing ensures low-vibration belt operation and prevents annoying chatter marks.

With up to five times longer service life compared to standard abrasives, consistently high cutting performance, and efficient machining, the 3M™ Trizact™ 237AA is the perfect solution for professional sanding processes.
