3M-237AA Trizact Abrasive Belts

The 3M™ Trizact™ 237AA cloth sanding belt offers maximum precision and consistency during sanding. Its unique pyramid construction made of micron-grade aluminum oxide ensures that new, sharp cutting edges are continuously exposed during the sanding process. This keeps the removal rate constant throughout the entire service life and delivers a predictable, fine finish.

Unlike conventional abrasives, the Trizact™ belt runs cooler, thereby preventing material overheating. The robust yet flexible X-weave backing adapts perfectly to curved or textured surfaces, guaranteeing a uniform result. It is ideal for intermediate sanding, fine sanding, and polishing prior to further coating or painting.

The resin-bonded aluminum oxide is heat-resistant and ensures that the grit does not lose its shape even under heavy use. Uniform grit distribution reduces the number of required steps, saves time, and increases productivity. Additionally, the film backing ensures low-vibration operation and prevents unwanted chatter marks.

With a service life up to five times longer than conventional sanding belts and consistently high performance, the 3M™ Trizact™ 237AA significantly contributes to more efficient sanding processes and high-quality results.
