3M-237AA Sanding Belts

The 3M™ Trizact™ 237AA abrasive cloth guarantees consistent results and a long service life. The unique micron-grade aluminum oxide pyramid structure ensures that fresh cutting edges are continuously exposed during sanding. This maintains consistent cutting performance and enables a fine, precise finish.

Compared to standard abrasives, the Trizact™ belt runs cooler, protects workpieces from overheating, and offers a significantly longer service life. The flexible and durable X-weave backing easily conforms to contours and irregular surfaces. This makes the belt ideal for intermediate sanding, fine sanding, and polishing prior to subsequent painting or coating.

The resin-bonded abrasive layer is heat-resistant and prevents grain loss even under heavy use. Thanks to the uniform grain distribution, the number of processing steps is reduced, saving time and costs. The film backing also ensures stable, vibration-free belt operation without chatter marks.

With a service life up to five times longer than conventional sanding belts, a uniform sanding finish, and high process reliability, the 3M™ Trizact™ 237AA is an efficient choice for professional sanding jobs.
