3M Trizact PSA Cloth Disc 237AA features sharp-cutting aluminum oxide mineral adhered to an X-weight, water-resistant polyester cloth backing. Made using microreplication technology, this abrasive works well for a range of low- to medium-pressure applications: finishing, polishing, blending and deburring. It can be used on many metals, including mild and stainless steel.

Working Hard for You
3M Trizact PSA Cloth Disc 237AA has two characteristics that make it desirable for your finishing, polishing, blending and deburring needs: microreplication technology and a PSA attachment. Let’s begin with microreplication technology.

3M Science, Applied to Microreplication Technology
3M Trizact Abrasives feature an engineered surface of patterned, microscopic three-dimensional structures resembling pyramids. As the abrasive is used, the tops of the pyramids wear away, continually exposing fresh mineral. This cycle of renewal ensures a consistent cut rate and finish throughout the long life of the disc. 3M Trizact PSA Cloth Disc 237AA, specifically, features micron-graded aluminum oxide particles formed into pyramids and adhered to an x-weight backing. The x-weight backing is durable and stiff; it prevents the abrasive from yielding when it comes in contact with the workpiece, so you get a thorough and aggressive cut.

Easy, Swift Power Tool Attachment
In addition to micron-graded aluminum oxide, 3M Trizact PSA Cloth Disc 237AA has a pressure-sensitive adhesive backing. Applying 237AA to your power tool is as simple as applying light pressure and adhering the disc to a backup pad (sold separately). When the work is complete, the disc can be removed cleanly and easily. We included the PSA backing on 237AA to help operators enhance their productivity and throughput.

Altogether, our 3M Trizact PSA Cloth Disc 237AA is a sharp-cutting, ready-to-use abrasive designed to help you maximize your efforts and get the most out of your work.
