The 3M™ Trizact™ Cloth Disc 237AA features sharp-cutting aluminum oxide mineral bonded to a durable X-weight, water-resistant polyester cloth backing. This abrasive works well for a wide range of low- to medium-pressure applications like finishing, polishing, blending, and deburring. It can be used on many metals, including mild and stainless steel.For finishing and polishing stainless steel, carbon steel, high nickel alloys, titanium and aluminum, the 3M Trizact Cloth Disc 237AA ushers in those final touch-ups and refinements that come at the end of an abrasive sequence. Available in grades including A160, A100, A80, A65 A45, A30, A16, and A6, this disc delivers to the standard operators have come to expect from 3M Trizact Abrasives, but the mineral and backing set it apart. The X-weight backing is heavy, durable and stiff and prevents the abrasive from yielding when it comes in contact with the workpiece, so you get a thorough and aggressive cut. This cloth stays tough when bent or rolled and resists tearing and shelling. The 3M Trizact Cloth Disc 237AA is desirable for workpieces that have already been shaped and prepped by grinding and deburring, because parts often require an abrasive that won't yield or deflect when run. Ongoing sharp cutting action reduces the need to swap out the disc and contributes to higher thoroughput and greater productivity. And, because 3M Trizact Mineral is uniformly distributed over the abrasive surface, the workpiece receives fixed rather than erratic contact for a consistent cut. 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. From medical implants to surgical tools to automotive transmission components, 3M Trizact Abrasives are uniquely suited for projects with acute technical requirements delivering a consistent finish part after part.
