3M™ Trizact™ Disc 237AA combines the fine finishing qualities of aluminum oxide minerals with a durable X-type backing. Our 237AA abrasive discs are ideal for workpieces that require aggressive sanding but a fine finish.
Use the 3M™ Trizact™ Disc 237AA to finish and polish stainless steel, carbon steel, alloys with high concentrations of nickel, titanium and aluminum. Our 237AA abrasive discs are designed for touch-ups and final refinements at the end of a work sequence. The X-type support provides resistance and rigidity. This abrasive retains its strength when folded or rolled, so it won't break or peel. It is ideal for workpieces that have already been shaped and prepared by grinding and deburring, as (at this stage of the process) the parts typically require an abrasive that will not warp or deflect while being processed. uses. Aluminum oxide mineral has a sharp cut, but leaves a smooth cut pattern, ultimately producing a smooth, clean finish. 3M Trizact abrasives revitalize light sizing and finishing work by reducing process steps, increasing productivity and creating consistency. Great advantages are obtained through a 3M technology called “micro-replication.” During micro-replication, small three-dimensional pyramid-like structures are attached to the support. These pyramids contain layers of mineral that begin to break down after several uses, continually exposing renewed ore. This mineral renewal cycle maintains the cutting quality of the abrasive. Continuous sharp cutting action reduces the need to change abrasives, helping to increase performance and productivity. Additionally, because the mineral is evenly distributed over the surface of the abrasive, the workpiece receives constant (rather than erratic) contact for a consistent cut. From medical implants and surgical instruments to automotive transmission components, 3M Trizact abrasives are uniquely suited for projects with strict technical requirements, consistently delivering a consistent finish.
