Product Details
The 3M™ Trisect™ cloth belt 237AA measures 4" x 132" and features A30 grit aluminum oxide abrasive with a resin structure formulated to break down under medium pressure, maintaining fresh, sharp mineral cutting for consistent finishes on hard metals such as carbon and stainless steel. It incorporates a grinding aid to prevent heat buildup, warping, and discoloration, and is built on an X-weight durable cloth backing that provides control, conformability, and effective medium-pressure grinding. The resin bonded abrasive enhances heat resistance and helps prevent delaminating. The belt uses a film media splice, a strong and secure bond consisting of thin film-joining media that minimizes chatter marks, ensuring smooth running and consistent finishing results. Proprietary Trisect™ abrasives produce finer finishes, faster results, and longer belt life compared to conventional abrasive products, starting sharp and staying sharp for improved, consistent quality. These belts can last up to five times longer than conventional discs and allow for reduced grade sequences, fewer process steps, and fewer abrasive products needed. The three-dimensional structures uniformly distributed over the abrasive surface eliminate disc-to-disc variations. Suitable applications include blending, centerless and cylindrical grinding, finishing, flat finishing, refining, and stroke sanding, serving industries such as builders hardware, medical instruments, metal fabrication, metal implants, plating and polishing, plumbing fixtures, and turbine engines.
