Trizact™ 7010309562 Narrow Cloth Belt, 2 in W Belt x 72 in L, A300 Grit, Fine Grade, Cloth Backing

Our 3M™ Trizact™ cloth belt 337DC delivers consistently in intermediate to final finish, medium pressure applications. Designed with aluminum oxide and a grinding aid on a durable X- weight cloth backing, this belt is available in widths from 1/2 to 24 in and grades from A300 to A30. Our 3M™ Trizact™ cloth belt 337DC owes its durability and consistent sustained cut rate to its uniquely engineered "bricks and channels" macro replicated abrasive structure. Uniform abrasive "bricks" keep fresh cutting mineral constantly at the working surface and "channels" sweep debris away to discourage loading and keep the substrate clean. The "bricks" consist of layers of mineral and grinding aid, up to 4 times as much as conventional aluminum oxide belts of the same grade. These dense layers of abrasive mineral lead to extra long life and extremely consistent performance. The grinding aid protects heat sensitive alloys from damage and reducing rework. Trizact™ belts start sharp and stay sharp. In many cases, Trizact™ 337DC has the capacity to grind and finish in one step. Building upon the principles of micro replication, 3M™ scientists developed larger, more diverse abrasive structures cubes, spheres, ridges identical in shape and optimized for a variety of applications. Micro replication allows 3M™ to design abrasives with varying shapes and formulations, to control the level of breakdown, cut, finish and life. These abrasive structures are arrayed precisely and uniformly across a film or cloth backing in a pattern calculated to deliver sustained cut rate and eliminate belt to belt variation. Trizact™ was developed especially for finishing more difficult processing materials like titanium, cobalt, stainless steel, as well as all exotic alloys in the aerospace, aviation and medical industries. Also effective for finishing applications on carbon steel, copper, bronze, aluminum, composite materials and synthetics. Use for dry intermediate finishing, blending, scratch refinement or final dimensioning on robotic, semi-automated, automated, off-hand equipment and portable file belt tools. To prepare drawn carbon steel truck exhausts from rough to pre-plate finishes in as few steps as possible, we used a grade sequence of A100, A65, A30. Trizact™ 337DC outlasted a competitor by 2:1. For blending, final dimensioning and finishing of turbine engine components, our grade A45 Trizact™ 337DC belt outlasted a competitor's belt by 4:1 times and produced a finer finish. Micro replication is only one of 3M™ platform of core technologies. Its perfectly calibrated arrays are designed to give materials new physical, chemical, or optical properties. The science that makes 3M™ structured abrasives wear more evenly, last longer and provide more pristine finishes on delicate components like medical implants is also the science that makes traffic signs brighter, and exterior building illumination capture and reflect light more brilliantly.
