Sharp and Flexible 3M™ Cloth Roll 461F features a very sharp silicon carbide mineral that offers a great initial and sustained cut. It is bonded to a sateen-type, fully waterproof polyester cloth backing. If needed, the abrasive can be run wet or dry. The resin bond provides excellent mineral anchorage and high shelling resistance.Silicon carbide is a very hard, sharp and brittle mineral commonly used for low-pressure applications such as paint prep, the final stages of whitewood sanding and grinding applications on metal. It fractures easily, keeping its cutting edges sharp, and while it may have a shorter life than aluminum oxide, it produces a superior finish. It is used where the best possible finish is desired.Tips for Optimal Use3M™ Cloth Roll 461F can be cut and shaped according to project needs. It can be used with hand-held tools or electric and pneumatic power tools. 461F is offered in a range of grades, so operators can select the right grade for their application. Finer grades (P120 through P600) have an XF weight polyester backing. Coarser grades (P36 through P100) have a YF weight polyester backing. Regardless of grade or weight, cloth abrasives are known for both durability and agility. They can respond to workpiece contours without wearing and tearing easily.Altogether, 3M™ Cloth Roll 461F is a great match for operators seeking an abrasive that will rid the workpiece of tiny burrs and start setting the final finish without gouging or marring the workpiece.
