Scotch-Brite Cut and Polish Disc D5 4 x 1 1/4 Aluminum Oxide A MED

3M scotch-brite cut and polish disc d5 4in x 1 1/4in aluminum oxide a med our scotch-brite cut and polish disc d5 uses a durable, non-woven, open-web construction is load resistant, runs cool, and provides conformability while the aluminum oxide abrasives work to deliver consistent cutting action. The 1/4in shank is suitable for power tools with a 1/4in drive, die grinders, and inline sanders. We chose aluminum oxide abrasive, which is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys. Our scotch-brite industrial abrasives are a unique surface conditioning product with abrasives incorporated into non-woven nylon or other synthetic fibers. Combining abrasives into the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers. Applications are fine finishing, finishing, refining, straightline - brushed finish builders hardware, medical instruments, metal fabrication, metal implants, plumbing fixtures, turbine engines. Industries include builders hardware, medical instruments, metal fabrication, metal implants, plumbing fixtures, turbine engines.
