3MTM FIBER DISC 982C 4-1/2" X 7/8" PRECISION SHAPED CERAMIC GRAIN 36+ GRIT OUR 3MTM CUBITRONTM II FIBER DISC 982C IS WELL-SUITED FOR EDGE CHAMFERING, BEVELING, AND REMOVING CARBON STEEL WELDS, MILL SCALE, PITS AND IMPERFECTIONS, MACHINING GROOVES, AND MORE. PROPRIETARY CUBITRONTM II PRODUCTS HAVE RAISED THE BAR FOR HIGH-PERFORMING ABRASIVES. 3M ENGINEERS STARTED WITH 3MTM CERAMIC ABRASIVE GRAIN AND USED 3M PRECISION SHAPED GRAIN TECHNOLOGY TO GENERATE TRIANGULAR SHAPED GRAINS THAT ARE ELECTROSTATICALLY ORIENTED ON THE BACKING TO FORM SHARP PEAKS AND MAXIMIZE CUTTING POTENTIAL. THESE PEAKS ACT LIKE INDIVIDUAL CUTTING TOOLS THAT SLICE THROUGH METAL, AND CONTINUOUSLY SHELF-SHARPEN AS THE POINTS BREAK OFF. THE GRAINS WEAR EVENLY AND SELF-SHARPEN, REDUCING HEAT DUE TO FRICTION FOR UP TO TWICE THE LIFE OF OTHER FIBER DISCS, WITH LESS GRINDING PRESSURE. THE RESULT IS THAT CUBITRONTM II DISCS OUTCUT AND OUTLAST EVERY CONVENTIONAL CERAMIC INDUSTRIAL ABRASIVE DISC ON THE MARKET, MAXIMIZING PRODUCTIVITY AND MINIMIZING OPERATOR FATIGUE. FIBER DISCS ARE HEAVY-DUTY DISCS IDEAL FOR WELD REMOVAL, GRINDING, AND BLENDING LARGE AND SMALL AREAS OF METAL SURFACES. THEY FEATURE A TOUGH, STIFF BACKING MADE FROM VULCANIZED FIBER THAT RESIST WEAR AND CAN HANDLE TOUGH GRINDING APPLICATIONS. PRIMARY APPLICATION IS METALWORKING
