3MTM CUBITRONTM II FLAP DISC 967A 4-1/2″ X 5/8-11 T27 CERAMIC GRAIN 60+ GRIT CUBITRONTM II 967A FLAP DISC CAPITALIZES ON OUR PROPRIETARY 3M PRECISION SHAPED GRAIN TECHNOLOGY TO DELIVER SUPERIOR CUT RATES, WHILE THE FLEXIBILITY OF THE FLAP CONSTRUCTION ENABLES GRINDING AND BLENDING IN A SINGLE STEP. BECAUSE OUR 3M PRECISION SHAPED GRAIN GENERATES AN EXCEPTIONALLY HIGH CUT-RATE WITH LESS PRESSURE, OPERATORS CAN FINISH TOUGH TASKS LIKE WELD GRINDING, DEBURRING, RUST REMOVAL, EDGE GRINDING, WELD SEAM BLENDING, AND DEBURRING FASTER AND WITH LESS FATIGUE. A HEAT-ACTIVATED GRINDING AID ON THE DISC MAKES THIS AN OUTSTANDING PRODUCT FOR ALL TYPES OF METAL—IT HELPS KEEP THE DISC COOLER ON STAINLESS STEEL AND HEAT-SENSITIVE METALS SUCH AS NICKEL ALLOYS AND TITANIUM, THEREBY REDUCING METAL DISCOLORATION/OXIDATION AND THE CHANCE OF HEAT-RELATED STRESS CRACKS.   THE SUPERIOR PERFORMANCE AND DURABILITY OF 3M PRECISION SHAPED GRAIN IS ENHANCED BY A UNIQUELY DESIGNED HEAVY Y-WEIGHT POLY-COTTON BACKING THAT ENABLES CONTROLLED, EVEN WEAR WITH NO PREMATURE DULLING OR GLAZING, SO OPERATORS CAN ACCOMPLISH MORE THROUGHPUT PER DISC. FLAP DISCS RUN ON A RIGHT ANGLE GRINDER. FOR ATTACHMENT, 4-1/2″ FLAP DISCS WITH A CENTER HOLE REQUIRE A FLAP DISC ADAPTER NUT, AND 7″ DISCS REQUIRE A FLAP DISC HOLDER (BOTH SOLD SEPARATELY). DISCS WITH A 4-1/2″ DIAMETER HAVE A MAX RPM OF 13,300, AND 7″ DISCS HAVE A MAX RPM OF 8,600. USE TYPE 27 ON FLAT SURFACES OR OUTSIDE EDGEWORK. 3MTM CUBITRONTM II PRODUCTS HAVE RAISED THE BAR FOR HIGH-PERFORMING ABRASIVES. 3M PRECISION SHAPED GRAIN OUTCUTS AND OUTLASTS CONVENTIONAL CERAMIC INDUSTRIAL ABRASIVES AND REQUIRES LESS GRINDING FORCE TO ACHIEVE SUPERIOR PERFORMANCE. THE RESULT IS THAT OPERATORS CAN GRIND FASTER AND COMPLETE MORE PARTS PER DISC WITH LESS MUSCLE-WORK AND FATIGUE.   TO CREATE 3M PRECISION SHAPED GRAIN, OUR DESIGN ENGINEERS STARTED WITH 3MTM CERAMIC ABRASIVE GRAIN AND USED PROPRIET
