This disc with its tough hard sharp ceramic abrasive lasts significantly longer than conventional ceramic grain discs, making it ideal for grinding, weld blending, deburring and similar tough metal finishing jobs. Use 3M™ Cubitron™ II Roloc™ Fibre Disc 786C for grinding, weld blending, deburring and other tough metal finishing jobs. The 3M™ Cubitron™ II Roloc™ Fibre Discs 786C is engineered for speed, long Life, and ease of use, for faster cutting, sustained performance, durability and increased throughput. Cubitron™ Abrasives feature our Precision-Shaped Grain (PSG) technology, which allows our engineers to control the geometry of the abrasive grain for a truly fast, efficient cut. Instead of simply crushing the abrasive into particles, 3M uses microreplication to uniformly size ceramic grains and precisely shape them into triangular structures - essentially, sharp peaks that slice, not plow, through paint and metal. These grains are electrostatically oriented on the abrasive surface for the most efficient cut and even wear. What’s more, PSG fractures during use to maintain sharp abrasive edges. The result: Cubitron™ II cuts faster and lasts longer than conventional ceramic abrasives. Our 3M™ Fibre Roloc™ Disc Quick Change Attachment System is convenient and saves time. Discs screw securely into the threaded mandrel without tools. Ideal for applications requiring frequent grade or disc size changes. For best results, use 3M™ Fibre Roloc™ Discs with 3M™ Power Tools. Choose the 3M™ Cubitron™ II Roloc™ Fibre Discs 786C for medium to heavy-duty metalworking such as weld grinding and clean-up, as well as edge chamfering, beveling, and paint removal processes. ## Features - For industrial/occupational use only.
