Speed, Long Life, and Ease of UseEngineered for faster cutting, sustained performance, durability and increased throughput, our 3M™ Cubitron™ II Roloc™ Fibre Discs 786C is a game changer, featuring our Precision-Shaped Grain technology.About 3M™ Cubitron™ II and Precision-Shaped Grain3M™ Cubitron™ II abrasive discs, cutoff wheels and file belts have raised the bar for high-performing abrasives. 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 30% faster and lasts 2x longer than conventional ceramic abrasives.Time-Saving Quick Change AttachmentOur 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 Fibre Roloc™ Discs with 3M™ Power Tools. 3M abrasives, accessories and power tools are optimized to work together and help you attain maximum productivity.Recommended ApplicationsChoose 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.Clean and remove coatingsDeburr metalRemove gasketsPolish and shape metalRemove oxidation, paint and rustCut spot weldsStrip paint to metalSlotted for cutting off weld and door skin removalTech TipUse 3M™ Disc Pad Face Plates - Red Ribbed - to optimize product life of Cubitron™ II Fibre Discs - grades 36+, 60+ and 80+.A Portfolio of Abrasive Systems SolutionsFrom specialty abrasives designed for a highly specific purpose to versatile sheets, 3M provides an abrasive to accomplish your task or perfect your system.
