Speed, Long Life, and Ease of Use
Engineered 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 Grain
3M™ 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 Attachment
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 Fibre Roloc™ Discs with 3M™ Power Tools. 3M abrasives, accessories and power tools are optimized to work together and help you attain maximum productivity.
