Highlights
- Cubitron™ II cuts faster and lasts longer than conventional ceramic abrasives
- Precision Shaped Grain (PSG) technology employs microreplication for extremely uniform abrasive
- Triangular PSG abrasive grains are super-sharp and cut exceptionally fast
- Grains are electrostatically oriented on abrasive surface for efficient cut, even wear
- PSG self-fractures during use to maintain sharpness and prolong abrasive life
- Stiff fiber backing and a strong resin bond lend this disc long life and tear-resistance
- Significantly longer lasting, complete more parts per disc and requires fewer disc changes
3M’s Cubitron™ II Roloc™ Fibre Discs 786C is an abrasive disc featuring 3M™ Precision Shaped Grain resin-bonded to a stiff fiber backing. 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.
For best results, use Fibre Roloc™ discs with 3M™ Power Tools such as the 3M™ Pistol Grip Disc Sander (shown above)
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.
Wears evenly and provides super-long life and consistency at any grinding pressure
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.
