- 3M Cubitron II Roloc fiber discs 786C is built for grinding, weld blending, deburring and other tough metal finishing jobs. 3M precision shaped Grain - a tough, hard, sharp ceramic abrasive - is resin bonded to a stiff fiber backing. This disc lasts significantly longer than conventional ceramic grain discs, delivering a lower cost per grind with fewer disc changes.
- Features:
- Cubitron II cuts 30% faster and lasts 2x 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

Q: What tools are compatible with these 2-inch Roloc discs?
A: They are compatible with Roloc disc pads and right-angle tools or die grinders rated for speeds up to 25,000 RPM.
Q: What materials are suitable for grinding with this disc?
A: These discs are ideal for carbon steel, stainless steel, and other hard metals used in body repair and fabrication.
Q: Is the 36+ grit appropriate for finishing or only rough grinding?
A: 36+ grit is designed for aggressive stock removal and weld blending, not for fine finishing.
Q: Can these discs be used wet or dry?
A: They are designed for dry use and not recommended for wet applications.
Q: What makes Cubitron II discs different from traditional abrasives?
A: The precision-shaped ceramic grain forms sharp, fast-cutting tips that self-sharpen during use, ensuring longer life and consistent performance.
