Cubitron II Roloc Fibre Disc 786C (33389) – 3 in, 36+ Grit, 15 Pack | High Performance

Cubitron II Roloc Fibre Disc 786C, 33389 is designed for professional metalworking tasks such as grinding, cutting spot welds, deburring, and shaping. Built with Precision-Shaped Grain PSG technology, it delivers a uniform cut and maintains sharpness as the grains self-fracture during use.

Fast, clean performance you can rely on

• Faster cutting: around 30% quicker than conventional ceramic discs on average, helping you move through material faster
• Long life: the disc lasts longer, reducing interruptions in tough manufacturing and finishing cycles
• Fewer changes: the Roloc attachment enables quick, tool-free disc changes to keep your workflow moving
• Uniform abrasive: PSG technology provides a consistent cut across painted and bare metal surfaces
• Resilient backing: stiff fiber backing with a strong resin bond resists tearing and supports extended disc life
• Maintains sharpness: the grain self-fractures during use to help sustain cutting action over time

Real-world workflows

In automotive and fabrication shops, the Cubitron II disc handles heavy stock removal, deburring, and contour shaping with predictable results. The combination of fast material removal and a stable finish can help operators complete tasks with fewer tool changes and less rework. The 3-inch size fits common Roloc setups, making it a practical choice for handheld grinding, shaping curved profiles, and refining welds.

Field tests show consistent performance when working through coatings, rust, and minor imperfections. The disc’s resin bonding and stiff backing contribute to reliable life under demanding conditions, while the PSG grain maintains cutting efficiency across multiple passes. This means you may experience smoother progress from rough to refined, with fewer passes required for similar results.
