Frequently Asked Questions
What makes Cubitron II different from regular sandpaper?
Cubitron II uses precision-shaped ceramic grain that self-sharpens as it wears, cutting up to 2x faster and lasting up to 2x longer than conventional abrasives.
How long do Cubitron II sheets last?
Cubitron II typically lasts 2x or more compared to standard aluminum oxide abrasives because the ceramic grain self-sharpens rather than dulling.
How much material is on the roll?
Each roll provides 8.75 yards of 2.75-inch wide abrasive.
