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 sheets typically last significantly longer than standard aluminum oxide abrasives — often 2x or more — because the ceramic grain self-sharpens rather than dulling.
How much material is on the roll?
Each roll provides 8.75 yards (26.25 feet) of 2.75-inch wide abrasive.
