8" Hookit 737U Cubitron II 8-Hole Dust Free Purple Disc - 40+ (25 per Box)

These discs feature 3M's Cubitron II - a revolutionary advancement in abrasive technology.
Use them for paint stripping, body filler sanding, fine featheredging, final sanding before priming, prepping before blending, and more.

Note that unlike other Hookit Cubitron II Purple Sanding Discs, this 6" 40 grit disc has an 8-Hole Dust Free hole pattern.

The Cubitron™ II abrasive used in these discs is a unique, precision-shaped, ceramic grain that is engineered with ultra-sharp, fast-cutting points.
An improvement over the original Cubitron, the sharp-edged, pyramid-shaped Cubitron II grains are electrostatically oriented so they point upward to form sharp peaks.
They act like individual cutting tools that slice right through fiberglass, wood, paint, and body fillers,
As they wear, instead of getting rounded, the pyramid-shaped peaks continuously fracture to form brand new, sharp, cutting edges — running cooler and maximizing both performance and disc life.
By contrast, conventional ceramic abrasive grain is irregular in shape. Instead of a clean slicing action, the grain "plows" through the substrate, causing heat buildup, slower cutting and shorter disc life. See illustration at left.
