Why this product
Faster Material Removal
DEWALT states up to 3× faster removal than its referenced fiber-resin metal sanding discs.
Longer Abrasive Life

Type 29 Grinding Angle
The fiberglass backing is designed for a 20°–25° working angle.
Three Grit Choices
The family lets the buyer select 40, 60, or 80 grit without changing disc diameter or arbor size.
CHOOSE WITH CONFIDENCE
Which grit should I choose?
40 grit is the coarsest option for the most aggressive material removal.
60 grit is the middle choice when removal and surface control both matter.
80 grit is the finest option in this family for lighter removal and a more refined result.
Follow the coating or repair process when a required scratch profile is specified; do not select grit from appearance alone.
