Sand quickly while capturing more dust than other vacuum discs. These discs have a precision-shaped abrasive that cuts easily and reduces heat to prevent wear. The grains continually fracture to expose fresh cutting edges while keeping their engineered points and angle. Discs have mesh backing to clear dust and prevent buildup that can dull the abrasive. A hook-and-loop mount lets you switch grits without waste, unlike adhesive-backed discs. Pair with a compatible backup pad and sander.
