NORTON A275 SPEEDGRIP VAC DISCS. A275 Sandpaper cuts faster, runs cooler, resists loading better and lasts longer than any other conventional sandpaper. These discs are a popular choice for sanding paint, primer and primer surfacer; also for deburring, removing sand scratches, shaping and finishing plastic filler, and feather-edging repaired areas. Special No-Fil Speed Grip coating prevents premature loading and vacuum holes allow the discs to be used on vacuum sanders.
