    Anything extra you need to know

  • Aluminum oxide is a very hard mineral that maintains sharp points on the grains much longer than natural abrasives such as emery or garnet
  • Open coat construction helps minimize the buildup of dust on the surface of the paper, which would otherwise load the abrasive points
  • Loading often results from sanding soft materials and can clog the abrasive, shortening the usable life of the sandpaper sheet.
  • What makes this product special

  • Tough aluminum oxide abrasive cuts fast and performs well on many surfaces
  • Load-resistant open coat construction enables longer use before replacement
  • Strong, D-weight paper backing supports aggressive sanding
  • Sheets are conformable to various workpieces and usable by either hand or machine
  • Sheets come in a number of sizes to accommodate various applications
  • We suggest you should use it for:

  • Blending?, Prepping Metal Prior to Paint?
