Buying Guide

  • Grit selection: Coarse grits (80–120) for material removal and shaping; mid grits (180–240) for finishing; fine grits (400) for final smoothing or prep before painting.
  • Adhesion quality: A strong, durable PSA backing reduces disc slip and dislodgement during aggressive sanding. Look for discs specifically described as self-adhesive with good holding power.
  • Backing and material: Aluminum oxide is common and suitable for wood, metal, and plastics. Zirconia variants offer longer life on metals or tougher substrates; check the product notes for compatibility.
  • Disc count and organization: Larger assortments save time and money; organized packs help you quickly locate the right grit for the task.
  • Compatibility: Confirm the discs fit your 6-inch DA or orbital sander with PSA backing and quick-release tabs, if applicable.
  • Usage tips: Avoid excessive pressure, especially on finer grits; use progressive grits to minimize loading; clean discs regularly to maintain performance.
