Buying Guide: 17 Inch Floor Sanding Discs

What should you consider when choosing 17″ sanding discs?

  • Grit range: Start with coarser grits (36X, 60) for heavy removal and move to finer grits (80, 150) for finishing and prep.
  • Backing and construction: Cloth backings are durable for repeated use; mesh screens reduce clogging and extend life under heavy dust.
  • Compatibility: Ensure the disc has a 2″ center hole compatible with standard floor sanders or drive pads.
  • Application surface: Wood floors vs. concrete requires different grit sequences and disc types for optimal results.
  • Durability vs. cost: Higher-quality discs may cost more upfront but save time and disc changes on large projects.
  • Dust and clogging: Mesh screen discs minimize loading but may wear faster on rough surfaces.
