Flexible Diamond Discs

Flexible Diamond Discs - Color-Coded Diamond Sanding Discs for Flat Lap and Orbital Grinding

Our Flexible Diamond Sanding Discs feature nickel metal-plated diamond bond on a heavy-duty water-resistant polyester backing with an open dot or wave pattern for aggressive cutting with reduced loading. Color-coded by grit for instant identification, available in 6", 8", 10", and 12" diameters with 10 grit levels from 60 through 1800, and three backing options - magnetic, velcro, or plain - for compatibility with all standard flat lap machines and orbital sanders.

Frequently Asked Questions

  • Q: What is the difference between dot and wave pattern discs?
    A: Dot pattern discs allow swarf to escape in all directions - better for multi-direction grinding and hand-held applications. Wave pattern discs channel coolant and swarf more efficiently in one direction - better for machine grinding on flat surfaces.
  • Q: Which backing option should I choose?
    A: Choose magnetic backing for quick-change magnetic master lap systems. Choose velcro for orbital sanders and velcro backing plates. Choose plain for custom mounting with PSA adhesive.
  • Q: Can these discs be used wet and dry?
    A: Yes - the heavy-duty water-resistant polyester backing is designed for both wet and dry use. Wet use is recommended for stone, glass, and ceramic applications.
