Frequently Asked Questions

  • Q: Are these discs compatible with all Inland Twin Spin grinder models?
    A: These 5" diamond grinder discs are designed as direct replacements for standard Inland Twin Spin grinder disc sizes. Always verify your specific Inland grinder model disc diameter and arbor specifications before ordering to ensure correct fit.
  • Q: What grit disc should I start with for stained glass grinding?
    A: Start with the 60 grit disc for initial shaping and cutting to pattern lines, then switch to the 180 grit disc for smoothing edges and refining curves. Use the 360 grit disc for final edge smoothing before foiling or leading. Always run water over the disc during grinding.
  • Q: Should Inland Twin Spin diamond discs be used wet or dry?
    A: Always use wet. The Inland Twin Spin grinder has a built-in water reservoir that keeps the disc wet during grinding - essential for cooling the diamond edge, preventing glass chipping, and extending disc life. Never run diamond grinder discs dry.
