Frequently Asked Questions

• Q: What diamond tools do I need for stained glass grinding?
  A: For stained glass grinder work, diamond grinder head bits are the primary tool — available in Standard, Radius Angle, Radius Edger, Reducing, Ripple, Helix, Fast, and Jewelry Groove profiles at $15 each. After grinding, use diamond hand pads (120–1800 grit) for edge smoothing, then cerium oxide on a felt pad for final edge polish.
• Q: What grit sequence should I use for polishing a glass edge?
  A: Start with 120–240 grit diamond hand pads or sandpaper sheets to remove grinder marks, progress through 400, 600, 800, 1200, 1500, 1800 grit for surface refinement, then apply cerium oxide polishing compound on a felt or polyurethane pad for the final mirror finish.
• Q: Can I use diamond sanding belts on glass?
  A: Yes — flexible diamond sanding belts are effective for glass edge sanding and surface finishing on belt sanders. Use water cooling and consistent feed pressure. Available in 2130mm and 2400mm lengths across 240–1800 grit for progressive glass finishing sequences.
• Q: What is the best polishing compound for glass?
  A: Cerium oxide is the standard final polish compound for glass — it produces a high-clarity mirror finish when used on a felt or polyurethane polishing pad as a water slurry on a rotating pad.
• Q: Can tempered glass be ground and polished?
  A: Tempered glass edges can be lightly polished with fine diamond hand pads and cerium oxide, but aggressive grinding or cutting of tempered glass will cause it to shatter due to internal stress. Do significant edge work before tempering if required.
