Frequently Asked Questions

  • Q: What size flexible diamond sanding belt do I need for my glass grinder or lapidary belt sander?
    A: For most hobby lapidary belt sanders and glass grinders, the most common belt sizes are 1"x30", 1"x42", 2"x72", and 762mm x 25mm (metric). Check your machine’s specification plate or owner’s manual for the exact belt dimensions required. Our collection covers sizes from 1/2"x18" through to industrial 3500mm x 150mm — contact us if you need a size not listed for your specific machine.
  • Q: Can flexible diamond sanding belts be used to grind and polish glass edges without chipping?
    A: Yes — flexible diamond sanding belts are widely used for glass edge grinding and polishing in glass fabrication, stained glass work, and architectural glass processing. Use coarser grits (60–120) for initial edge shaping and removing saw marks, medium grits (240–600) for edge smoothing, and fine grits (800–1800) for polished glass edges. Always use wet with water cooling to prevent glass chipping and extend belt life.
  • Q: What is the difference between arrow pattern and dot pattern flexible diamond belts?
    A: Arrow pattern belts have a directional diamond coating that channels swarf away from the cutting zone — better for high-speed production grinding where efficient swarf evacuation is critical. Dot pattern belts have a uniform diamond distribution for consistent all-direction cutting — better for hand-held and multi-direction grinding applications where the belt direction changes frequently. For most lapidary and glass grinding applications, dot pattern belts provide more versatile performance.
  • Q: Are flexible diamond sanding belts suitable for grinding granite and marble countertop edges?
    A: Yes — flexible diamond sanding belts are used professionally for grinding and polishing granite, marble, and engineered stone countertop edges and surfaces. Use coarse grits (60–120) for initial edge shaping, medium grits (240–600) for surface smoothing, and fine grits (800–1800) for pre-polish preparation before diamond compound or resin pad final polishing. Always use wet with continuous water cooling for stone grinding applications.
  • Q: Can I order custom size flexible diamond sanding belts for my industrial grinding machine?
    A: Yes — we supply industrial customers with custom-length and custom-width flexible diamond belts for specific machine configurations. Contact us directly with your required belt dimensions (length x width), grit, and pattern preference for a custom belt quotation. We regularly supply custom sizes for glass processing lines, stone fabrication equipment, and specialized industrial grinding machines.
