Buying Guide: Glass Cutting Blades For Angle Grinders

Choosing the right blade depends on material type, thickness of cuts, and the work environment. Consider these factors:

  • Blade Thickness: Ultra-thin blades (around 0.05″ to 0.055″) reduce resistance and vibration, giving cleaner edges but may wear faster on hard materials.
  • Arbor Size: Most 4.5″ blades use a 7/8″ arbor. Verify compatibility with your grinder’s arbor and spacers if needed.
  • Bond Type and Steel Quality: Air brazed or brazed edges with high-manganese steel improve heat resistance and longevity in wet or dry cutting.
  • Material Range: If you switch between glass, tile, and crystal, opt for multi-material discs to reduce tool changes.
  • Cutting Method: Wet cutting typically reduces heat, dust, and edge chipping; ensure your grinder and blade are rated for wet use if you intend to wet cut.
  • Safety Considerations: Always use eye protection, gloves, and a dust mask. Clamp workpieces securely and follow manufacturer instructions for RPM and use.

Frequently Asked Questions
