Frequently Asked Questions

  • Q: What is the difference between a Helix head and a Fast head?
    A: The Helix head features a spiral diamond pattern that draws water up to the grinding surface during use — keeping the bit cooler and extending its life while cutting fast. The Fast head uses a high-abrasion diamond coating for maximum cutting speed without the self-watering feature. The Helix is preferred for extended grinding sessions.
  • Q: What size grinder head do I need for stained glass work?
    A: The 1" standard or helix head is the most versatile choice for general stained glass grinding. Use 3/4" heads for smaller glass pieces or tighter curves. Cap heads (1/8" or 1/4") are ideal for detail work on small pieces and tight inside curves.
  • Q: What is a Radius Angle head used for?
    A: Radius Angle heads have a dual-sided hourglass and grooved profile designed for grinding lamp panel pieces, preparing edges for wire wrapping and copper foiling, and cutting precise mitered angles on glass. Essential for Tiffany-style lamp panel work.
  • Q: Should diamond grinder heads be used wet or dry?
    A: Always use wet. Glass grinder machines have a built-in water reservoir that keeps the bit and glass surface wet during grinding. Never run diamond grinder heads dry — heat buildup will rapidly degrade the diamond coating.
